A developer wants to send an outbound message when a record meets a specific criteria.

Flow Builder:

Flow Builder can evaluate record criteria using a Decision element and then send an outbound message using the "Action" element.

Allows automation without Apex.

Approval Process:

Approval Processes can evaluate criteria and trigger outbound messages as one of the associated actions.

Why Not Other Options?

C. Entitlement Process: Focuses on managing entitlements, not triggering outbound messages.

D. Next Best Action: Used for recommendations and guided actions, not for triggering outbound messages.
