A/B Tests

Create A/B Tests using the /api/experiments endpoint. An experiment or A/B test is a set of distinct push notification variants sent to subsets of an audience. You can create up to 26 notification variants and send each variant to an audience subset.

Create experiment (A/B Test)

Create an experiment. The body of the request should consist of a single experiment object. The experiment is processed and sent immediately unless a schedule is present.

Validate experiment

Accepts the same range of payloads as /api/experiments, but only parses and validates the payload without creating the experiment. This does the same amount of validation as the creation endpoint, including platform-specific validation, e.g., APNs byte limit checks. While this operation ensures the experiment is technically valid, it does not guarantee that a resulting push will succeed. An experiment may validate and still fail to be delivered. For example, you may have a valid experiment with no devices in your audience.

POST /api/experiments/validate

Security:

Request body:

A single experiment object.

  • Content-Type: application/json

    An experiment object describes an A/B test, including the audience and variant portions.

Responses

  • 200

    The experiment is valid.

    • Content-Type: application/json
      OBJECT PROPERTIES
      • ok booleanREQUIRED

        If true, the operation completed successfully and returns an expected response.

      • operation_id string

        A unique string that represents a single API call, used to identify the operation or side effects in reporting and troubleshooting logs.

  • 400

    There was a parsing or validation error in the request. Bad Request errors typically include path and location in the response to help you find the cause of the error.

    • Content-Type: application/json

      Errors returned with 4xx responses. Errors include as much information as possible to help you understand the reason for the failure.

  • 401

    Authentication information (the app key and secret or bearer token) was either incorrect or missing.

    • Content-Type: text/plain

      Errors returned with 4xx responses. Errors include as much information as possible to help you understand the reason for the failure.
