Automating POST and PUT Request Using Rest Assured

In the previous blog, we already have seen how to Automate GET and Delete Request using Rest Assured. In this blog, we would be looking into how to automate POST and PUT Requests.

In this example, I would be continuing with the same website https://reqres.in/ which we are using in our previous blogs.

As we already discussed in order to use Rest Assured effectively we need to do some static import manually in our IDE.

import static io.restassured.RestAssured.given;

import static org.hamcrest.Matchers.equalTo;

While working with POST and PUT Request we need to pass the JSON body along with Authorization Key (if applicable) and Header.

Let’s now start with POST Request.

As shown in the below screenshot once we fire the POST Request to Server it will respond back with status Code 201 which means the request is created on the server along with the JSON response body.

In this case, our Base URI is: https://reqres.in/ and successive URI for passing POST request is “/api/users”

Now let’s fire the same request in Postman and validate the response Header along with Body of the JSON Response.

As we can see in the above screenshot we are getting the same response along with some additional details which will ultimately help us to validate different scenarios while doing API Testing.

As we discussed already while working with POST and PUT request we need to pass the Body in JSON  Request Format. Please use this link to convert JSON Body into that specific format.


Below is the code for creating the list of the user. In this code for validating any specific response in the Header, we need to use a header of the JSON Body we got in postman response.

Below is the output after Code execution.

Similarly, we can use below PUT request which will respond back with status code 200.
