Steps
Note that the Forms API supports 3-legged authentication only — 2-legged/service tokens cannot call it.
List a project's templates with GET https://developer.api.autodesk.com/construction/forms/v1/projects/{projectId}/form-templates.
Distinguish PDF-based forms from web forms in the template response: PDF forms expose a pdfValues array for their smart-field inputs, web forms use customValues for their defined fields.
Submit a completed form with POST forms, populating pdfValues or customValues depending on the template's form type.
List existing form submissions for a project to audit status and responses.
Confirm you're targeting current endpoint versions — some legacy Forms endpoints carry a published future deprecation date and are being superseded by newer versions.
Known gotchas
Forms is one of the few ACC APIs that outright rejects 2-legged tokens, unlike Issues or Data Management which support both flows.
Sending customValues to a PDF-type template (or vice versa) fails validation — check the template's type before building the payload.
Legacy Forms endpoint versions carry a stated deprecation timeline, so new integrations should target current versions rather than older tutorial code.
