A developer is creating an application that uses the Cisco Webex Teams API to send messages. What authentication method is typically used?
⚠ Common exam trap
Candidates often confuse API Keys with OAuth 2.0 tokens, assuming a simple key is sufficient, but Webex Teams requires the OAuth 2.0 flow for user-specific actions like sending messages, not just a static key.

Correct answer & explanation
✓
OAuth 2.0
The Cisco Webex Teams API uses OAuth 2.0 as its primary authentication method for applications that need to act on behalf of a user. OAuth 2.0 provides delegated access via access tokens, allowing the application to send messages without exposing user credentials. This is the standard for modern REST APIs that require secure, scoped access.
