10 things to do before you release your API

Releasing an API requires careful preparation to avoid issues such as increased support, downtime, or customer dissatisfaction, and a checklist of ten important steps can help ensure a smooth launch. Key actions include verifying that the API meets stakeholder needs by involving all relevant parties in the design process, offering a preview release for stakeholder feedback, and identifying any potential breaking changes to minimize disruption for API consumers. A thorough security review is crucial, especially when handling sensitive data, to prevent exposure risks. Updating API documentation, examples, and guides ensures clarity and usability for developers, while a detailed changelog communicates enhancements and changes to stakeholders without revealing sensitive implementation details. Additionally, updating API management layer configurations and verifying that the API release aligns with the published design contract through automated tests are essential steps. Comprehensive testing, including unit, functional, and acceptance tests, is necessary to ensure the API supports its intended use cases. Finally, drafting an announcement with the changelog and other release details helps generate interest and demonstrates ongoing API improvements.
