API Reference

API endpoints to manage the full lifecycle of your data and Basis Theory instance.

The Basis Theory API is organized around REST. Our API is built with a predictable resource-oriented structure, uses JSON-encoded requests and responses, follows standard HTTP verbs/responses, and uses industry standard authentication.

You are able to create different Tenants within your Basis Theory account to enable you to segment your test environments from your core production data. Tenants serve as a logical grouping for each of your systems to interact with Basis Theory without affecting each other.
