Need to debug json code

I am looking for a skilled developer who can help me debug a JSON code for a specific API integration that is not working. The code is less than 100 lines long. I just need someone to look into the code, because I need a second opinion, that I have done everything properly and the server has some problem.

Requirements:
- Strong experience with JSON and API integrations
- Proficient in debugging and troubleshooting code issues
- Familiarity with the specific API being used

Skills:
- JSON
- API integration
- Debugging and troubleshooting
