Correct answer & explanation
✓
Register an application in Microsoft Entra ID and configure the custom connector with the client ID and secret
Custom connectors with OAuth 2.0 require registering the app in Microsoft Entra ID. Option A is not possible. Option B is for custom API, not authentication. Option C is for API key authentication, not OAuth.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Select 'OAuth 2.0' as the authentication type and enter the API key
Why it's wrong here
OAuth 2.0 does not use API keys; it uses tokens.
- ✗
Create the connector with a Swagger file and set authentication to 'Anonymous'
Why it's wrong here
Anonymous is not secure for external APIs.
- ✗
Use the built-in HTTP connector with Basic authentication
Why it's wrong here
Basic authentication is not OAuth 2.0.
- ✓
Register an application in Microsoft Entra ID and configure the custom connector with the client ID and secret
Why this is correct
OAuth 2.0 requires app registration and credentials.

Same concept, more angles
1 more way this is tested on PL-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A developer builds a canvas app that uses a custom connector to call an external API. The API requires an OAuth 2.0 client credentials flow. Which authentication type should the developer configure in the custom connector?
hard- ✓ A.OAuth 2.0
- B.Windows Authentication
- C.API Key
- D.Basic Authentication
Why A: OAuth 2.0 client credentials flow is a standard OAuth flow used for server-to-server authentication where no user is involved. Option B is incorrect because Windows Authentication is not OAuth-based and does not support client credentials flow. Option C is incorrect because API Key is a simple token-based authentication, not OAuth. Option D is incorrect because Basic Authentication sends credentials in plaintext and is not OAuth 2.0.
