Authentication uses API keys for REST API access. Maxio's API supports both site-level API keys and customer-specific tokens for portal integrations. Server-side integration should use the site API key with appropriate access scope. Teams should treat Maxio API keys with the security standards appropriate for billing infrastructure.
Maxio is the merged entity of Chargify (subscription billing) and SaaSOptics (revenue recognition), targeting B2B SaaS companies with complex billing requirements. The combined platform handles subscription lifecycle management, metered/usage-based billing, contract management, invoicing, and revenue recognition in a single product. For agents managing B2B SaaS billing workflows, Maxio's API covers the full subscription billing lifecycle — from creating subscriptions and processing upgrades/downgrades to generating invoices and managing dunning workflows.
The API covers subscriptions, customers, products, components (metered billing), invoices, and transactions. The component-based metered billing is particularly relevant for usage-based pricing models — agents can record usage events that feed into automated billing calculations. The subscription lifecycle API handles plan changes, trials, pauses, and cancellations with appropriate proration handling.
Reliability is appropriate for production billing infrastructure. Billing operations have direct revenue impact — agents triggering subscription changes, usage records, or invoice generation should implement appropriate error handling and idempotency to prevent duplicate billing events. Maxio maintains the availability required for B2B subscription management.
Documentation covers the REST API with comprehensive reference documentation and practical guides for common billing workflows. The metered billing documentation is particularly thorough for teams implementing usage-based pricing. Teams evaluating Maxio versus Chargebee or Recurly for B2B SaaS billing automation should compare the specific pricing model support for their subscription structure.
