Unschedule letter

POST
/api/v2/letters/{letterUuid}/actions/unschedule

Schedule an existing letter by its unique identifier, or generate and schedule a new letter by using the unique identifier of a template.

What is the letter or template’s unique identifier? The unique identifier is an alphanumeric string, often around ten digits. It looks like abcdefhijk.

How does the API behave when a given letter or template has a specific status?

  • If the letter is a draft, or it’s already been scheduled but not yet published, then Letterhead will reschedule that letter for the desired time.
  • If the letter has already been published, then Letterhead won’t resend it, and the API will return a 400 .
  • If the template is active, then Letterhead will use that template to create an all-new email, produce it, and schedule it at the desired time.
  • If the template is inactive, however, then Letterhead will assume your organization doesn’t want it used and our API will return a 400.
