Cant create the production key

Which endpoint / permission is the Status & Review section for your application saying you have not utilized please? (a screenshot of API Permissions Analytics and Status & Review page if you have them)

According to the Analytics for your application, you have not executed any API requests which are associated with the various API Permissions you have set on your application. I only see OAuth API requests (which do not count towards the total of required API requests needed for your application to be enabled to "Apply for Production").

If you click the "Edit Permissions" link in the Status & Review section of your application (this is next to the item labeled "Exercise all requested permissions"), you should see the list of API permissions you need to exercise.

You can use the API Developer Guide to view the various API routes which map to the various API permissions you have enabled for your application: https://developers.ringcentral.com/api-docs/latest/index.html

Let me know if you have further questions.

Hi I m just reading the caller id using the presence event and I have actually tried it but just giving the premissions for presence event, but it did not work. So I select all the permission but results are same. I really don't understand how to get over it.

If you just want to watch presence events for extensions to obtain the callerID for calls, you will need the following API permissions:

1. ReadPresence
2. ReadAccounts

I have created a sample application which shows how to subscribe to presence events here: https://github.com/bdeanindy/ringcentral-subscription-basics

The above code uses the RingCentral JS SDK. I highly recommend using one of the RingCentral SDKs to create and manage your subscriptions if it is available in your language of choice. https://github.com/ringcentral

You will need to create (API POST request) the Subscription, add your event filters (see the above code for an example, and the full docs here: https://developers.ringcentral.com/api-docs/latest/index.html#!#RefCreateSubscription), then register your subscription. You can then test if things are working (make sure you are logged into the softphone of a user) by dialing from your cellular device into the Extension you are monitoring for Presence events as defined in the eventFilters for the Subscription.
