x402 Payment Processing Workflow
Create an n8n workflow that processes x402 payments with error handling and notification systems
// Custom Function node for x402 payment
const x402ApiKey = $node["Set API Key"].json["api_key"];
const paymentData = {
amount: $json.amount,
recipient: $json.recipient,
memo: $json.memo || ""
};
try {
const response = await $http.request({
method: 'POST',
url: 'https://api.x402.com/payments',
headers: {
'Authorization': `Bearer ${x402ApiKey}`,
'Content-Type': 'application/json'
},
body: paymentData
});
return {
success: true,
transaction_id: response.data.id,
status: response.data.status,
timestamp: new Date().toISOString()
};
} catch (error) {
return {
success: false,
error: error.message,
timestamp: new Date().toISOString()
};

Choosing Your Facilitator
The X402PaymentTool is generic and works with any facilitator that has a compatible client. Here's how you might initialize different clients based on your specific needs:
For Enterprise (CDP)
import { CDPClient } from 'x402-facilitators';
const client = new CDPClient({ apiKey: "..." });See the CDP Facilitator Guide for details.
For Zero Fees (Mogami)
import { MogamiClient } from 'x402-facilitators';
const client = new MogamiClient({ walletPk: "..." });See the Mogami Facilitator Guide for details.
For Developer Experience (thirdweb)
import { ThirdwebClient } from 'x402-facilitators';
const client = new ThirdwebClient({ secretKey: "..." });See the thirdweb Facilitator Guide for details.
Custom Setup
// Use any facilitator from our hub
