The contact unsubscribed webhook is triggered whenever a contact in theMarketer unsubscribes from the Email channel. This includes unsubscribing directly from the email, using the unsubscribe link, or unsubscribing through one-click unsubscribe.

Here you can find a sample payload, using default system attributes. For contacts, you can also add custom attributes to the payload, directly from the setup interface.

{
  "email" : "{{client_email}}",
  "firstname" : "{{client_firstname}}",
  "lastname" : "{{client_lastname}}",
  "phone" : "{{client_phone}}"
}
