Prerequisites to accessing the API

To authenticate to the Platform API, use the API Credentials interface to create a Client ID and Secret, then use these credentials to fetch an OAuth access token.


Once your API user is set up, you can authenticate by issuing a POST request to mParticle’s SSO token endpoint.

The JSON body of the request must contain:

  • client_id - your Client ID, issued by mParticle
  • client_secret - your Client Secret, issued by mParticle
  • audience - set to a value of ""
  • grant_type - set to a value of "client_credentials"

Curl Syntax

curl --request POST \
  --url \
  --header 'content-type: application/json' \
  --data '{"client_id":"...","client_secret":"...","audience":"","grant_type":"client_credentials"}'

Sample Raw HTTP Request

POST /oauth/token HTTP/1.1
Content-Type: application/json

  "client_id": "your_client_id",
  "client_secret": "your_client_secret",
  "audience": "",
  "grant_type": "client_credentials"
Using your Bearer Token

A successful POST request to the token endpoint will result in a JSON response as follows:

  "access_token": "YWIxMjdi883GHBBDnjsdKAJQxNjdjYUUJABbg6hdI.8V6HhxW-",
  "expires_in" : 28800,
  "token_type": "Bearer"

Subsequent requests to the API can now be authorized by setting the Authorization header as follows:

Authorization: Bearer YWIxMjdi883GHBBDnjsdKAJQxNjdjYUUJABbg6hdI.8V6HhxW-


Once you have authenticated, the API resources can be accessed at Subsequent updates to the API that introduce breaking changes will be published with a new version number in the URL.

Specifying your Account ID

Unless otherwise stated in the documentation for the specific resource group you are using, all API calls require you to pass in your AccountId as a querystring parameter. Forgetting to add the AccountId parameter when required will result in a 401 Unauthorized response. All subsequent entities that you work with will be within the scope of the chosen account ID. Attempting to access or modify entities outside the specified Account ID scope will return 404 - Not Found.

Sending Data

Unless otherwise stated in the documentation for the specific resource group you are using, all POST/PUT requests should send JSON as the Request Payload, with Content-Type set to application/json.

Return Data

Unless otherwise stated in the documentation for the specific resource group you are using, if an API request returns data, it will be wrapped in a common JSON structure.

  "data": [],
  "dataType": "app",
  "errors": [
        "code": "VALIDATION_ERROR",
        "message": "Error message here"

One or more entities will be returned as an array in the data property. If errors were encountered, they will be available as an array of error objects.

Status Codes

The following table lists the status codes that are returned by API requests:
