Payments via PayMongo for WooCommerce


Accept Visa, MasterCard, GCash, GrabPay and PayMaya directly on your store with the PayMongo Payment Gateway for WooCommerce


If you are coming from a plugin version lower than 1.6.x, please follow this guide.

* Paymongo API only supports the PHP (Philippine Peso) currency at the moment. Prices for your shop should be configured to PHP for the plugin to work.
* Paymongo API can only process at least P100.00 for the total amount to be paid.
* Some WordPress themes/plugins may not be compatible with this plugin. To isolate which theme/plugin, you may follow this guide. Once isolated, you may contact CynderTech here to address your concerns.


This plugin was developed by CynderTech Corp. in collaboration with PayMongo Philippines, Inc..

Simple and easy payments on your store

The PayMongo plugin extends WooCommerce enabling you to take payments using PayMongo’s Payment API.


  • PayMongo Gateways on WooCommerce Payment settings
  • The settings panel used to configure the gateway.
  • Normal checkout with PayMongo.
  • Checking out with GCash.
  • Checking out with GrabPay.


This gateway requires WooCommerce 3.9.3 and above.

Automatic installation

  1. Log in to your WordPress dashboard.
  2. Navigate to the Plugins page from the left sidebar.
  3. Click the Add New button on the upper left corner of the main panel.
  4. In the search box on the upper right corner of the main panel, type PayMongo Payment Gateway for WooCommerce and wait for it to load.
  5. Once you found the PayMongo Payment Gateway for WooCommerce plugin item, click Install Now.

Manual installation

The manual installation method involves downloading our plugin and uploading it to your web server via your favorite FTP application. The WordPress codex contains instructions on how to do this here.

Setup and Configuration

This step assumes you have already installed the plugin on your WordPress deployment, alongside the WooCommerce plugin

  1. Activate the plugin.
  2. From the left sidebar, navigate to WooCommerce > Settings > Payments.
  3. Look for the Card Payments via PayMongo option and click the Set Up button.
    • Note: The main API key settings of the whole plugin is inside the card payment option subsection. You need to configure the plugin in this section even though you’re not gonna accept credit/debit card payments through PayMongo.

Test Configuration (Optional but highly recommended)

Before accepting actual payments for transactions, it is ideal to test payment workflows using the test mode. Below are the steps to configure your plugin in test mode.

  1. Under the Test Environment subsection, enter your test public key and test secret key in their respective fields. You may obtain your test keys by registering an account at PayMongo.
  2. Click the Save Changes button.
  3. Proceed with testing by ordering items from your store and head to checkout.

Live Configuration

  1. Under the Live Environment subsection, enter your live public key and live secret key in their respective fields. You may obtain your live keys by registering an account at PayMongo and have it verified.
  2. Click the Save Changes button.
  3. Done.

E-wallets Configuration

For e-wallet transactions, you need to specify a webhook secret key in the e-wallet settings. You can generate one using Cynder’s Webhook Secret Key Generator. A convenience link is provided just below the field. After generating a webhook secret key using the key generator, paste it on the webhook secret key field.

  • Note: The webhook secret key field is ONLY REQUIRED if you would be enabling GCash and/or GrabPay as payment method/s for your platform. This allows PayMongo to notify WooCommerce about payment processing using these methods after payment has been authorized by the customer.

  • Note: The key generator requires a specific URL provided to you by the plugin under the webhook secret key field (ex., as well as your test secret key.

  • Note: If you’ve generated a key for the same domain prior to the current update, you can retrieve it using the Retrieve section of the key generator.

  • Note: Setting the webhook secret key for either GCash or GrabPay configures both options. You can just enable or disable each payment option depending on your needs.


Automatic updates should work like a charm; as always though, ensure you backup your site just in case.

What I really like about this is we can get these payment options right off the bat which is really hard in the Philippines. Although they could still use some improvement. Still great though. Keep on improving this!

been waiting for paymongo to be ported in woocommerce. thank you for this. I think you need to redesign the logo for each payment method, credit card, gcash and grabpay. Its quite big. Can you please update it to look more professional the logo?
