"GET_REST_VALUE" Command
Description: This command retrieves a value from the response received from a call to a REST end point which can be used anywhere in your test case.
Usage Scenario: Suppose we want to get some information from the response about a profile by entering its ID number.
Procedure: Define a step with Get_Rest_Value which contains exactly which data you are trying to retrieve in JSON. For exmaple, to retrieve the first name of a user, we can use "firstName”. To identify which user the request is sent for, you can use a variable to store the user ID in a Set_Var step which starts before Get_Rest_Value step. The same variable name needs to be in the REST Connection URL field.
REST Connection URL example where @id uses a variable defined in a Set_Var step
Your steps will look like this:
