Request MaxioAbout the Maxio integration
Maxio (formed from Chargify and SaaSOptics) is billing and financial operations software for B2B SaaS companies. The Unify Payments API reads its customers, subscriptions, products, invoices and payments.
Maxio Advanced Billing (formerly Chargify) offers a REST API with API keys per site and webhooks for subscription and invoice events. The Unify Payments API maps customers, subscriptions, products and price points, invoices and payments to the Unify Graph.

Why build Maxio on Unify Int
One data model
Maxio records arrive in the same Unify Graph shape as every other platform in the category, with the original record kept in raw.
Unify Connect
A white-label flow for your customers to authorize Maxio. Tokens are stored and refreshed for you.
Custom fields and passthrough
Map Maxio custom fields per connection, and call any endpoint the model does not cover through passthrough requests.
Unify Monitor
Request logs, sync health and alerts for every Maxio connection, so support can see what happened.
