  title: Basis Theory 3D Secure Reactors API
  description: The Basis Theory API is a PCI Level 1 compliant tokenization and data vault platform. It lets developers tokenize, store, and use sensitive data - cardholder data, PII, PHI, and bank account numbers - without that data touching their own systems. The API exposes Tokens, batch Tokenize / Detokenize, Applications, the detokenizing Proxy (pre-configured and ephemeral), serverless Reactors, 3D Secure, Tenants, Logs, and Webhooks. All requests are authenticated with a `BT-API-KEY` request header.
