How to connect Salesforce with Postman

It is pretty easy to connect Salesforce API with the postman
First, you need to have access to developer org, or you can try it out in your trailhead playground.

I will use the Trailhead Playground because it already has pre-installed packages.

  • Sign in to your trailhead account.
  • Go to this article, scroll down, click launch, and create your trailhead playground.
  • After that, click “ Get your Login Credentials” in the nav bar and reset your password.
  • Go to your trailhead playground and go to setup and Search for CORS.
  • Add two entries to the allowed origin list https://*.postman.co, and another for https://*.postman.com.
  • After that, Go to Postman and create a new workspace.
  • Set visibility to Personal
  • After that, go to the Explore and Search Salesforce Platform APIs.
  • There are two ways to fork APIs. You can do it directly or hover over the three dots and create a fork.
  • Hover over the three dots, select create, and save it as a Salesforce API Fork.
  • Go to your collection, and under Authorisation, scroll down to “Get New Access token.”
  •  Sign in and Allow
  • Once authentication is complete, you will get a popup. Click Proceed
  • Copy the instance URL and click “Use token.”
  • Go to the Variable, scroll to the endpoint, paste the instance URL, and Save.
  • Let’s see if it is working.
  • Go to the Bulk v2 and click the dropdown and select the query
  • Click the dropdown once again and Click Create Job Query
  • Make changes in the body
				
					{
"operation" : "query",
"query" : "SELECT id , name FROM Account",
"contentType" : "CSV",
"columnDelimiter" : "COMMA",
"lineEnding" : "CRLF"
}

 

  • Click Send
  • After that, go to the Get Job info query and click Send
  • Check if the ids are the same
  • And After that, you can Get Job Query Result and see all the accounts
  • You can cross-check it in your org. Go to the account and see all the records

That’s it, and that’s how you can use Postman to make requests to the Salesforce API and perform various tasks within your Salesforce account.
