Submit a set of portrait photos and asynchronously generate 60 professional AI headshots.
This is an asynchronous endpoint. The API returns immediately with
a headshots_id; Runflow then POSTs the finished results to your
callback_url when processing is complete (estimated 1–2 hours).
The image_urls in the callback payload expire after 24 hours —
save them to your own storage immediately upon receipt. See the
Webhooks guide for a full handler example.
Your Runflow API key. Include it in the x-api-key header on every
request. Keys are issued per customer — contact the founders
to get one.
