Troubleshooting API Integration for Assistant Plugin Errors

Hello ! I have created a assistant plug with a dust app connected to my API with curl method. the curl call works fine when I run the test version in app but when I ask a question to this assistant I have an error. Is there a way to check if the correct API has been called with the correct parameter ? Or is there another way to be sure I've correctly plug my app to the agent ? Thank you for your answer 🙂
