Sharepoint Integration using Postman

I wanted to try out Sharepoint integration with Postman. So, I was following the steps given in the below article: https://medium.com/@anoopt/accessing-sharepoint-data-using-postman-sharepoint-rest-api-76b70630bcbf. I followed all the steps exactly as to how it is mentioned in the article. So I created the following:

• Environment with key value pairs Environmental Variable
• Used the URL provided below:

https://accounts.accesscontrol.windows.net//tokens/OAuth/2  

• Entered the key value pairs in body and javascript in Test and clicked on Send.

  When I click on Send, I am getting the below error: Error

    {"error":"invalid_request","error_description":"AADSTS900023: Specified tenant identifier '' is neither a valid DNS name, nor a valid external domain.\r\nTrace ID: af51e70f-4f1d-4b25-8112-d800d1a2e600\r\nCorrelation ID: d92a6863-6cba-4c84-8569-135bfabbaf91\r\nTimestamp: 2021-02-05 03:04:37Z","error_codes":[900023],"timestamp":"2021-02-05 03:04:37Z","trace_id":"af51e70f-4f1d-4b25-8112-d800d1a2e600","correlation_id":"d92a6863-6cba-4c84-8569-135bfabbaf91","error_uri":"https://accounts.accesscontrol.windows.net/error?code=900023"}
