Build with Sendar's API
Sendar provides a RESTful API that lets developers integrate SMS, WhatsApp, and email messaging into any application. The API supports single and bulk message dispatch, real-time delivery webhooks, sender ID management, and contact list operations. Official SDKs are available for Python, Node.js, PHP, and Java, with a free sandbox environment for testing before going live on Nigerian carrier networks.
