Summary

Generate signed upload URLs for media or document files through the PostFast API. Choose the file MIME type and number of URLs; use a returned storage key when creating a post with uploaded media or a document attachment.

Inputs

  • Content Type (required) — MIME type of the file: PDF, PowerPoint, Word, GIF, JPEG, PNG, WebP, MOV, MP4, QuickTime, or WebM. Defaults to image/jpeg.
  • Count — Number of upload URLs to generate, from 1 to 8; defaults to 1. Video and document types allow only 1 per request.

Output shape

One or more JSON items containing the API response, or one JSON item if the response is an object.

The operation sends the selected content type and count to PostFast’s signed-upload-URLs endpoint. The response is passed through; the node does not upload file data itself. Use the returned S3 key in a later post operation.
