# Retrieve an invoice line

> Returns one line of an invoice.

Fetches a line under `invoice.line`. To find a specific line, use the lines endpoint.

> [!NOTE]
>
> The SDK samples get their client from credentials your app registers once when it starts, as shown in [Authentication](https://exsited.mintlify.site/authentication.md#set-up-a-client). To try the call here, click **Try it**, set `host` to your Exsited API host name and paste an access token from [Get an access token](https://exsited.mintlify.site/api-reference/authentication/get-an-access-token.md).
