Integration Instructions

This section provides general guidelines and best practices for integrating with the GPAS system. Following these instructions will help ensure a smooth integration process.

Key Points to Consider

Parameter Case Sensitivity: Please note that all parameters are case sensitive.
Mandatory Parameters: All parameters are mandatory if they are not indicated as “Optional” in the argument tables.
JSON Format: The shipping format is in JSON. Always observe the examples given in each request.
Security: The Operator’s Account System must consider the security of communications and must always validate the signature of the message.
Appendices: Please review the appendices at the end of this document to avoid implementation errors.

Integration Process

Setup Security: Implement the security measures described in the Security section.
Implement API Methods: Implement all the required API methods as described in the Methods to Implement section.
Test Integration: Use the provided test environment to verify your implementation.
Validate Responses: Ensure your system provides the correct responses for all API calls.
Handle Errors: Implement proper error handling as described in the Error Response section.

Best Practices

Performance

Optimize your API endpoints for low latency responses
Implement caching where appropriate
Use connection pooling for database connections

Security

Always validate the signature of incoming messages
Implement proper authentication and authorization
Log all API calls for audit purposes

Error Handling

Provide clear and descriptive error messages
Implement proper exception handling
Return appropriate HTTP status codes

Testing

Test all API endpoints with valid and invalid inputs
Test error scenarios
Test performance under load
