Upload an image
Uploads an image for use in pass templates or per-pass strip overrides.
Send as multipart form data with a purpose field and a file field
containing the PNG image.
**Upload behaviour by purpose:**
strip— **accumulates**. Each upload creates a new image; the returned
id can be passed as strip_image_id on POST /v1/passes or
PATCH /v1/passes/{id} to give individual passes their own banner.
Previous strip images are NOT deleted — manage them via
DELETE /v1/images/{id} when no longer referenced.
- All other purposes (
icon,logo,thumbnail,background,footer,
and all _2x/_3x variants) — **replace-on-upload**. Uploading a new
image of the same purpose deletes the previous one from storage and DB.
These are app-wide template assets, not per-pass.
**Scope:** images:manage
Maps to OpenAPI operationId uploadImage — POST /manage-images.
Same PassFast HTTP API, billing, and rate limits. Do not invent other paths.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| x_app_id | string | no | Override X-App-Id for this call. Defaults to the MCP connection header. |
| purpose | string | yes | The intended use of the image. `strip` uploads accumulate (for per-pass `strip_image_id` overrides); all other purposes replace existing uploads of the same purpose for the app. |
| file_base64 | string | yes | Base64-encoded file bytes. Maps to the OpenAPI multipart `file` field — same uploadImage (or equivalent) endpoint, not a new API. |
| filename | string | no | Optional filename sent with the multipart upload. |
