Log in to RingCentral Developers

This connection authenticates on behalf of a registered application in RingCentral Developers.

If you do not have a RingCentral Developers account, you can register for one at [https://developers.ringcentral.com/sign-up](https://developers.ringcentral.com/sign-up)

  • Your account should have the Role Developer Admin

Create a New RingCentral Application

Register a new application that StackOne will authenticate through.

In RingCentral Developers, click the Console button, then Apps on the left.

Click the Register App button.

Under App Type, select REST API App (most common) and click the Next button.

Under App Properties (internal-use only), enter the following details:

  • App Name: Enter a name for your new App
  • App description: Enter a description for your new App
  • Primary Contact: Enter the email address of the main support contact for this App
  • Do you intend to promote this app in the RingCentral App Gallery?: No

Scroll down to the Auth section, and enter the following details:

  • Select 3-legged OAuth flow authorization code
  • From what type of app will you be calling the API?: Server-side web app (most common)
  • OAuth Redirect URI: `https://api.stackone.com/connect/oauth2/ringcentral/callback`
  • Issue refresh tokens?: Yes

Under Security, select the application permissions your integration needs, then choose who can access the app.

  • Application Scopes: select the permissions matching the actions you will use (e.g. ReadAccounts, ReadMessages, SMS, ReadCallLog, Contacts, TeamMessaging, RingOut, Faxes)
  • Who will be authorized to access your app?: This app is private and will only be callable using credentials from the same RingCentral account
  • Click the Create button to proceed. Upon seeing a success message, press the OK button.
  • Note: the StackOne connection test uses a permission-free RingCentral dictionary endpoint, so the connection will verify even with minimal permissions — but every action you intend to use still needs its application permission selected here, and permissions cannot be changed via the OAuth scope parameter later

Your new App Client ID and Client Secret will now be available to copy.

  • Under Production Credentials, copy both your Client ID and Client Secret and store them securely for use later
  • Note: application permissions are fixed at app registration — the OAuth scope parameter is ignored by RingCentral
## Creating the StackOne Connector Profile To create the Connector Profile in StackOne for RingCentral: Login to StackOne and navigate to [Connector Profiles](https://app.stackone.com/connector_profiles)
  • Click + Connector Profile
  • Search for and select RingCentral
  • Select Type as OAuth 2.0
  • Fill out the fields using details retrieved from your provider:
    • Client ID
    • Client Secret
    • Scopes (Optional)
  • (Optional) Select Actions to be enabled for this Connector Profile
  • Click Create profile
 Congratulations! The new Connector Profile will now show up in your project ready to be used. You can now continue to Link Accounts for RingCentral.
