iOS 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

Add the Paycux iOS SDK to your app with Swift Package Manager

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.

Beta Versions

Beta Versions is handled by iOS 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.

Official Paycux iOS SDK

Official Paycux iOS SDK applies specifically to iOS SDK. It behaves the same in both environments, and the values it depends on are visible in the dashboard for the environment you have selected.

If the behaviour you see does not match this description, check which environment your API key belongs to before anything else — a staging key against production data is the most common cause.

Get started with Paycux

iOS SDK is part of the Paycux platform. This page explains what it does, when to reach for it, and the smallest working setup you can ship.

Everything below applies to both environments. Build and test in staging, then promote the same configuration to production without changing your code — only the API key and client ID differ.
