You are building an Azure Logic App that needs to call an external HTTP API secured with OAuth 2.0 Client Credentials flow. The client ID and client secret are stored in Azure Key Vault. You need to obtain an access token and include it in the Authorization header of each request. Which combination of actions should you use within the Logic App?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Use an HTTP action with the OAuth 2.0 authentication type. Set the client secret parameter to a secure reference to the Key Vault secret.
Logic Apps' built-in OAuth 2.0 authentication for HTTP actions handles token acquisition and renewal. The secret can be securely referenced from Key Vault via a parameter.
B
Distractor review
Use two HTTP actions: first, call the token endpoint with credentials to get a token, then use the token in the second action. Store credentials in a string variable.
This approach is more complex and less secure. Storing credentials in a variable exposes them in the workflow definition. The built-in OAuth 2.0 authentication abstracts token management.
C
Distractor review
Use the HTTP action with managed identity authentication.
Managed identity is used to authenticate to Microsoft Entra ID resources, not to third-party APIs that require OAuth 2.0 Client Credentials with a specific client ID and secret.
D
Distractor review
Use the 'Invoke an Microsoft Entra ID protected API' connector with the client credentials grant type.
This connector is designed for APIs protected by Microsoft Entra ID. If the external API is not registered in the same Microsoft Entra ID tenant or does not use Microsoft Entra ID, this connector may not work.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this AZ-204 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Use an HTTP action with the OAuth 2.0 authentication type. Set the client secret parameter to a secure reference to the Key Vault secret. — The HTTP action in Logic Apps supports OAuth 2.0 authentication. When you configure the HTTP action, you can select 'OAuth 2.0' and specify the token endpoint, client ID, and client secret. The client secret value can be referenced securely using Key Vault references in the parameters. Logic Apps handles token acquisition and token refresh automatically. Using a separate 'HTTP' action to call the token endpoint is unnecessary and less secure.
