Shopify does not offer a native PayMongo integration, and Philippine merchants who want to accept GCash, GrabPay, Maya, cards and online banking through PayMongo's developer-friendly APIs usually end up stitching together hosted checkout links or manual payment instructions that break the on-store buying flow. ECOSIRE closes that gap with a purpose-built PayMongo gateway, custom-developed for your specific store and theme.

This is build-to-order software, not an instant App Store install. After purchase, our engineers build the integration against your store, wire it into your checkout flow, connect it to your PayMongo merchant account, and hand it over installed and tested. You receive a working integration — not a generic download you have to configure alone.

Under the hood we use Shopify's Admin GraphQL API, app OAuth for secure store access, and registered webhooks so that PayMongo payment events (paid, failed, refunded) reconcile back to the matching Shopify order. We persist gateway references and reconciliation data in order metafields, so every transaction is auditable from the Shopify Admin. Settlement happens in PHP directly to your PayMongo account.

The build covers GCash, GrabPay and Maya wallets, card acceptance, and bank transfer / online banking, plus refund handling routed through PayMongo's refund API and reflected on the Shopify order. We respect Shopify's checkout constraints honestly — payment-method placement depends on whether your store uses standard checkout or Checkout Extensibility, and we scope that with you up front.

Every engagement includes a discovery call, a staging build, UAT sign-off, and post-launch support. You own the result; we keep it working as Shopify and PayMongo evolve.
