Create a WhatsApp template

Submit a new message template for WhatsApp's review in a channel's business account: name, language, category (marketing or utility), body, and optional header, footer and buttons. The header is a fixed text, or a document (PDF), image or video with a sample file in base64 (up to 5 MiB) for the review; each send then carries its own file. It stays pending until WhatsApp approves or rejects it, usually within minutes, and WhatsApp may change its category. Check the result with list_templates; a rejected template explains why in rejectedReason.

Scope: raiz:templates:write
Credentials: an API key, a client-credentials token or a person's access token
Effect: writes; not idempotent: check the outcome before you retry
Limits: request body up to 8 MB, response up to 1 MB
CLI: arbol raiz templates create · MCP tool: raiz_templates_create
