# V2

## General information

Api endpoint for all requests is:

```
https://app.wllxpay.io/api/v2
```

#### Deposit flow

1. You obtain new address from WllxPay API (for some currencies it may be address and tag) and store it somewhere on your side. After that you show this address to your customer in order to make a deposit.
2. Customer sends some funds to this address.  
3. When transaction is sent by a customer - WllxPay sends a callback to your callback url with transaction details. It contains status, address, currency, amount and fees. \
   If status is successful, you should deposit respective amount to customer balance on your side.

#### Withdrawal flow

1. You request to send amount of money to address.
2. Your request is validated on our side. If signature is correct, address is valid and you have enough balance - WllxPay responds you with the transaction object.
3. You will receive a callback when transaction status is updated.

**Deposit with exchange flow**

You don't want to touch or store cryptocurrency, but only use it as a payment method. Your customer deposits **BTC**, WllxPay instantly converts it to **EUR** so that **you would receive EUR on your WllxPay account.**

1. You obtain new address from WllxPay API same as in deposit flow, but additionally pass another parameter "convert\_to" in your request specifying resulting currency.
2. When new deposit is arriving, WllxPay converts all arriving funds to destination funds, and sends notifications as in regular deposit

**Withdrawal with exchange flow**

You wish to send Cryptocurrency from your Fiat currency balance. For example you want to **send EUR amount** but your customer receives money **in BTC.**

1. You do exactly same as in withdrawals, but you specify 2 currencies. One is a currency of your **sending balance** and Second is a **cryptocurrency your Customer wishes to receive**.
2. Your request is validated on our side. If signature is correct, address is valid and you have enough balance - WllxPay responds you with the transaction object.
3. You will receive a callback when transaction status is updated.

Business logic for using cryptocurrency as a deposit method: \
You are willing to let your customer fund his EUR balance on your platform or website. You will have to generate an address in the desired cryptocurrency and specify EUR as a "convert\_to" currency. This will allow you to let your Customer pay if his favorite currency and fund his balance in EUR. At the same time you will see respective EUR amount in your WllxPay merchant account.\
**Hint:** you don't have to generate new address for this customer anymore, address can be reused unlimited amount of times.
