AuthKit Remix SDK

Installation

Install the SDK with your package manager, then read the API key from the environment rather than hard-coding it.

1npm install @paycux/node

Usage

Usage is handled by AuthKit Remix SDK rather than by your application code. Paycux exposes it through the same API surface as the rest of the platform, so the client you already configured needs no additional setup.

Configuration lives in the dashboard and is versioned per environment. Change it in staging, confirm the behaviour, then apply the same change to production.

AuthKit Remix Library

Official SDKs are published for Node.js, Python, Ruby, Go, PHP, Java and .NET. They share the same method names, so a snippet translates between languages with little more than syntax changes.

Each SDK reads PAYCUX_API_KEY from the environment by default and retries idempotent requests on transport errors.

Customizing Session Storage

Paycux issues a sealed session cookie alongside the access token. The cookie carries no user data of its own — it is an encrypted pointer that the SDK unseals on each request using your cookie password.

Access tokens are short-lived by design. Refresh them on the server, never in the browser, and treat a failed refresh as a signal to send the user back through sign-in.
