## Sources

A Source is a resource to generate your customer's payment instrument. This is normally used to generate check out URLs for e-wallet payments. To learn more about e-wallet integrations, you can visit [GCash](https://developers.paymongo.com/docs/accepting-gcash-payments) or [GrabPay](https://developers.paymongo.com/docs/accepting-grabpay-payments) integration.

## Payments

A `Payment` resource is an attempt by your customer to send you money in exchange for your product. This is a reference to an amount that you are expecting to receive if a payment resource with paid status becomes a part of a payout. If the payment status is `failed`, you can determine the reason for failure.

## Webhooks

A `Webhook` resource primarily refers to a certain URL where we send events that are happening from your account. You can check our [GCash](https://developers.paymongo.com/docs/accepting-gcash-payments) and [GrabPay](https://developers.paymongo.com/docs/accepting-grabpay-payments) integrations to find out some good use cases for webhooks.
