# Integration Guide

> Reference material for the REST surface, outbound webhooks, and single sign-on.

## Using this guide

The guide is written for developers integrating RIKAISO with an existing landscape. It assumes you can issue HTTPS requests, verify HMAC signatures, and configure an identity provider.

Every interface described here is versioned. Breaking changes are shipped in a new version segment, never in place.

## In this section

- [REST API Overview](https://help.rikaiso.com/2026.1/rest-api-overview.md): Base URLs, authentication, pagination, error shape, and versioning for the RIKAISO REST surface.
- [Webhooks](https://help.rikaiso.com/2026.1/webhooks.md): Subscribing to RIKAISO events, the payload format, signature verification, and retries.
- [Single Sign-On](https://help.rikaiso.com/2026.1/single-sign-on.md): Configuring SAML 2.0 or OpenID Connect for a RIKAISO tenant.
