CHIP for Gravity Forms

The official CHIP payment add-on for Gravity Forms. Accept payments seamlessly with Malaysia's leading payment methods including FPX, credit/debit cards, DuitNow QR, and e-wallets — for one-time payments and recurring subscriptions.

Features

• Native Gravity Forms integration - Add CHIP as a payment feed to any form
• Global and form-specific settings - Set Brand ID and Secret Key once globally or override per form
• Multiple payment methods - FPX, Credit/Debit Cards, DuitNow QR, E-Wallets, and more via CHIP hosted checkout
• Client data mapping - Map form fields to CHIP client metadata (e.g. legal_name, address, country)
• Subscriptions - Sell recurring plans with a recurring amount, billing cycle, optional trial, setup fee, and a limited number of installments
• Automatic renewals - CHIP charges the stored card on schedule; renewals run with no customer present
• Recovery and dunning - A failed renewal is retried on a 1, 3, and 5 day ladder, the customer is emailed a secure link to pay and update their card, and you can re-send that link from the admin
• Subscriptions list - See every subscription, its status, next payment date and retry count in one admin page
• Refund from entries - Process full refunds from Gravity Forms → Entries when enabled in settings
• Webhook support - Reliable payment status updates via CHIP webhooks

Subscriptions are card-only. CHIP's recurring tokens can only be issued for card payments, so a form feed set to the Subscription transaction type offers cards only. FPX, DuitNow QR and e-wallets remain available on one-time forms.
