We created a new viewing experience for our SMS API documentation. It's now all in one central location. Click here to check it out!

Opt a user out of one list or all lists. Typically a user will opt out of your lists themselves however if you offer alternative methods such as handling opt out requests via telephone support, this call might be useful for you. Possible results from this method are:

OPTED_OUT - recipient was opted out succesfully.
OPTOUT FAILED - recipient was not opted out because they did not exist on the contact list.

  • list_id - integer - the list id as a numeric value, this can be found by requesting 'contact-lists.get' and using corresponding id values from the dataset
  • mobile - string - recipients mobile number in INTERNATIONAL format (the mobile number as returned in a 'contact-lists.get-recipients' call)
