US agencies often inherit client NMI credentials from an ISO or payment partner. Gravity Forms is already approved for lead-gen and order intake. The gap is a maintained payment add-on—not a one-off snippet from a forum thread that stops working after a PHP upgrade.
PatSaTECH has integrated NMI-family gateways since the early WooCommerce era. This guide explains why buyers choose our NMI for Gravity Forms product. Neutral checklist: choosing a Gravity Forms payment add-on.
1. Confirm your NMI integration type
NMI supports multiple connection models (hosted, direct, tokenization). Before purchase:
- Verify API username/password or security keys your ISO issued.
- Confirm MCC, AVS/CVV rules, and 3-D Secure if applicable—background in 3D Secure and SCA.
- Ask whether webhooks or query APIs finalize async payments.
Mismatch between contract and plugin is the #1 waste of budget—use how to evaluate payment gateway plugins.
2. Form commerce use cases
| Buyer | Typical GF + NMI flow |
|---|---|
| Nonprofits | Donation + tribute fields |
| B2B services | Deposit on proposal acceptance |
| Associations | Application fee |
| Franchise intake | Multi-location conditional pricing |
Recurring memberships need token vault confirmation—read Gravity Forms recurring payments and gateways before marketing autopay.
3. PCI and integration style
Many NMI deployments use hosted payment fields or tokenization to limit raw card exposure on WordPress. Compare models in hosted vs integrated payment gateways and PCI scope in plain English.
Async completion still depends on webhooks or server callbacks—payment gateway webhooks — beginner’s guide.
4. Why buy from PatSaTECH
- Catalog clarity: Gravity Forms payment gateways lists processor-specific SKUs—not vague “USA gateway” bundles.
- Renewals protect against NMI field deprecations—see buying a payment gateway plugin.
- Plugin installation support when ISO timelines are fixed.
Exotic split funding or ERP-owned totals → custom payment gateway integration.
5. ISO and agency buyers: standardize across clients
If you resell NMI through an ISO, standardizing on PatSaTECH’s NMI for Gravity Forms reduces per-client custom code. Deliverables become repeatable: sandbox matrix, webhook map, GF feed export, renewal calendar.
Compare against building from scratch using payment gateway plugin vs custom integration—forms are simpler than marketplaces but still deserve maintained integrations.
6. Red flags that should pause purchase
- Plugin page never mentions NMI by name or shows wrong logo/branding.
- No documentation for test credentials layout your ISO uses.
- Reviews citing token failures after NMI maintenance windows.
- Vendor will not clarify webhook vs redirect-only completion.
When in doubt, email PatSaTECH with your ISO integration guide before checkout—or use get a quote for multi-MID deployments.
7. After purchase: operational habits
- Store API keys in a secrets manager—not theme
functions.php. - Train finance where refunds start (NMI virtual terminal vs WordPress).
- Renew license before Gravity Forms major upgrades.
- Log transaction IDs on support tickets only—PCI-safe logging.

| GF feed compatibility | Tested releases | Fragile on GF upgrades |
| Support boundary | Documented | Undefined |
