Read these API docs and fill in my integration config

I am integrating with [API or service name] and need the exact configuration details. What I am trying to do: [describe the integration, e.g. create a customer then subscribe them to a plan]. What I have so far: [paste your config or the fields you are missing]. The docs: [docs URL, or find the official ones]. Read the documentation and fill in the blanks with exact values: endpoint URLs and methods, required versus optional fields with their precise names and types, the auth header format, pagination or rate-limit rules that affect my use case, and any webhooks or callback URLs involved. Quote field names exactly as the docs spell them — no paraphrasing. Include a complete example request payload and the expected response shape. Flag anything deprecated, and link each answer to the specific docs page it came from.
