Forms

Save answers to a submission

PATCH/submissions/{id}
forms:writeupdate_submissionIdempotent

Saves the answers you send (field id to value) and keeps the rest, with no validators, so a draft can be filled in steps. A completed submission can still be edited, except a masked field, which is 409 conflict keyed answers.<field id>. An id that is not a field of the form is 422 exists. Emits submission.updated with changed_fields when answers change; sends no email. Sending the old answers undoes it.

Path parameters

  • idstring (uuid)Required#

    The submission's id, a uuid. An unknown id, or a submission you cannot see, returns 404.

Query parameters

  • dry_runboolean#

    Validate and run the call without committing it, returning what the real call would return with meta.dry_run set.

Request body

application/json, required · FormSubmissionUpdate

  • answersobjectRequired#

    Answers keyed by form field id. Only the keys you send change. A masked field cannot change once the submission is completed.
