# Payment with external confirmation

> Initiate the payment in the conversation and confirm outside WhatsApp. Brain Studio continues the flow when it receives the official status from the provider.

The **payment with external confirmation** starts in the conversation, but the confirmation occurs outside WhatsApp.

The user completes the transaction in an external app, and Brain Studio continues the flow only when it receives the **official payment status** from the provider. This experience applies when there is no native in-chat capture or embedded WebView checkout.

## Scope of this experience

* Initiates the payment from a button or link within the conversation.
* The user confirms the transaction in an **external provider app**.
* The provider sends the official payment status.
* Brain Studio continues the flow based on that status.
* Does not capture card data in chat.
* Does not open a WebView inside WhatsApp.

Your flow must explicitly handle the returned statuses (pending → confirmed / rejected).

***

## Prerequisites

To implement external confirmation you need:

* Install a compatible provider from **Marketplace** (**BYOK** model).
* Configure valid provider credentials.
* Model status handling within your flow or agent.
