Backend SDKs
Frame ships official server-side libraries for calling the API from your backend. Each SDK wraps the same REST surface documented under API reference; the choice is language fit, not feature parity.
Use a backend SDK to keep your secret key off the client, sign requests, and avoid hand-rolling HTTP plumbing. For browser-side card tokenization and element rendering, use Frame.js instead.
Available SDKs
Frame Node SDK
TypeScript-first client for Node.js backends.
Frame PHP SDK
PHP client for Laravel, Symfony, and plain PHP backends.
Frame Ruby SDK
Ruby client for Rails and plain Ruby backends.
Reference
Each SDK's README documents installation, authentication, and per-method usage. Method signatures track the OpenAPI spec, so the generated API reference is the canonical surface for request and response shapes.
