Bandwidth Messaging API

The Bandwidth Messaging API allows developers to send and receive SMS and MMS messages programmatically. It supports both toll-free and local number messaging, group messaging, and application-to-person (A2P) messaging workflows. The API provides delivery receipts via webhooks, message status tracking, and media management for MMS attachments. Bandwidth operates its own tier-1 network, providing direct carrier connectivity for reliable message delivery.
