This API is subject to change. Bug fixes and new features will be released based on developer feedback throughout the preview period.
Note: The Form Submission API only works with the Wix Forms app. Call GetAppInstance to confirm that the app named wix_forms is installed on the site.
Updates a submission.
Each time the submission is updated, revision increments by 1. The existing revision must be included when updating the submission. This ensures you're working with the latest submission information, and prevents unintended overwrites.
You can only call this method when authenticated as a Wix app or Wix user identity.
