I'm working on building the application on the salesforce marketing cloud and facing the issue of making POST /login call to application.
Scenario: We have created a cloud application in Installed package, and given the login and logout URL of our application which is hosted on our server. Now to get the organization ID, /login page will make POST call. But when I do the POST call, I'm getting error. I want to get organization ID here. can someone help me here.
Once I setup the application, I am making POST call to the Marketing cloud application URL using POSTMAN, and receving 200 ok as HTTP response but unable to find organisation ID.
First Image shows the POST call to the cloud application. Second image shows the application setup.
