Welcome to the RingCentral Community

Hey @Phong Vu

Thank you for the time, energy, and response! When you say a 'server-side' app, are you referring to the kind of application that I create in RingCentral Dev Portal? The Server/no ui option?

Would it be possible to change user presence status in the embeddable widget and have a custom 'User HUD Status' Salesforce field update accordingly? I'm new to Salesforce but I think that using the Streaming API to listen for user presence change events and then updating the custom SF field would be plausible. But where would I put the code telling Salesforce to listen for User Status Presence Changes? Where do I put the code that tells the RingCentral embeddble widget to emit User Status change events? Is the embeddable widget extensible to that degree? How does it get authorization to change a Users Salesforce Data?

Maybe you could point me in the right direction in regards to redirect url's; and why I'm unable to get a response when using cURL to submit requests.

I have thus far been unable to get a request to respond with anything other than an error. I've been trying to test my requests using cURL but I can't get an authorization token. The request I'm using (but with the account/password/clientid/clientsecret filled in appropriately) is from this medium article on using cURL to access the RC platform API.

Windows 10 Command Prompt uses the ^ for multiple lines so I use those instead of what is listed in the article "/".

curl -i -X POST "https://platform.devtest.ringcentral.com/restapi/oauth/token" ^
-H "Accept: application/json" ^
-H "Content-Type: application/x-www-form-urlencoded" ^
-u "<clientId>:<clientSecret>" ^
-d "username=<Account>&password=<password>&extension=&grant_type=password"

In Salesforce I have set up a Connected Application with two allowed callback URL's

https://apps.ringcentral.com/restapi/oauth/authorize?response_type=code&client_id=myClientID&redirect_uri=https://platform.ringcentral.com/restapi/v1.0/account/~/extension/~/presence&prompt=login_consent

But in response I get,

}

Maybe I have an error in my connected application callback URL? Maybe I'm sending my request to the wrong place? I am using my live RC credentials in the sandbox RC Server/no Ui application, could this be the issue? I am using my live credentials because the password field in the Sandbox is 'inactive'; can I set the password for my sandbox account?

Thank you!

Hi Thomas,

You can implement a server-side app to listen for user presence status changes at the account level then update user settings in Salesforce accordingly.

Please refer to these documentations for more info:

1. Webhook notifications quick start (change the event type with presence)

2. Presence information explained

Hope this helps!
