Mangopay Echo is a unified solution for platforms to declare payments not acquired by Mangopay but which then transit the Mangopay environment as part of the workflow. In Echo, the payment authorization is declared as an Intent, and its subsequent lifecycle is declared as actions against the Intent – Intent Capture or else Intent Refund or Intent Dispute. Tracking the externally processed payment in Intents allows the payments to be correctly reconciled against the funds that are received on the platform's escrow wallet. See the integration guide for an [overview of the solution](/guides/echo/integration) **→** ### Flow types Mangopay Echo is applicable to platforms acquiring funds for goods or services sold by your platform directly (first-party or **1P transactions**), as well as for goods or services sold by third-party sellers on your platform (third-party or **3P transactions**).
