 Make a callout to the payment gateway through ESB supporting error handling and logging for audit purposes. This solution meets the requirements of integrating with an external RESTful service, ensuring real-time updates to the CSR, and supporting post payment processes. ESB stands for Enterprise Service Bus, which is a software architecture model that allows communication between different applications via a common bus. ESB can handle the callout to the payment gateway service, and provide error handling, logging, routing, transformation,and orchestration capabilities. ESB can also integrate with other systems or services that are involved in the post payment processes, such as billing, invoicing, or reporting.

Handle verification process error in the Verification Webservice API in case there is a connection issue to the Webservice or if it responds with an error. This solution ensures that the agent can see an error message when the credit verification process failed, and take appropriate actions. The Verification Webservice API can implementerror handling logic to catch anyexceptions or errors that occur during the callout to the external agencies, and return a meaningful error message to the agent. The agent can then retry the verification process, or escalate the issue to a supervisor. References: Certification - Integration Architect - Trailhead, [Apex Web Services and Callouts]
