# Payments Library Credentials

> Generate and manage API credentials for PCI Booking's client-side JavaScript Payments Library.

The [Payments Library](/payments-library/overview) supports multiple payment methods beyond card payments. Each method requires you to set up credentials with the payment provider and store them in PCI Booking.

## How It Works

1. **Set up an account** with the payment provider (Apple, Google, PayPal, etc.).
2. **Obtain credentials** from the provider (API keys, merchant IDs, certificates).
3. **Store credentials** in the PCI Booking portal as an eWallet account.
4. **Reference the stored account** when initializing the Payments Library in your checkout page.
