# Ronda > Recurring billing and payments for Armenian businesses — in dram, on local cards, through the business's own bank. A REST API (https://api.ronda.am), a hosted checkout on the bank's card page, signed webhooks, and a self-service customer portal. Integrating Ronda into a project: follow the playbook, then the references it points to. Never build a card form; keep the secret key server-side; start in test mode (sk_test_); verify webhook signatures. ## Guides - [Integration playbook](https://ronda.am/ai/integrate.md): the steps, in order, for any language - [API reference](https://ronda.am/ai/api.md): endpoints, fields, errors, idempotency, money in minor units (AMD: 1 = one dram) - [Webhooks](https://ronda.am/ai/webhooks.md): signature verification, event catalogue, event → user access - [Testing](https://ronda.am/ai/testing.md): test cards, 3-D Secure code, simulating renewals and recoveries, the proof checklist - [Going live](https://ronda.am/ai/go-live.md): what a business needs to take real money ## Optional - [Human docs](https://ronda.am/docs) - [Claude Code skill](https://ronda.am/ronda-skill.zip): the playbook plus a one-click account connection
