Capture Leads (Async)

Captures leads from all sources. Functionality is the same as the synchronous Capture Leads API, with the following differences –

  1. API host is different, see Async API.
  2. An additional x-api-key must be passed in the header, see Async API. Content-Type is application-json.
  3. Returns a RequestId parameter. This must be passed in the Status API to get the status of the request.
  4. To get metrics for this Async API, see Get Capture Leads Metrics API.

Note: The request body is identical to the synchronous Capture Leads API.
