## Retrieve a Source

Retrieve a [Source](/api.md#sources) using its unique ID and client secret.

This method returns a `Promise` which resolves with a result object.
This object has either:

* `result.source`: a [Source](/api#sources) was retrieved successfully.
* `result.error`: there was an error.
  This includes client-side validation errors.
  Refer to the [API reference](/api/errors) for all possible errors.

**Syntax:** `stripe.retrieveSource(...)`

- `source` (object) **required**
  An object containing the unique ID and client secret for a `Source`.

You can use a `Source` object created with `stripe.createSource` as the argument to `stripe.retrieveSource`, as every `Source` object has both `id` and `client_secret` keys.

  - `id` (string) **required**
    Unique identifier of the `Source`.

  - `client_secret` (string) **required**
    A secret available to the web client that created the `Source`, for purposes of retrieving the `Source` later from that same client.

### Retrieve a Source

```js
stripe
  .retrieveSource({
    id: '{SOURCE_ID}',
    client_secret: '{SOURCE_CLIENT_SECRET}',
  })
  .then(function(result) {
    // Handle result.error or result.source
  });
```

```es_next
const {source, error} = await stripe.retrieveSource({
  id: '{{SOURCE_ID}}',
  client_secret: '{{SOURCE_CLIENT_SECRET}}',
});
```
