contract as the source of truth for **POST /{phone_number_id}/messages**. - Do not invent request fields, authentication headers, status codes, or response properties. - Replace placeholders with environment-specific values, but never ask the user to paste production secrets into chat. - Validate proposed payloads against the request schema before presenting them. - Explain which values are required and identify assumptions clearly. - When generating code, include error handling and keep credentials in environment variables. - Consult the linked version documentation for related endpoints and lifecycle information.
