API reference

Basics

API endpoint

Depending on the Pryv.io setup or distribution, the root endpoint can have the following formats:

Pryv Lab: https://{username}.pryv.me Own Domain: https://{username}.{domain} DNS-less (Open): https://{hostname}/{username}

Each user account has a dedicated root API endpoint as it is potentially served from a different location. The API endpoint format may vary, so check your platform’s service information if needed.

You can adapt the examples with “API” selector in the top navigation bar.

Call with HTTP

The API serves regular REST-like HTTP requests, with the usual verbs for reading and manipulating data:

  • GET (parameters: query string)
    for reading resources
  • POST (parameters: request body)
    for creating new resources and other methods modifying data
  • PUT (parameters: request body)
    for modifying resources
  • DELETE (parameters: query string)
    for removing resources; logical deletion (trashing) is supported for some resources such as events and streams

Alternative HTTP request method

For those having trouble with HTTP access control (CORS) rules, the API allows web apps to fake POST, PUT and DELETE requests through application/x-www-form-urlencoded POST requests with the following fields (all optional):

_method

The HTTP override method to use (usually PUT or DELETE; POST is used if not set).

_auth

The Authorization header value (alternative to sending the header itself).

_json

Considered as the JSON request body if set (overriding all other body content, if any).

Call with websockets

The API supports real-time interaction by accepting websocket connections via Socket.io 2.0

For API versions prior to 1.5.8, use Socket.io 0.9.

Connecting

First, load the right Socket.IO client library.

Then initialize the connection with the URL:

Pryv Lab:

https://{username}.pryv.me/{username}?auth={accessToken}

Own Domain:

https://{username}.{domain}/{username}?auth={accessToken}

DNS-less:

https://host.your-domain.io/{username}/{username}?auth={accessToken}

Yes, the username is quoted 2 times…

For API versions prior to 1.5.8, append &resource={username}.

Call methods

You call API methods by sending a corresponding Socket.IO {method-id} message, passing a parameters object and a callback:

// javascript
socket.emit('{method-id}', {/*parameters*/}, function (error, result) {
  // handle result
});

See methods ids

Specific errors

invalid-method
HTTP404

The given method id is invalid.

Subscribe to changes

Get notified when data changes by subscribing to messages. Available messages are:

  • eventsChanged
  • streamsChanged
  • accessesChanged
  • systemBoot (webhooks only)

Messages do not include the content of the changes, but they describe what type of resource has been changed (created, updated or deleted). They inform the server that it needs to fetch new or updated data through the API by doing a HTTP GET request with a valid access token. The systemBoot message is executed when the notifications system is started in order to query possibly missed data changes.

With websockets

Get notified of data changes in a web application using websockets.

With webhooks

Get notified of data changes in a web service using webhooks.

Method ids

Pryv.io API methods have ids that are available at each method’s doc. For example, the id of the Get events method is events.get. This id is useful in the following:

Service info

Service information provides a unified way for third party services to access the necessary information related to a Pryv.io platform as this route is served by any Pryv.io API endpoint.

For many applications, the first step is to authenticate a user. For this you need to know the path to access which is usually set to https://access.{domain}/ or https://{hostname}/access/. Fetching the path /service/info on any valid URL endpoint will return you a list of useful informations, such as access, containing the URL to access.

See Auto-Configuration in the guide App Guidelines.

Parameters

Result

HTTP200 OK
register
string

The URL of the register service.

access
string

The URL to perform authentication requests.

api
string

The API endpoint format.

name
string

The platform name.

home
string

The URL of the platform’s home page.

support
string

The email or URL of the support page.

terms
string

The terms and conditions, in plain text or the URL displaying them.

eventTypes
string

The URL of the list of validated event types.

version
string

The API version.

Data format

The API exchanges data with clients in JSON (MIME type application/json), except when uploading/downloading attached files.

As input, the API accepts JSON payloads of maximum 10MB.

Authorization

All requests for retrieving and manipulating activity data must carry a valid access token. The preferred method is to use the HTTP Authorization header.

Access tokens are obtained via the app authentication or from sharing.

Alternative methods:

  1. Pryv.io supports the Basic HTTP Authorization Scheme This allows to present a Pryv.io endpoint as a single URL without exposing the token in query parameters:

    curl https://{token}@{username}.pryv.me/access-info

    This method is not supported by modern browsers but by tools such as cURL, the Node.js library superagent or Postman. These tools implicitly translate the ${token}@ part of the URL to the Authorization header in basic auth format. Please use the main authorization method for tools that do not operate this translation, such as Grafana.

    Note that Pryv.io does not require a username, so only the token should be Base64 encoded. For more information see RFC671.

  2. The access token can be provided in the query string’s auth parameter, for example during the Socket.IO handshake or for a direct HTTP GET call in a browser:

    curl https://{username}.pryv.me/access-info?auth={token}

Trusted apps verification

Trusted apps only 

These API methods require that the appId parameter and Origin (or Referer) header are trusted.

Only Apps that need to use a Personal token are be registered as “Trusted Apps”.

These are usually:

  1. The web app for the Authentication and Consent process such as app-web-auth3
  2. An admin panel for the end-user to manage Access Tokens and Profile.

Trusted app api methods are tagged with T

This setting can be adapted in the Pryv.io service configuration. By default, any valid appId works and the Origin (or Referer) header must be in the form https://*.{domain}, ex.: https://login.{domain}.

Authenticate your app

To authenticate users in your app, and thus for users to grant your app access to their data, you must:

  1. Choose an app identifier (min. length 6 chars)

  2. Fetch the service information

  3. Send an auth request to the URL exposed by the access parameter of the service information

  4. Open the authUrl field of the HTTP response in a browser or webframe. The web page will prompt the user to sign in using her Pryv.io credentials (or to create an account if she doesn’t have one).

  5. The result of the sign-in process: an authenticated Pryv API endpoint or a refusal can be obtained in two ways:

    • by polling the URL obtained in the poll field of the HTTP response to the auth request (preferred method)
    • by being redirected to the returnURL provided in the auth request with the result in query parameters

Generate token app

The Access token generator is a simple web application that allows its user to enter the parameters of the Auth request and performs it. It is accessible at the following URL:

https://pryv.github.io/app-web-access/?pryvServiceInfoUrl=${pryvServiceInfoUrl}

For example:

https://pryv.github.io/app-web-access/?pryvServiceInfoUrl=https://reg.pryv.me/service/info

Common metadata

General API and server information.

In HTTP headers

Every HTTP response has header:

API-Version

The version of the API in the form {major}.{minor}.{revision}. Mirrored in method results as meta.apiVersion.

Pryv-Access-Id
optional

The id of the Access used for the API call. Only present if a valid access token has been provided.

In method results

Every JSON method result has properties:

meta.apiVersion

The version of the API in the form {major}.{minor}.{revision}. Mirrored in HTTP header API-Version.

meta.serverTime

The current server time as a timestamp. Keeping track of server time is necessary to properly handle time in API calls.

meta.serial

The serial will change every time the core or register is updated. If you compare it with the serial of a previous response and notice a difference, you should reload the service information.

Errors

When an error occurs, the API returns a response with an error object (see error detailing the cause. (Over HTTP, the response status is set to 4xx or 5xx.) In this documentation, errors are identified by their id.

Usual errors

See also error data structure.

invalid-request-structure
HTTP400

The request’s structure is not that expected; for example: invalid JSON syntax, unexpected multipart structure when uploading file attachments.

invalid-parameters-format
HTTP400

The request’s parameters do not follow the expected format. The error’s data contains an array of validation errors.

unknown-referenced-resource
HTTP400

One or more referenced resource(s) can’t be found. The error’s data.{method-parameter-key} (e.g. data.streamId) contains the unknown reference(s).

invalid-access-token
HTTP401

The access token is missing or invalid.

forbidden
HTTP403

The given access token does not grant permission for this operation. See accesses for more details about accesses and permissions.

unknown-resource
HTTP404

The resource can’t be found.

removed-method
HTTP410

The resource or method has been removed from the API.

too-many-results
HTTP413

The events.get method in batch or websocket call yielded too many results. Call the API method directly, narrow the request scope or page the request.

user-account-relocated
HTTP301

The user has relocated her account to another server. Both the Location header and the error’s data contain the equivalent URL pointing to the physical server now hosting the user’s account. This error can only occur between the moment the account is relocated and the moment your DNS is updated to point to the new server. So we’re stretching the HTTP convention a little, in that the returned URL should not be used permanently (only until {username}.pryv.me points to the correct server again). It’s up to you to decide whether to keep it for the duration of the session (if you use sessions), for a given time, etc.

user-intervention-required
HTTP402

The request cannot be served temporarily because the user’s account has exceeded its limits. The user must log into her account and fix the issue.

Create HF event

Yidhfs.createHTTPPOST /events

Creates a new event that will be holding HF series.

Parameters

The new event’s data: see Event.

The content of HF events is read-only, so you should not provide any content. However, the event type should correspond to the type of the data points in the series, prefixed with series:. For example, to store HF series of mass/kg data points, the type of the holder event should be series:mass/kg.

Result

HTTP201 Created
event
event

The created event.

Specific errors

invalid-operation
HTTP400

The referenced stream is in the trash, and we prevent the recording of new events into trashed streams.

invalid-parameters-format
HTTP400

The event content’s format is invalid. Events of type High-frequency have a read-only content.

Get HF series data points

Yidhfs.getHTTP-onlyGET /events/{id}/series

Retrieves HF series data points from a HF event. Returns data in order of ascending deltaTime between “fromTime” and “toTime”. Data is returned as input, no sampling or aggregation is performed.

Parameters

fromDeltaTime
timestampoptional

Only returns data points later than this deltaTime. If no value is given the query will return data starting at the earliest deltaTime in the series.

toDeltaTime
timestampoptional

Only returns data points earlier than this deltaTime. If no value is given the server will return only data that is in the past.

Result

HTTP200 OK

The HF series data points.

Add HF series data points

Yidhfs.addHTTP-onlyPOST /events/{id}/series

Adds new HF series data points to a HF event.

The HF series data will only store one set of values for any given deltaTime. This means you can update existing data points by ‘adding’ new data with the original deltaTime.

Parameters

The new HF series data point(s), see HF series.

Result

HTTP200 OK
status
string

The string “ok”.

Specific errors

invalid-operation
HTTP400

The event is not a HF event.

invalid-operation
HTTP400

The referenced HF event is in the trash, and we prevent the recording of new data points into trashed events.

Add HF series batch

Yidhfs.addBatchHTTP-onlyPOST /series/batch

Adds data to multiple HF series (stored in multiple HF events) in a single atomic operation. This is the fastest way to append data to Pryv; it allows transferring many data points in a single request.

For this operation to be successful, all of the following conditions must be fulfilled:

  • The access token needs write permissions to all series identified by “eventId”.
  • All events referred to must be HF events (type starts with the string “series:”).
  • Fields identified in each individual message must match those specified by the type of the HF event; there must be no duplicates.
  • All the values in every data point must conform to the type specification.

If any part of the batch message is invalid, the entire batch is aborted and the returned result body identifies the error.

Parameters

format
string

The format string “seriesBatch”.

data
array

Array of batch entries. Each batch entry is defined as follows:

eventId
string

The id of the HF event.

data
object

HF series data to add to the HF event.

Result

HTTP201 Created
status
string

The string “ok”.

Specific errors

invalid-request-structure
HTTP400

The request was malformed and could not be executed. The entire operation was aborted.

Update HF event

Yidhfs.updateHTTPPUT /events/{id}

Similar to the standard Update event method.

You may update all non read-only fields, except content which is read-only for HF events.

Specific errors

invalid-parameters-format
HTTP400

The event content’s format is invalid. Events of type High-frequency have a read-only content.

Delete HF event

  • If the stream is already in the trash, it will be irreversibly deleted with its descendants (if any). If events exist that refer to the deleted item(s), you must indicate how to handle them with the parameter mergeEventsWithParent.

Parameters

id
identifierHTTPset in request path

The id of the stream.

mergeEventsWithParent
boolean

Required if actually deleting the item and if it (or any of its descendants) has linked events, ignored otherwise. If true, the linked events will be assigned to the parent of the deleted item; if false, the linked events will be deleted.

Result: trashed

HTTP200 OK
stream
stream

The trashed stream.

Result: deleted

HTTP200 OK
streamDeletion
item deletion

Accesses

Methods to retrieve and manipulate accesses, e.g. for sharing. Any app token can manage shared accesses it created. Full access management is available to personal tokens.

Get accesses

idaccesses.getHTTPGET /accesses

Gets accesses that were created by your access token, unless you’re using a personal token then it returns all accesses. Only returns accesses that are active when making the request. To include accesses that have expired or were deleted, use the includeExpired or includeDeletions parameters respectively.

Parameters

includeExpired
booleanoptional

If true, also includes expired accesses. Defaults to false.

includeDeletions
booleanoptional

If true, also includes deleted accesses. Defaults to false.

Result

HTTP200 OK
accesses
array of accesses

All manageable accesses in the user’s account, ordered by name.

accessDeletions
array of deleted accesses

If requested by includeDeletions, the access deletions, ordered by deletion time.

Create access

idaccesses.createHTTPPOST /accesses

Parameters

An object with the new access’s data: see access.

Result

HTTP201 Created
access
access

The created access.

Specific errors

invalid-item-id
HTTP400

The specified token is invalid (e.g. it’s a reserved word such as null).

Delete access

idaccesses.deleteHTTPDELETE /accesses/{id}

Deletes the specified access. Personal accesses can delete any access. App accesses can delete shared accesses they created. Deleting an app access deletes the shared ones it created. All accesses can also perform a self-delete unless a forbidden selfRevoke permission has been set.

Parameters

id
identifierHTTPset in request path

The id of the access.

Result

HTTP200 OK

The type of log.

time
timestampread-only

The time the API call was executed.

HF series

High-frequency series are collections of homogenous data points.

To store a HF series in Pryv.io, you must first create a HF event.

Series data is encoded in the “flatJSON” format:

  • Each data point in a series has a "deltaTime" field that indicates its time difference, since the holder event’s timestamp. If a "timestamp" field is instead provided, the corresponding "deltaTime" will be automatically computed from the holder event’s timestamp.
  • For types that store a single value (e.g. “mass/kg”), a single additional field named "value" is created.
  • Types that contain multiple properties (e.g. “position/wgs84”) will have many fields, whose names can be inferred from the type reference.
  • Optional fields can either be provided or not; omitted values will be set as null.
format
string

The data format (for now only “flatJSON” format is supported).

fields
Array of fields

The “fields” array lists all the fields that you will be providing in the “points” array, including the “deltaTime” field in first position. If the data type contains a single field (ex.: mass/kg), the second field is “value”, otherwise, it is the list of fields with the required ones first.

points
Array of data points

The “points” array contains the data points, each data point is represented by a simple array. This makes the bulk of the message (your data points) very space-efficient; values are encoded positionally. The first value corresponds to the first field, and so on.

Webhook

Webhooks provide push notifications to web servers using HTTP POST requests.

Once created, they will run, executing a HTTP POST request to the provided URL for each data change in the user account.

When the webhooks service is booted, it will send a webhooksServiceBoot message to all active webhooks. This allows to query the API for potentially missed notifications during its down time.

Only the app access used to create the webhook or a personal access can retrieve and modify it. This is meant to separate the responsibilities between the actor that sets the webhooks and the one(s) that consume the data following the webhook setup.

id
identifierread-only

The identifier of the Webhook.

accessId
identifierread-only

The identifier of the access that was used to create the Webhook.

url
stringunique per app accessread-only (except at creation)

The URL where the HTTP POST requests will be made. To identify the source of the webhook on your notifications server, you can use the url’s hostname, path or query parameters. For example:

{
  "url": "https://${username}.my-notifications.com/${my-secret}/?param1=value1&param2=value2"
}
minIntervalMs
numberread-only

The webhooks run rate is throttled by a minimum interval between HTTP calls in milliseconds, sending an array of changes that occured during this period. Its value is set by the platform admin.

maxRetries
numberread-only

In case of failure to send a request, the webhook will retry maxRetries times at a growing interval of time before becoming inactive after too many successive failures. Its value is set by the platform admin.

currentRetries
numberread-only

The number of retries iterations since the last failed HTTP call. This number is 0 if the last HTTP call was successful.

state
active|inactive

The current state of the Webhook. An inactive Webhook will not make any HTTP call when changes occur. It must be activated using the update webhook method.

runCount
numberread-only

The number of times the Webhook has been run, including failures.

failCount
numberread-only

The number of times the Webhook has failed HTTP calls. Failed runs are HTTP requests that received a response with a status outside of the 200-299 range or no response at all.

lastRun
Run objectread-only

Represents the last Webhook call, comprised of its HTTP response status and timestamp.

status
number

The HTTP response status of the call.

timestamp
timestamp

The time the call was started.

runs
array of Run objectsread-only

Array of Run objects in inverse chronological order (newest first) which allows to monitor a webhook’s health. Its length is set by the platform admin.

created
timestampread-only

The time the webhook was created.

createdBy
identifierread-only

The id of the access used to create the webhook.

modified
timestampread-only

The time the webhook was last modified.

modifiedBy
identifierread-only

The id of the last access used to modify the webhook.

Item deletion

A record of a deleted item for sync purposes.

id
identifier

The identifier of the deleted item.

deleted
timestampoptional

The time the item was deleted.

Key-value

An object (key-value map) for client apps to store additional data about the containing item (stream, event, etc.), such as a color, a reference to an associated icon, or other app-specific metadata.

Adding, updating and removing client data

When the containing item is updated, additional data fields can be added, updated and removed as follows:

  • To add or update a field, just set its value; for example: {"clientData": {"keyToAddOrUpdate": "value"}}
  • To delete a field, set its value to null; for example: {"clientData": {"keyToDelete": null}}

Fields you don’t specify in the update are left untouched.

Naming convention

The convention is that each app names the keys it uses with an {app-id}: prefix. For example, an app with id “riki” would store its data in fields such as "riki:key": "some value".

Error

id
string

Identifier for the error.

message
string

A human-readable description of the error.

data
any typeoptional

Additional machine-readable details (specified for each error if relevant).

subErrors
array of errorsoptional

Lists the detailed causes of the main error, if any.

streams query

The streams parameter for events.get query accepts an array of streamIds or a streams query for more complex requests.

Syntax:

The streams query must have at least one any property, with an optional not:

{ "any": ["streamA", "streamB"], "all": ["streamC"], "not": ["streamD"] }
  • any: any streamId must match
  • all: all streamIds must match
  • not: none of the streamIds must match

The returned events will be those matching all of the provided criteria.

Example:

To select all the events that are in activity or nutrition, tagged in health, but not in private:

{
  "any": ["activity", "nutrition"],
  "all": ["health"],
  "not": ["private"]
}

Format:

The JSON object representing the query must be sent stringified when passed as query parameter in a GET /events HTTP call. It can be sent as-is for batch and socket.io calls.

Item identifier

A string uniquely identifying an item for a given user. For some types of items (e.g. “structural” ones such as streams), the identifier can be optionally set by API clients; otherwise it is generated by the server. Event ids are always collision-resistant cuids.

Timestamp

A positive floating-point number representing a number of seconds since any reference date and time, independently from the time zone. Because date and time synchronization between server time and client time is done by the client simply comparing the current server timestamp with its own, the reference date and time does not actually matter (but we do use standard Unix epoch time).

Integrity

An integrity hash computed from the JSON object it is contained in. The hash is prefixed with the data structure it is computed for, as well as a representation version.
