Update optout list

Update or Merge to an existing optout list.


Name Parameter
Data Type Description
Authorization: Header False Required String (Bearer {access token}) Pass the authentication token that was granted when you authorized access.
file Body False Required File The input file in CSV format.


Request Notes

The input file for your merge should include only a list of email addresses, 1 per line. Time stamp and origin are added by Act-On automatically.

If there are duplicate email addresses (either in the uploaded list or already existing as optout records) no error occurs.


When a file is uploaded as a parameter for updating a list, a job id is returned. To obtain an upload status, query the job id.

A successful request results in an HTTP 200 response in JSON like the following:

Status can be queried as follows:

GET /api/1/list/{jobid}/status

This returns a JSON object similar to the following. A successful list upload results in a return of the list id along with a listing of the quantities of appended, updated, failed and rejected records.

If there are rejected records then the status return will include a value for “rejectedRecordsURL”. The API call GET api/1/list/rejectedUploadRecords can then be used to retrieve the file containing the rejected records.
