Leanplum Postbacks & Batch API

  title: Leanplum A/B Tests Postbacks & Batch API
  version: 1.0.6
  description: 'The Leanplum (Leanplum by CleverTap) REST API. All requests are made to https://api.leanplum.com/api and are dispatched by an `action` parameter that names the method to run (for example action=track or action=sendMessage). Every request carries `appId`, a permission-scoped `clientKey`, and `apiVersion`; most requests also carry a `userId` and/or `deviceId`. Requests may be sent as GET (arguments as query parameters) or POST (arguments in a JSON or multipart body). Multiple actions can be batched with the `multi` method.


    Operating status note: Leanplum was acquired by CleverTap in 2022 and now operates as "Leanplum by CleverTap." The documented API surface below remains active during customer migration to CleverTap; CleverTap has wrapped its own methods behind these Leanplum API methods to ease that transition. Endpoint method names are grounded in the public Leanplum API reference; request/response schemas are modeled and should be verified against the live docs.'
