# Retrieve a coupon

Source: https://developers.swell.is/backend-api/coupons/retrieve-a-coupon

Retrieve an existing coupon using the ID that was returned when created.

## Arguments

- `id` (objectId, required): The ID of the coupon to retrieve.
- `expand` (string): Expanding link fields and child collections is performed using the expand argument.

  - For example, `expand=account` would return a related customer account if one exists.

  When the field represents a collection, you can specify the query limit.

  - For example, `expand=variants:10` would return up to 10 records of the variants collection.

  See [expanding ](https://developers.swell.is/backend-api/querying/expanding)for more details.
- `fields` (string): Return only the specified fields in the result. For example `fields=name,slug` would return only the fields `name` and `slug` in the response. Supports nested object and array fields using dot-notation, for example, `items.product_id`. The category `id` is always returned.
- `include` (string): Include one or more arbitrary queries in the response, possibly related to the main query.

  See [including ](https://developers.swell.is/backend-api/querying/including)for more details.
