How do you connect a generation form to a real backend?

A generation form should submit the user’s intent once and then follow the server’s job state. It should not infer completion from the request merely being accepted.

Use the agreed contract

Validate required fields for immediate feedback and repeat validation on the server. Send only the fields the endpoint expects. On acceptance, store or navigate to the returned job identifier. Keep secret credentials and provider calls behind trusted server boundaries.

Handle uncertain responses

Preserve the brief when a request fails. Distinguish validation errors from a lost connection, where the server may already have created a job. Use the application’s duplicate-request policy when retrying. Test a successful submission, invalid input, repeated clicks, and a response interrupted after acceptance. The visible result should always reflect what the application knows, not an optimistic assumption that a video exists.
