Generate a wallet pass
Generates a wallet pass from a published template. For Apple passes (default),
returns a signed .pkpass binary file directly. For Google passes
(wallet_type: "google"), returns a JSON object containing a save_url
that the user can open to add the pass to Google Wallet.
When wallet_type: "both", generates both Apple and Google passes in a single
call. The response is always JSON with apple and google keys. Partial success
is allowed — if one wallet fails, the other is still returned with a warning.
Returns 201 if at least one succeeds.
The pass ID is returned in the X-Pass-Id response header (for single-wallet).
If the app has a validation webhook configured, the webhook is called once
before generation (not per wallet type). A webhook rejection returns 403;
a webhook error returns 502 (fail-closed).
**Scope:** passes:create

Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| x_app_id | string | no | Override X-App-Id for this call. Defaults to the MCP connection header. |
| template_id | string | yes | ID of the published template to use. |
| serial_number | string | yes | Unique serial number for this pass. |
| data | object | yes | Dynamic field values merged into the template structure. |
| external_id | string | no | Optional external identifier for cross-system lookups. |
| expires_at | string | no | Optional expiration timestamp for the pass. |
| get_or_create | boolean | no | When true, if a pass with the same serial_number already exists and is active, return the existing .pkpass (200) instead of a 409 error. The response includes an `X-Pass-Existed: true` header. If the existing pass is voided/expired, returns 409. When false (default), duplicate serials always return 409. |
| locations | array | no | GPS locations where the pass is relevant (shown on lock screen). Overrides template defaults if provided. |
| relevant_date | string | no | ISO 8601 date when the pass is relevant (appears on lock screen). |
| max_distance | number | no | Maximum distance in meters from a location for lock screen relevance. |
| wallet_type | string | no | Target wallet platform. Defaults to `apple`. When set to `google`, the response is a JSON object with a `save_url` instead of a binary .pkpass file. When set to `both`, generates both Apple and Google passes in one call and returns a JSON object with `apple`, `google`, and `warnings` keys. |
| strip_image_id | string | no | Override the template's strip/hero image for this pass only. The referenced image must belong to the same app and have purpose `strip` (or a `strip_*` variant). Applied to Apple `strip.png` and Google `heroImage` atomically (same value for both wallets in `wallet_type: "both"`). Omit or send `null` to use the template's strip image. |
