  title: Adobe Creative Cloud Firefly Generative Fill
  summary: Upload a source image and a mask, then fill the masked region with AI-generated content.
  description: >-
    Generative fill (inpainting) with Adobe Firefly. The workflow uploads the
    source image and the mask image to Firefly temporary storage, capturing an
    upload ID for each, then calls the fill endpoint with both references and a
    prompt describing what to generate inside the masked region while the rest
    of the image is preserved. Every step spells out its request inline,
    including the bearer token and x-api-key, so the flow can be read and run
    without opening the underlying OpenAPI description.
