Integration with the new service does not exist yet — it needs to be developed. How does this change the approach?

If integration with a new service does not yet exist and needs to be developed, the approach changes as follows:

• Conduct a detailed analysis of the requirements and capabilities of the new service, including studying APIs, protocols, and data formats.
• Design the integration architecture, considering the features of the service and requirements for security, performance, and fault tolerance.
• Identify interaction points, authentication methods, and error handling.
• Develop and test a prototype or a minimally viable product (MVP) of the integration.
• Implement monitoring and logging to track the operation of the integration in production.

Thus, the approach becomes more exploratory and project-oriented, requiring close collaboration with the team responsible for the new service and careful planning of development stages.
