OneGate's A2A interface allows automated submission of regulatory reports without manual portal interaction. This guide covers the technical implementation for integrating your systems with OneGate.

Key Takeaways

  • A2A enables automated, scheduled submissions
  • Certificate authentication is still required
  • Web services use SOAP or REST protocols
  • Response handling must be implemented
  • Testing in sandbox recommended before production

A2A Overview

Implementation Steps

Implementation roadmap: 1. Request A2A access from BdF 2. Obtain technical certificate 3. Configure IP whitelisting 4. Develop web service client 5. Test in sandbox environment 6. Validate response handling 7. Move to production

Error Handling

Handle A2A responses: • HTTP errors: Network/connectivity issues • SOAP faults: Service-level errors • Business errors: Validation failures • Timeout handling: Retry logic Implement robust error handling and alerting.

Checklist

  • A2A access requested and approved
  • Technical certificate obtained
  • IP addresses whitelisted
