If your SMSGatewayCenter API integration isn’t working, follow these debugging steps:
Verify Credentials: Ensure your userid, password, or API key is correct and hasn’t expired. Regenerate your API key if needed via the portal under “API Key Settings.“
Check Parameters: Confirm all required parameters (e.g., senderid, mobile, msg) are included and properly formatted. Use URL encoding for special characters.
Review Response Codes: Check the API response for status codes (e.g., 200 for success, 401 for authentication failure). The response will include a reason field explaining errors—log this for analysis.
Test with Sample Scripts: Use our provided sample scripts (e.g., PHP CURL) to compare against your code. Start with a simple test message to a single number.
Inspect Network Requests: Ensure your HTTP request (GET/POST) to https://unify.smsgateway.center/SMSApi/send or other endpoints is correctly formatted and not blocked by firewalls.
Contact Support: If issues persist, reach out to our 24/7 support team with your API request details, response, and error logs for quick resolution.
