Grow Payment Gateway (Meshulam)

Overview

Grow (formerly Meshulam) is one of Israel's leading payment gateways, powering thousands of businesses with credit card processing, Bit payments, Apple Pay, Google Pay, and more. Unlike other Israeli gateways, Grow offers a unified API (the "Light API") that covers payment pages, tokenization, recurring billing, payment links, invoices, and webhooks in a single integration.

This skill guides integration with Grow's Light API for the full payment lifecycle: accepting payments, saving tokens for recurring charges, creating payment links for invoices, processing refunds, and handling real-time webhook notifications.
