Decoupling content from the codebase using APIs has transformed project velocity by allowing teams to harness specialists' domain expertise, find people with the right skills, and enjoy internationalization, tool flexibility, and omnichannel support. By separating content management and presentation logic, developers can focus on their primary purpose while leveraging external tools and services for content management, optimization, and availability. This approach also enables easier workflows and permissions, reduced complexity, and increased confidence in project outcomes. However, managing multiple APIs still poses a challenge, which can be addressed by using tools like Netlify Connect to aggregate, normalize, and simplify API usage.
