SDKs & tools
Official libraries for nine languages, a CLI and an MCP server. Every one speaks the same JSON API. Because the base URL is configurable, the exact same code runs against the CamelMailer cloud or your self-hosted instance.
Official SDKs
Each SDK reads a server API key (header X-Server-API-Key) and defaults to the cloud at https://app.camelmailer.com. Every one surfaces the API's stable error codes.
TypeScript-first, a { data, error } result on every call, zero runtime dependencies.
