When iam trying to update user information iam not able to update.
Please provide more information on the error you've received by sending the response request of the error received, screenshot and the Correlation ID. From there, I'll help look into the error and work with you to resolve the problem.
Below are the steps to get the Correlation ID using a Google Chrome browser.
1>Open Chrome menu.
2>Click on More tools then Developer tools.
3>Check the box to Preserve Log for the Network Tab.
4>Then try to click on the add API link.
5>You can find the Correlation ID in the network log for add API call.
! We're going to have a front-end JS SDK so you can do just that.
At the moment I'd recommend that you still have a teeny little server and perform API calls from there, I've written a sample Node.js (express) app in ~100 lines of JS which handles signups, logins, sessions etc.
And yes, he is rather a fine gentleman isn't he.
