# messenger_gift_image_upload

Upload one gift image in the Messenger app (pApp D00003). Requires target {kind:"create"} or {kind:"product", productId} and upload from this computer (PNG, JPEG or GIF under 5,000,000 bytes, as the console allows): upload {kind:"local-file", filename, byteLength, sha256} returns one presigned PUT with its headers and the console gift editor link; send the file, then call again with upload {kind:"complete", uploadId, parts:[{partNumber:1, etag}]}. The server never receives the file or downloads a link. Write: uploads to storage only; use the taskId as imageUploadTaskId. A lost receipt stays pending and is never resent; task_resume only observes, and prepared work needs the identical apply. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.

| `upload.byteLength` | Yes | When `upload.kind` is `local-file`: integer; greater than 0; The exact file size in bytes (for example from `wc -c < FILE` or `stat`). |
| `upload.sha256` | No | When `upload.kind` is `local-file`: string; pattern `^[0-9a-f]{64}$`; The SHA-256 of the file in lowercase hex (shasum -a 256 FILE). Required when the upload answers UPLOAD_CHECKSUM_REQUIRED. |
| `upload.uploadId` | Yes | When `upload.kind` is `more-parts`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `upload.fromPart` | Yes | When `upload.kind` is `more-parts`: integer; minimum 1; maximum 10000 |
| `upload.uploadId` | Yes | When `upload.kind` is `complete`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `upload.parts` | Yes | When `upload.kind` is `complete`: array; min items 1; max items 10000 |
| `upload.parts[].partNumber` | Yes | When `upload.kind` is `complete`: integer; minimum 1; maximum 10000 |
| `upload.parts[].etag` | Yes | When `upload.kind` is `complete`: string; min length 1; max length 200 |
| `upload.measured` | No | When `upload.kind` is `complete`: object; What the video measures on this computer, read with measureCommand. |
| `upload.measured.durationSeconds` | Yes | When `upload.kind` is `complete`: number; maximum 1000000; greater than 0; Video duration in seconds (ffprobe format.duration). |
| `upload.measured.frameRate` | Yes | When `upload.kind` is `complete`: number; maximum 1000; greater than 0; Frames per second (ffprobe avg_frame_rate, for example 30000/1001 = 29.97). |
| `upload.measured.width` | Yes | When `upload.kind` is `complete`: integer; maximum 100000; greater than 0 |
| `upload.measured.height` | Yes | When `upload.kind` is `complete`: integer; maximum 100000; greater than 0 |
| `upload.measured.frameRateMode` | No | When `upload.kind` is `complete`: `CFR`, `VFR`; Constant or variable frame rate, when the tool reports it. |
| `upload.measured.minFrameRate` | No | When `upload.kind` is `complete`: number; maximum 1000; greater than 0 |
| `upload.measured.maxFrameRate` | No | When `upload.kind` is `complete`: number; maximum 1000; greater than 0 |
| `upload.uploadId` | Yes | When `upload.kind` is `cancel`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `confirmToken` | No | string; pattern `^ct[a-f\d]{32}$`; The confirmToken from this tool's preview result. Omit it to preview; repeat the same input with it to execute. |
