Worked on the codatio/codat-docs repository to deliver a focused update clarifying the API’s idempotency policy and improving related documentation. Addressed the handling of 429 Too Many Requests responses, specifying that these are not cached and can be safely retried with the same Idempotency-Key, which reduces client risk during automated retries. Enhanced the documentation to better guide developers on idempotency and rate-limited requests, ensuring alignment between system behavior and published guidance. The work involved technical writing and API design, utilizing Markdown to implement clear, actionable documentation changes. No bugs were fixed during this period, with efforts concentrated on feature delivery.
