How to make a GraphQL API call using Postman
A step by step tutorial on making a GraphQL call in Postman.
The following tutorial makes use of the free Pokemon API (PokeAPI), which is a free RESTful Pokémon API, that uses GraphQL to process requests. We use the GraphQL documentation provided at this link to construct a tutorial for you to learn how to make GraphQL calls using Postman.
Step One: Determine your Query
Navigate to the PokeAPI GraphiQL and plug in your query and use the Explorer to create a query which will appear under the Play sign next to GraphiQL.
For the purposes of this tutorial, we have made the query available below.
Step Two: Determine the Request Headers
Select Request Headers under Post to discover the API request headers required for the call.
Step Three: Navigate to Postman
Go to Postman, sign in and select Create New under Start with something new.
Step Four: Select HTTP Request Building Block
In the modal that appears, select HTTP Request.
Step Five: Setup your call and headers
As demonstrated in the image above, update your Postman HTTP request to match that of Step 2.
Step Six: Declare the body
Click on Body and select GraphQL.
Then paste in your GraphQL query under Query as gathered from the PokeAPI GraphiQL.
Step Seven: Send
Click Send and see the GraphQL results at the bottom of the screen.
