# 6. Frequently Asked Questions

Q: How should I choose between the two integration methods? If you want to quickly verify Agent Builder's own capabilities and see the most raw interaction process, choose 4.1; if you are already using a platform like Copilot Studio and want to integrate Agent Builder as one of the callable agents into your existing environment, choose 4.2.

Q: Why is the wording of the replies different when asking the same question through the two methods? In 4.1 you see Agent Builder's raw reply without any processing; in 4.2 the language is reorganized again through Copilot Studio's own generative orchestration, which is the platform's expected behavior and does not indicate that either side is "in error".

Q: Does integration require additional development work? Methods like Copilot Studio require no coding at all — you just configure it on the interface; for custom Agent integration, if you use the SDK we provide, you only need to install dependencies, configure the .env, and start one command, with no additional development needed.

Q: How is data security ensured? Each call must carry your own API Key for identity authentication, and Agent Builder will only return data that the identity has permission to access.
