Burner supports voice calls, SMS and MMS over VoIP/PSTN, with spam blocking, voicemail transcription, auto-reply and multi-line management. For developers, Burner exposes an OAuth 2.0 REST API (api.burnerapp.com) for programmatic line management and messaging, a webhook system for real-time event notifications, and the open-source Burner App Starter Kit (BASK) for building Burner-integrated apps and bots such as Hostbot and Ghostbot.

Burner publishes 1 API on the APIs.io network. Tagged areas include Company, Phone Numbers, SMS, MMS, and Voice.

The Burner catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Burner’s developer surface includes documentation, engineering blog, pricing, support, authentication, and 15 more developer resources.
