Basic REST request to SharePoint using Postman

I wanted to share this tutorial on how to consume SharePoint’s REST service using the HTTP client Postman. I have to do this on a daily basis but keep forgetting the details and have to Google it, but Google is not that helpful and I get results that are unnecessarily complex.

I’m using a development environment and am logged in as a user with permission to read the data I’m requesting, which is a requirement. It takes to steps, first we have to prove that Postman is authenticated and then we can request the data.

Getting authenticated

Type in

into the input field and make sure it’s a POST-request. Now we need to add a header, to tell SharePoint what kind of data we want back, so click on the ”Headers” button at the top right corner. At the left side on the new lines that appear, enter Accept. At the right side enter application/json; odata=verbose. It should now look something like this:

rest-1

Then click send and you get the results back. Copy the FormDigestValue, which is a really long string ending with a date and time. Mine looked like this:

Getting data

Change the URL to, for example,

and it should still be a POST-request. The accept-header should look the same, but now you need to add the FormDigestValue as another header. To the left, enter X-RequestDigest and to the right enter the value you copied before. Then all you have to do is click send, and the data appears. The finished result:
