# GET /v1/suppliers

**Service:** Suppliers  
**Operation:** `SupplierService_ListSuppliers`

Returns a paginated list of your company's suppliers. Useful for discovering supplier ids to pass as filters on the inventory list. Suppliers are ordered alphabetically by name.

## Parameters

| Parameter | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `pageSize` | query | integer | no | Maximum number of suppliers to return per page. 0 uses the server default; the server may cap the value. |
| `pageToken` | query | string | no | Opaque page token from a previous response, used to fetch the next page. |
| `name` | query | string | no | Optional: only return suppliers whose name contains this text (case-insensitive substring match). |
| `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 | `ListSuppliersResponse` | A successful response. |
| 400 | `Error` | The request was rejected because it was malformed — for example an unusable page token or an invalid filter value. 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. |
| 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

`ListSuppliersResponse`

| Field | Type | Description |
| --- | --- | --- |
| `suppliers` | Supplier[] | The suppliers in this page. |
| `suppliers.supplierId` | string | The supplier's unique id. |
| `suppliers.name` | string | The supplier's name. |
| `nextPageToken` | string | Token to pass as `pageToken` to fetch the next page; empty when there are no more results. |
