Sendlyy provides organization-scoped REST APIs for dedicated WhatsApp messaging, shared verification codes, shared transactional notifications, contacts, usage and signed delivery events. Use an independent service key from your server. Sendlyy handles durable acceptance, tenant routing, provider delivery work and prepaid wallet accounting. AI agents are a separate dashboard offering; there is no developer AI or embedding API.

Implementation is distinct from service availability. Shared live products need Meta approval, reviewed templates, approved prices and explicit enablement. See availability before making launch commitments.
The base URL is https://api.sendlyy.app/api/v1. Routes are lowercase and multiword segments use kebab-case. Requests and responses use camelCase JSON. Use only the version actually deployed in your testing environment.
