+
+# Accept Direct Payments with Pay & Engine
+
+Learn how to accept fiat and crypto from your customers with Pay and trigger Engine actions, like minting NFTs or transferring tokens to user wallets.
+
+### Requirements
+
+- [A thirdweb Client ID](https://thirdweb.com/dashboard/settings/api-keys)
+- [An Engine Instance](https://thirdweb.com/dashboard/engine)
+
+### Purchase Flow Overview
+
+Before jumping in, it's important to understand the full system, from initial purchase to the eventual transfer of assets. This is a four step process (with an optional fifth):
+
+<DocImage src={DirectPaymentsFlow} />
+
+1. **User Initiates Purchase:** User sends specified funds (ETH, MATIC, USD, etc.) to your backend wallet via thirdweb Pay. Use the `purchaseData` field to pass any item data needed in the webhook.
+   E.g., `{ nftId: 1 }`.
+2. **Pay Processes Purchase:** thirdweb Pay processes the transaction and sends a [Purchase Complete webhook](/connect/pay/webhooks#purchase-complete) to your dapp’s server when the transaction is complete.
+3. **Your Server Calls Engine:** Your server processes the webhook and sends a contract call to the thirdweb Engine backend wallet to perform the item purchase.
+4. **Engine Executes the Transaction:** Engine backend wallet executes the transaction needed to deliver the token(s) to the user’s address.
+5. **(Optional) User Is Notified :** Your server confirms the completed Engine transaction and notifies the user.
+
+Now, let's get started.
+
+<Steps>
+	<Step title="Set Up Thirdweb Engine">
+
+    	1. If you haven't already, [deploy an Engine
+    	instance](https://thirdweb.com/dashboard/engine)
+
+    	2. Create or import a backend wallet for Engine in [your Engine dashboard](https://thirdweb.com/dashboard/engine).
+
+    	3. Send the required funds to the backend wallet
+    		* For example, if purchasing with Arb Nova USDC, then your backend wallet should hold this ERC20 token.
+    		* If your backend wallet holds an ERC20 token, ensure to add a native token balance as well to cover gas costs. For example, for a transaction on Arbitrum Nova, your backend wallet should hold both Arb Nova USDC (for payment) and Arb Nova ETH (for gas).
+    		* Your backend wallet should hold enough liquidity to handle any anticipated purchasing volume.
+
+    	4. Make a plan to monitor and keep the float wallet topped up to avoid any issues with the service.
+    </Step>
+    <Step title="Integrate thirdweb Pay (Client)">
+    	1. [Integrate thirdweb Pay](https://portal.thirdweb.com/connect/pay/build-a-custom-experience) on the client side to enable fiat and crypto payments.
+
+
+    	2. Specify the required parameters for your Pay transaction.
+
+    		```ts
+    		const quote = await getBuyWithFiatQuote({
+    			client: client, // thirdweb client
+    			fromCurrencySymbol: "USD", // fiat currency symbol
+    			toChainId: arbnova.id, // arbitrum nova chain id
+    			toAmount: "100", // amount of token to buy
+    			toTokenAddress: USDC_TOKEN_ADDRESS, // address of payment token
+    			fromAddress: "<USERS_WALLET_ADDRESS>",
+    			toAddress: "<YOUR_WALLET_ADDRESS>",
+    				purchaseData: {
+    					nftId: 1
+    				}
+    			});
+    		```
+
+    		|Parameter|Type|Description|
+    		|----|--|--|
+    		|fromCurrencySymbol|`string`|The fiat currency symbol you'd like to accept (currently limited to USD and EUR) |
+    		|toChainId|`string`|[Chain ID](https://thirdweb.com/chainlist) for the destination token.|
+    		|toTokenAddress|`string`|Address of the destination token.|
+    		|toAmount|`string`|The price of the asset denominated in your desination token.|
+    		|fromAddress|`string`|The user's wallet address.|
+    		|toAddress|`string`|The wallet you'd like funds to be sent to. This can be your business wallet or an Engine backend wallet. |
+    		|purchaseData|`Object`|Any details you need to pass in order to track your transaction. If this is a secondary sale, you may want to include details like `{ nftId: 1, orderId: 1 }` |
+
+</Step>
+  <Step title="Integrate thirdweb Pay (Server)">
+		1. Create a “Purchase Complete” webhook in [the Pay dashboard](https://thirdweb.com/dashboard/connect/pay).
+		2. The [Pay webhook POST response](/connect/pay/webhooks#purchase-complete) will include the BuyWithCryptoStatus or BuyWithFiatStatus in the body.
+			* This will also include the purchaseData you previously passed (metadata identifying the customer information, etc.).
+			* A request will be sent on every status change.
+		3. Listen for [completed purchase statuses](https://portal.thirdweb.com/connect/pay/build-a-custom-experience#Poll%20for%20Transaction%20Status).
+			* Note, if this is a two-step BuyWithFiat transaction (onramp, then swap), you should also listen for `CRYPTO_SWAP_COMPLETED`
+		4. When a purchase is completed, determine the purchaser, order and validate the amounts.
+			- The fromAddress in the status will show purchasing address
+			- The purchaseData will contain more information you previously for the purchase details
+			- Validate the information. For example, 100 USDC was sent to your wallet.
+		5. Send a contract call to Engine for the float wallet to purchase the item
+			- For example, send a transaction to the float wallet for `mintTo(fromAddress)`
+			- For secondary purchases, like a marketplace direct listing, you can use the appropriate Engine endpoint, passing the ultimate recipient of the NFT as the buyer
+		6. Confirm the purchase was successful.
+  </Step>
+</Steps>
+
+Once you've completed all of these steps, you'll be ready to offer a great purchase UX for your users.

+
+# Webhooks
+
+Pay can be configured to send webhook events to notify your application any time an event happens on your transaction. Pay sends a response, via a HTTP request, to any endpoint URLs that you have provided us in [the Pay dashboard](https://thirdweb.com/dashboard/connect/pay).
+
+## Events
+
+To listen to events, create a webhook in [the Pay dashboard](https://thirdweb.com/dashboard/connect/pay). Webhook URLs must start with `https://`.
+
+| Event               | Description                         |
+| ------------------- | ----------------------------------- |
+| `purchase_complete` | A transaction is confirmed onchain. |
+
+### Purchase Complete
+
+Triggered when a transaction is confirmed onchain. This event provides information about the new status of the order and its transactionHash, as well as other relevant information.
