Worked on the algolia/api-clients-automation repository to deliver Version 3 of the A/B Testing API specifications, focusing on enabling advanced experimentation workflows. The work involved designing new schemas, parameters, and endpoint paths using TypeScript and YAML, allowing for more granular control and detailed reporting of A/B tests. Specification development was aligned with repository standards, ensuring smooth integration with downstream SDKs and preparing comprehensive documentation for release. The update was implemented through a focused schema and endpoint revision, supporting richer experimentation capabilities and improving the quality of test data and decision-making processes for users of the API and related tools.
