# Request task panel view in H5 game
Divepoint Collection Request Parameters：
```json
{
"merchantId":"1",//String Merchant Number: The merchant number assigned to you by the platform
"ts":1699243390,//Number Request timestamp: used to ensure the uniqueness and security of the request
"sign":"xxxxxxxxxxxxxxx", //String Signs the request parameters to verify the legitimacy of the request
}
```
Signature Method: Follow the sequence provided in the documentation (excluding ts and sign), concatenate the corresponding parameter values into a string, append ts and **UMI-API-KEY** (provided by us) at the end, and then generate the signature using MD5.
Signature String
```javascript
const text = `${merchantId}${ts}${KEY}`;
```
Javascript Example：
```javascript
// Signature Example
const KEY = "UMIVERSE UMI-API-KEY";
let str = '';
// Iterate through the parameter object
for (const key in param) {
if (param.hasOwnProperty(key)) {
const value = param[key];
// Concatenate the parameter values into the string
str += `${value}`;
}
}
// Append the timestamp and secret key to the end of the string
str += `${ts}${KEY}`;
// Calculate the MD5 hash value
const sign = md5(str);
```
Here’s a complete example of a signature generation and API request process using JavaScript. This includes the creation of the signature, appending it to the request, and making an API call:：
