🔍 Tips for Debugging

• Always log the full request: method, endpoint, timestamp, and body.

• Ensure system clocks are synced to avoid timestamp-related errors.

• Verify the signature format and ordering match the API documentation exactly.

• Avoid high-frequency bursts that could trigger rate limit errors.
