PayPal

PayPal is the second-most-common B2C payment method internationally,
after cards. The payments app ships PayPal Settings for both
Express Checkout and standard PayPal payments.

When to use it

• Global B2C — customers outside the EU often default to PayPal.
• Quick refund path — PayPal refunds are typically faster than
  card refunds.
• Buyer protection — some customers will only pay if they can
  use PayPal's buyer-protection scheme.

For Dutch B2C, iDEAL via Mollie dominates;
PayPal is a useful secondary option.

Settings

Open PayPal Settings in the awesomebar. Required:

• API username, API password, Signature — from your
  PayPal developer dashboard.
• PayPal Sandbox toggle — flip for test mode.

You'll also need to set up an IPN listener URL in PayPal's portal
pointing to ERPNext's webhook endpoint.

Workflow

Customer clicks pay link → PayPal Express Checkout → customer
approves → PayPal IPN fires → ERPNext creates Payment Entry.

Prilk support

Same as Stripe — upstream-maintained by Frappe, we treat it as
standard ERPNext functionality.
