In the three tier API structure, an application or business service API can be aligned with a vendor API by following these steps:

1. Understand the business needs: The first step is to understand the business needs and requirements. This includes the data that needs to be shared, the frequency of data exchange, and the expected results.

2. Identify the vendor API: Once the business needs are understood, the next step is to identify the vendor API that can provide the required data and services.

3. Analyze the vendor API: The next step is to analyze the vendor API and understand its capabilities and limitations. This includes the API documentation, usage policies, and the developer support provided by the vendor.

4. Develop the application or business service API: The next step is to develop the application or business service API that can interact with the vendor API. This includes the API endpoints, data models, and authentication mechanisms.

5. Test and deploy: After developing the APIs, it is important to test them rigorously to ensure that they function as expected. Once the APIs are tested and validated, they can be deployed in a production environment.

6. Monitor and maintain: Once the APIs are deployed, it is important to monitor them regularly for performance and security issues. Any issues should be addressed promptly to ensure the smooth functioning of the API integration.
