Overall Process

​

Webhook Event

1. Create a Webhook endpoint
   1. Use the n8n Webhook Node to create a new listener
   2. Select POST as the HTTP method
   3. In the Options, set the Response Code to 200 and ensure that ‘Immediately’ is selected

​

Parse the return value and verify the signature

​

Parse the return value

function parseSignatureHeader(signatureHeader) {
  const result = {};
  for (const part of (signatureHeader || '').split(',')) {
    const [key, value] = part.split('=');
    if (key && value) {
      result[key.trim()] = value.trim();
    }
  }
  return result;
}

const input = $input.first().json;
const headers = input.headers || {};
const body = input.body;

const signatureHeader = headers['ycloud-signature'] ;
const parsed = parseSignatureHeader(signatureHeader);

const timestamp = parsed.t;
const receivedSignature = parsed.s;

const payload =
  body === undefined || body === null
    ? ''
    : typeof body === 'string'
      ? body
      : JSON.stringify(body);

const signedPayload = `${timestamp}.${payload}`;

return [
  {
    json: {
      ...input,
      timestamp,
      receivedSignature,
      payload,
      signedPayload,
      signatureHeader,

    }
  }
];

• The original value,
• The timestamp,
• The received signature, the payload, the signed payload, and the signature information in the request header

​

Encrypted data

​

Compare signatures

​

Reply to messages using AI

1. Use the switch node to configure multiple webhook notification types.

2. When an inbound_message_received event is received, a reply can be generated by calling the AI API

3. Use the merge node to retain the collection of webhook push data from the preceding section

4. Sending messages using YCloud nodes

​

Save to a data table (optional)

​

Monitor subsequent updates to the message sent (optional)
