[ API Reference ]

Build anything on Vomenta.

REST APIs, webhooks and real-time events for calls, messages, contacts, campaigns and analytics — plus embeddable chat and click-to-call widgets, and BYOK for AI.

Authentication

Authenticate with an API key

All requests are made over HTTPS to api.vomenta.com/v1 and authenticated with a bearer token. Generate keys in your dashboard and keep them server-side.

Core resources

Calls, messages & contacts

Create and manage calls, messages, contacts and campaigns. Every resource supports list, retrieve, create and update with consistent pagination and filtering.

Webhooks & events

Real-time events

Subscribe to events like call.completed and message.received. Vomenta signs every payload so you can verify authenticity.
