Integration guides

Place your first call with the API

This guide shows how to trigger an outbound call with the demo voice API and follow its state. Everything is fictional: the call is simulated until a provider is configured.

Send your first SMS with the API

This guide shows how to send an SMS with the demo API, read the segments and encoding, then follow the statuses. The SMS is simulated until a provider is configured.

Manage your numbers with the API

This guide covers three actions: search for an available number, order it for a project, then list your numbers. The order is simulated until a provider is configured.

Read your usage

This guide shows how to read the quantities used by day, number, project, country or service. The figures in the example are fictional and carry no amount.

This guide explains how to authenticate an event received by webhook: reading the header, computing the signature, constant-time comparison, tolerance check and deduplication. Fictional Node.js example.

Prepare a number port

This guide is a preparation checklist, not an official procedure. It helps you gather what you need before describing your request in a quote request.
