Xrm.WebAPI with Promise for synchronous calls in Javascript

https://ecellorscrm.files.wordpress.com/2023/04/js-promise.png

Hi Folks,

Here is how I have quickly achieved the synchronous Retrieve multiple call using Web API and Promises with the help of JavaScript. I don’t want to make my post too detail, but I would like to share the approach.

All I want to do is to just Restrict saving the Contact creation if the Postal Code entered is not present in the system. But this call should be synchronous as the message should be shown immediately incase postal code is not found in the system and prevent saving the contact record. All you need to do is simple, just call the below function on change of Postal Code in Contacts.

Here in place of XMLHTTPRequest, I have used Xrm.WebAPI so that it won’t show a critial warning in Solution Checker.
