# API Reference
source: https://developer.mastercard.com/ethoca-alerts-for-merchants/documentation/api-reference/index.md

The Ethoca Alerts for Merchants API consists of these two services:

* [Alerts Outcome API](https://developer.mastercard.com/ethoca-alerts-for-merchants/documentation/api-reference/outcome-api-ref/index.md) lets merchants and merchant partners provide necessary outcome and feedback about a transaction. This information is made available to card issuers so that they know not to raise a chargeback.
* [Alerts Push API](https://developer.mastercard.com/ethoca-alerts-for-merchants/documentation/api-reference/push-api-ref/index.md) is a webhook (outbound API) that lets merchants and merchant partners receive alerts if they're on the Ethoca network.

<br />

You can see the entire flow of the Alerts for Merchants service and how the two APIs work together on \[the Overview page\](/documentation/#how-it-works).
