Salesforce Integration with Postman - The How-to Guide

Postman is an API advancement environment that is utilized to test an API, make and run robotized tests, look at reactions, and do much more stuff. As a Salesforce Developer or Admin, you can utilize mailman to test APIs and their reactions. In this way, how about we perceive how to arrange postman to test your APIs.

Create a Connected App

In Salesforce org, Go to SETUP and search App in Quick Find box and click on Connected App
Click on New and will see the New page to create a new connected app that shows the below:

Enter all required fields like Connected App Name, API Name, and Contact Email. I am utilizing Test Postman as the associated application name, the API name is naturally populated as Test_Postman and I have added my email id in the contact email field.

In API(Enable OAuth Settings) check the Enable OAuth Settings checkbox true.
This is very like when we make an associated application at any outsider worker which is utilized for a worker to worker correspondence, as we will utilize mailman so the Callback URL doesn't influence us. You can compose any URL there. It is essentially the URL where the approval code will be sent if there should be an occurrence of OAuth. I have utilized https://www.salesforce.com

Under the Selected OAuth Scopes area, pick Access and deal with your information (programming interface) and move it from the Available OAuth Scopes to the Selected OAuth Scopes segment. It is essentially a decision of which APIs you need to utilize like on the off chance that you need to utilize a jabber programming interface, you have to add it to the Selected OAuth Scopes area and comparative methodology for some other programming interface.

To get to standard Salesforce APIs to manage our information and for any custom APIs too that we make in peak, the Access and deal with your information (programming interface) is sufficient for us as I will utilize framework overseer certifications.

As should be obvious in the above picture, we have a Consumer Key and Consumer Secret which is available in the API (Enable OAuth Settings) segment. The shopper key will be obvious to you straightforwardly and for the customer, mystery clicks on Click to uncover connection and it'll be shown there.

The following stage is to get the entrance token. In case you're interfacing with your designer organization, use:- https://login.salesforce.com/administrations/oauth2/token as the URL to get the entrance token in any case, in case you're utilizing a sandbox, you can utilize https://test.salesforce.com/administrations/oauth2/token as the symbolic URL.

    "token_type": "Bearer",
    "issued_at": "<timestamp>",
    "signature": "<unique-signature-code>"
}

The occurrence URL is fundamentally the base URL of your organization. For Ex:- My occasion URL of engineer organization is:- https://ap5.salesforce.com/

You can investigate the REST API engineer control for standard APIs. Like now I have to inquiry, so I am ready to discover the documentation at - https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_query.htm
