Gravity Forms turns forms into revenue: donations, deposits, event registrations, and B2B orders. The payment add-on you choose must match your processor contract, currencies, settlement countries, and whether you need subscriptions or one-time charges.
Unlike a simple WooCommerce product checkout, forms often have conditional fields, multi-page flows, and custom totals—so “it works in the demo” is not enough. This checklist helps you evaluate add-ons the same way we evaluate integrations at PatSaTECH: processor fit first, then UX, then long-term maintenance.
Browse verified extensions in Gravity Forms payment gateways. For Woo-centric stores, see WooCommerce payment gateway plugins.
1. Confirm your processor contract first
Before you purchase software, confirm with your acquirer or processor:
- API product you are approved for (hosted page vs direct API, etc.).
- Countries and currencies you may present and settle.
- MCC, 3-D Secure, and any industry restrictions.
No WordPress plugin can bypass processor limitations. If documentation is vague, implementation risk is high—similar to the framework in how to evaluate payment gateway plugins.
2. Hosted vs direct (and PCI scope)
Hosted flows collect card data on the processor’s infrastructure (redirect or embedded hosted fields), which often reduces merchant PCI scope when implemented correctly. Direct integrations may offer tighter UX control but increase compliance and testing responsibility.
Ask each add-on vendor: where does card data touch your origin, and what SAQ path do similar merchants use? Confirm with your acquirer—not marketing copy alone. Background: hosted vs integrated payment gateways and PCI basics for WooCommerce merchants.
3. Recurring payments and schedules
If you need installments, subscriptions, or saved cards, confirm:
- The add-on uses your gateway’s tokenization and billing agreement APIs correctly.
- Failed payment and retry behavior matches how you communicate with customers.
Not every Gravity Forms payment plugin supports recurring equally. For subscription-heavy stacks on WooCommerce, compare subscriptions and payment gateways.
4. Refunds and finance workflows
Clarify where refunds are initiated:
- Entirely inside WordPress
- Only in the gateway portal
- Both, with sync rules your bookkeeper understands
Mismatch between WooCommerce-only merchants and form-based merchants is a common source of reconciliation bugs—see chargebacks vs refunds for dispute vs merchant-initiated reversals.
5. Webhooks and async completion
Forms often complete before the customer returns from a redirect. Ensure webhooks or IPNs mark entries paid even if the browser closes—patterns overlap with webhook monitoring for WooCommerce (same discipline, confirm GF-specific hooks for your stack).
6. Developer fit: fields, partial payments, edge cases
Test on staging:
- Conditional pricing and multi-page forms
- Partial payments or deposits if you use them
- Spam protection that does not block legitimate corporate buyers
If your workflow is unusual—split payouts, ERP as source of truth, headless posting—custom payment gateway integration may outperform brittle snippets.
Decision summary
| Question | Why it matters |
|---|---|
| Is my processor + product explicitly supported? | Avoid abandoned APIs |
| Hosted or direct—documented clearly? | PCI and QA scope |
| Recurring supported end-to-end? | Token + retry semantics |
| Refunds where finance expects? | Fewer month-end surprises |
| Webhooks for async success? | Fewer “paid but pending” tickets |
Mistakes to avoid
Common pitfalls align with 7 mistakes when integrating a payment gateway: wrong environment keys, ignored callbacks, and caching breaking payment return URLs.
