Bandwidth Messaging API
Raleigh, North Carolina, United States
What it is
Bandwidth Messaging API sends SMS and MMS over HTTP for companies building messaging into their products. It supports two-way messaging, inbound webhooks, short codes, and toll-free numbers, with options that include 10DLC, alphanumeric, and global mobile number texting. Bandwidth lists messaging reach in 120+ countries. Traffic monitoring can show unregistered traffic and messages blocked by carriers or Bandwidth, with alerts by email or webhook. Registration Center can autofill customer and campaign information for Short Code and 10DLC; RCS is described as coming soon. Developer guides cover ServiceNow, Zendesk, and Salesforce integrations. New accounts have a default testing limit of one outbound message per second; A2P traffic can reach the account limit. Webhook deliveries without an HTTP 2xx response are retried multiple times over 24 hours, then stopped. Pricing is on request, and listed U.S. outbound rates range from free for 10DLC SMS to $0.02, paid once for MMS routes. A free trial is listed, but there is no free plan.
