# Start matchmaking application autofill

`projects.start_matchmaking_application_autofill`

Start asynchronous autofill for a Project's matchmaking application using its current notes, existing prepared files, and selected evidence sources. Read the autofill preparation first, then pass its revision and a UUID idempotency key. Poll the returned run id with projects.get_matchmaking_application_autofill. Changing preparation and starting again creates a new run and may supersede an active run for the same application and principal.
