How to make REST API calls using Leapwork?

Web services based on REST Architecture, commonly known as REST-ful Web Services use HTTP methods to implement the concept of REST architecture.  It can be used in a variety of messaging systems and can be delivered via a variety of transport protocols. Leapwork supports making the REST request using the HTTP Request building block.

Users can perform operations to Create/Read/Update/Delete data (CRUD operations) using REST API methods viz. POST/GET/PUT/DELETE requests. To perform REST API calls, the following four things are required in Leapwork.

• URL: Provide the REST endpoint as the URL.

• Headers: The Request Header contains metadata for the HTTP Request message as key-value pairs. For example, client (or browser) type, format supported by the client, format of the message body, cache settings, etc.

• Method: The HTTP methods most commonly used in a REST based architecture are as below. Choose one from these:

  • GET − Provides read-only access to a resource.

  • PUT − Used to create a new resource.

  • DELETE − Used to remove a resource.

  • POST − Used to update an existing resource or create a new resource.

• Body: In the request body, Message content or Resource representation can be specified.

Please see below an example of an HTTP Request block with various fields populated.
