When designing an API — what exactly could you not do alone, who did you ask?

When designing APIs, there are often challenges that are difficult to solve alone, such as:

• Defining requirements and usage scenarios for the API, especially when considering different business processes.
• Choosing architectural solutions and standards (REST, GraphQL, gRPC).
• Discussing security and authentication issues.
• Agreeing on data formats and API versioning.

In such cases, I turn to:

• Business analysts to clarify requirements and usage scenarios.
• System architects to select the right technical solutions.
• Security team to agree on access policies.
• Colleagues-developers to discuss technical details and best practices.

For example, when choosing the response format for the API, I consulted with frontend developers to ensure convenience and performance on the client side.
