How it runs

The automated pipeline, trigger to output.

  • TriggerWebhook receives creative brief payloadHTTP webhook
  • ActionRender base hero concept with generate-imageImage generation

  • ActionRender each placement-sized variantImage generation
  • ActionUpload every sized file to R2CloudflareCloudflare R2
  • OutputReturn placement-to-URL map to webhook callerHTTP webhook

What it does

Takes a single inbound creative brief and produces a complete, placement-ready image set: one base concept rendered into every aspect ratio your ad channels require (square, story, landscape, banner). Each size lands in object storage and the workflow returns the full URL map so a downstream ad-ops system can ingest it immediately.

When to use it

Use it when a creative or campaign tool needs to call out and get back every ad size for a concept in one shot. It removes the manual resize-and-crop chore and guarantees no placement ships missing its asset, which is the usual cause of paused ad sets.

How it works

  1. 1An HTTP webhook receives a brief payload (concept, copy, channel list).
  2. 2generate-image renders the base hero concept at full resolution.
  3. 3The workflow loops over each required placement size.
  4. 4For each size it produces a correctly framed render via generate-image.
  5. 5Every sized file is uploaded to R2 under a brief/placement key.
  6. 6The workflow responds to the webhook with a JSON map of placement to R2 URL for ad-ops ingestion.
