AddSignstackFileReq

  • file
    Type: object
    required
    • contentType
      Type: string
      required

      MIME type of the file (e.g., application/pdf).

    • name
      Type: string
      required

      Display name for the file. Used in API responses and as part of the storage key. Doesn't need to match any original filesystem name — any human-readable label works.

    • hash
      Type: string

      SHA-256 hash of the file's bytes, hex-encoded. Optional but recommended — supplying it lets the server dedup via GET /files?hash=… and gives POST /files/{id}/verify a baseline to compare against later. SHA-256 is the only supported algorithm.
