# Custom Actions

The **Custom action** feature enables you to create and execute an HTTP request using your **OneSpan Sign** connection.

This action can be used to access any OneSpan Sign API endpoint that is not included in the prebuilt actions. The request will be automatically authorized with your OneSpan Sign connection, so you only need to specify the HTTP details.

For a list of available endpoints and payload structures, refer to the [OneSpan Sign API documentation](https://community.onespan.com/products/onespan-sign/sandbox).

## Input fields

| **Input field** | **Description** |
| --- | --- |
| Action name | Assign a descriptive name to this custom action, such as **Generate Signing URL** or **Send Transaction**. |
| Path | This is the path that will be added to the base URI of your OneSpan Sign connection (for example, if your base URI is `https://sandbox.esignlive.com/`, a sample path could be `/api/packages`). You can also provide an absolute URI to override the base URI. |
| Method | Select the HTTP method for the request: **GET**, **POST**, **PUT**, or **DELETE**. |
| Request type | Available for **POST/PUT/DELETE**. Choose the format for sending data in the request: **JSON**, **Raw JSON**, **Multipart form**, or **Plain text**. |
| Input | Available for **POST/PUT/DELETE**. Construct your request payload based on the **Request type** you selected (for instance, define the fields in the JSON body). |
| Request URL parameters | Available for **GET**. Set up query parameters to be added to the request URL. |
| Request headers | Include any headers required by the OneSpan Sign API, such as `"Content-Type: application/json"` or other custom headers. |
| Response type | Select how the response should be processed. Use **JSON response** if you want to extract output fields from a JSON body. |
| Response body | This is available when **JSON response** is selected. Specify the expected fields from the JSON response so they can be used as output fields. |
| Response headers | Optionally define the structure of any headers returned in the response if you wish to use them later. |

## Output fields

The output fields are determined by your **Response body** configuration. When the **Response type** is set to **JSON**, Workato will parse the response according to the **Response body** definition and make those fields available as structured outputs for use in your recipe.
