Bulk add users to the suppression list. Use this endpoint to suppress multiple destinations (e.g. email addresses or phone numbers) on a given channel in a single request, instead of calling Add User to Suppression List once per user.

Each item in the batch array is one user to suppress. The batch is processed asynchronously, and a 202 response means it has been accepted for processing.

Example request:

POST {{API_URL}}/v1/{{WSID}}/suppressions/ingest

{
  "batch": [
    {
      "destination": "abcde@fghi.com",
      "channel": "email"
    }
  ]
}

{
  "status": "success"
}
