Errors / campaign_not_stoppable

Campaign can no longer be changed

HTTP 409invalid_requestcampaign_not_stoppable

The campaign has finished, so there is nothing left to stop.

What to do

A campaign that is still sending can be stopped and the remainder will not go out. One that has completed cannot — those messages are already with the carriers.

What it looks like

{
  "error": {
    "type": "invalid_request",
    "code": "campaign_not_stoppable",

Quote the request_id if you get in touch. It is on every response, including this one, and it turns a support email into a single log query rather than an archaeology exercise.
