# Payment Flow

The following is the workflow for the Aquanow payment service which is a two-step process:

In stage 1, the user initiates a deposit request to the payment company. The payment company will send an requestPaymentAddress POST method request to Aquanow which will return the price, expiry time, quantity and cryptocurrency deposit information.

Stage 2 starts when the user sends cryptocurrency to the deposit address. Once Aquanow has detected the transaction confirmation on the blockchain, Aquanow will convert the deposited cryptocurrency into the destination currency. 

There are two options available for the payment company to detect if the deposit has occurred:

### Option 1: Webhooks Push Approach (Recommended)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.aquanow.io/pay/integration-guide/payment-flow.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
