Setting Up OAuth 2.0 Authentication

To connect your Twilio account to StackOne using OAuth 2.0, you will need to create an OAuth app and configure the appropriate permissions in the Twilio Console.

Open the Twilio Console and sign in with your account credentials. On the Dashboard, you will find your Account SID under the Account Info section.

From the Twilio Console, navigate to the OAuth Apps management page.

  • Open the Account management page from the Admin dropdown in the top-right corner
  • Select OAuth apps under Keys & Credentials in the left sidebar
Enables actions: Create Event Sink, Create Event Subscription, Create Message, Delete Event Sink, Delete Event Subscription, Delete Message, Get Account, Get Event Sink, Get Event Subscription, Get Event Type, Get Message, List Accounts, List Calls, List Event Sinks, List Event Subscriptions, List Event Types, List Messages, List Subscribed Events, Make Call, Update Message

Create a dedicated OAuth app for the StackOne integration. The minimum required scope to link the account is messaging.messages:list.

  • Click + Create an OAuth app
  • Enter an app name (e.g., StackOne Integration) and a description, then click Next
  • Select the OAuth scopes listed above
  • Click Create app to generate your credentials (Client ID and Client Secret)
  • Tick the box to confirm you have securely stored the Client Secret, then click Finish

Linking the Account from the Hub

Use one of the three Linking Account Methods to access the Hub. Fill out the following fields using details from your provider:
  • Region
  • Client ID
  • Client Secret
  • Account SID
  • Click Connect
  • If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider's authorization flow.
  • Once authorization is successful, you will see a confirmation popup

If the account linking is successful, you will see the newly linked account in your Accounts page.
