# GET /v1/catalogue/flashings/{templateId}

**Service:** Catalogue  
**Operation:** `CatalogueService_GetFlashing`

Returns the full flashing template, including its thickness and selectable colours.

## Parameters

| Parameter | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `templateId` | path | string | yes | The id of the flashing template to retrieve. Required. |
| `fields` | query | string | no | Comma-separated response fields to include, using camelCase JSON names (e.g. `orderId,total.amountMicros`). Dot paths reach into nested objects and map transparently across arrays. Paths are relative to the resource, not the response envelope; envelope keys like `nextPageToken` are always preserved. Only 2xx JSON responses are filtered; error bodies pass through unmodified. Unknown names are silently ignored. Takes precedence over `excludeFields` when both are provided. |
| `excludeFields` | query | string | no | Comma-separated response fields to exclude, using camelCase JSON names. Dot paths and array-transparency work the same as `fields`. Paths are relative to the resource, not the response envelope. Only 2xx JSON responses are filtered; error bodies pass through unmodified. Ignored when `fields` is also provided. |

## Responses

| Status | Schema | Description |
| --- | --- | --- |
| 200 | `GetFlashingResponse` | A successful response. |
| 400 | `Error` | The request was rejected because it was malformed — for example a badly formed id. The body is a validation-failure envelope: an overall type and message and one entry per problem (each with a stable code, a message, and a param pointing at the offending parameter). |
| 401 | `Error` | The request is missing a valid bearer token, or the token is invalid or expired. |
| 403 | `Error` | The token is valid but does not permit this action, or the resource belongs to a company the token cannot act for. The error type is permission_denied. |
| 404 | `Error` | No flashing template with the given id exists for the authenticated company. |
| 429 | `Error` | The request was throttled (rate_limited) or exceeded a size limit (resource_exhausted). When throttled, the Retry-After header says how many seconds to wait before retrying; a resource_exhausted request will fail the same way if retried unchanged. |
| default | `Error` | Any other error. The body is the same error envelope every error uses: a short stable type identifying the kind of failure (for example "rate_limited" or "internal"), a human-readable message, and the request's idempotency key echoed back when one was supplied. |

## Returns

`GetFlashingResponse`

| Field | Type | Description |
| --- | --- | --- |
| `flashing` | Flashing | The requested flashing template. |
| `flashing.templateId` | string | The template's unique id. Reference this on a flashing line item. |
| `flashing.productType` | string | The catalogue product type of this template. Flashing templates report "Flashing"; it marks them apart from other kinds of catalogue product. |
| `flashing.thickness` | string | The thickness this template is for, as a decimal string in the template's units (e.g. "0.55", millimetres for metric accounts). Fixed for the template: each thickness is a separate template with its own id, so to order a different thickness, select the template (`templateId`) that has it. |
| `flashing.flashingId` | string | The id of the underlying flashing. |
| `flashing.flashingName` | string | The display name of the underlying flashing. |
| `flashing.materialId` | string | The id of the template's material selection. Not populated yet: empty for every template today, and may start being returned in a later release without a version change. Use `flashingId` to identify the flashing. |
| `flashing.materialName` | string | The display name of the template's material selection. Empty today, like `materialId`. |
| `flashing.colours` | string[] | The colours you can select for a flashing line built on this template. A line's colour must be one of these. Colour is the per-line choice; the thickness is fixed by the template id (see `thickness`). |
