Successful Submission

  "SplitNumber": 1,
  "RecipientList": "subscribers.csv"

Failed Submission

Potential errors:

File not found for audience list id '{listId}'
No deployment found for  '{listId}'
Deployment '{trackId}' associated with this file was created within the Omail portal and is not eligible for API access.
Deployment '{trackId}' assocated with this file has been edited from the Omail portal and is not eligible for API access. Last edited by {userName} on {changedDate}.
List removed: Audience list '{fileName}' was removed by {userId} on {removalDate}.

A failed POST submission may be due to several factors:

Status Description
400 Bad Request Typically, this error occurs when the request does not follow the specifications.
403 Forbidden Typically, this error occurs when the credentials are erroneous. Potentially, an incorrect x-omeda-appid.
404 Not Found Typically, this error occurs with a malformed URL or the resource that is searched for is not found. This can occur if the ListId submitted in the url is not found in Omail.
405 Method Not Allowed Typically, this error occurs when the resource accessed is not allowed by the HTTP Method utilized. Make sure you employ the correct HTTP Method (GET) for this request.
409 Conflict Typically, this error occurs when their was a problem during the list assignment process associated with the content of the list. Example: File contained no valid recipient records.

This is not an exhaustive list of errors, but common ones. If an error occurs repeatedly, please contact your Omeda representative.
