Hello Team,
We want to implement calling functionality in our Application for that we have decided to use RingCentral for that first we need to check it in the demo application. We are using PHP Package.
Here are the details of our Demo Application.
Application Name: SAMI-Aid
Client ID: gyNTMqexxxxxxx
Client Secret: vU35UBKyxxxxx
Phone number: 1608729xxxx
Username:michaelsmith@samiaid.com
Application Type: Private
Platform Type: Server/Web
Permissions Needed : CallControl , RingOut, SMS, VoIP calling, ReadCallLog, SubscriptionWebhook
Now when I am trying to generate an access token using curl request I got an error like below
curl Request :
curl -X POST "https://developers.ringcentral.com" panel, It's working fine.
Please find Attachment
If you're using an OAuth 2.0 request using the OAuth 2.0 password grant (grant_type=password), then your application you created should in the RingCentral Developer Portal should be Password flow .
Please note, application created with different platform type will have different grant_type.
For example, application created for platform type = browser based will have grant_type=Authorization Code | Implicit | Refresh Access Token where as application for platform type = Desktop/Windows will have grant_type= Authorization Code | Password flow |Refresh Access Token
So in order to use (grant_type=password) you need to have application created with platform type that support Password flow
Here is wonderful way it has answered with animated Gif image that will easily help you to understand the proccess: https://stackoverflow.com/questions/47692828/ringcentral-auth-token-failed-in-curl-call-unauthorized-for-this-grant-type/47745436#47745436
Otherwise, if you want to use the password flow authentication, create a new app and select the Server-only (No UI) for the Platform Type. See this demo https://developers.ringcentral.com/guide/voice/quick-start/php
