How to Use the Run Script element

​

Key Features

• The Script element enables you to execute JavaScript code, but it does not allow you to create custom visual elements.
• Variables in the script are evaluated, not parsed, so they must be treated as real JavaScript variables.

Note: Use console.log({{My variable}}) instead of console.log("{{My variable}}").

​

setVariable Function

​

Purpose

​

Example

if ({{My variable}} === 'foo') {
  setVariable('My variable', 'bar');
} else {
  setVariable('My variable', 'other');
}

Important:

• The setVariable function is only available in scripts executed on the server.
• It will not work if the Execute on client? option is checked.

​

Server-Side Script Limitations

​

Restricted Functions

• Global functions like console.log, setTimeout, and setInterval are not available.
• Importing external libraries using import or require is not supported.
• Browser APIs like window, document, and localStorage are not accessible.

​

Fetch Behavior

• The response will always be a string, even if the server returns a JSON object.
• You need to manually parse the response using JSON.parse().

​

Examples:

// ❌ This throws an error
const response = await fetch('https://jsonplaceholder.mycode.com/todos/1');
const data = await response.text();

// ✅ Correct usage
const response = await fetch('https://jsonplaceholder.mycode.com/todos/1');
const data = JSON.parse(response);

Note: Avoid using await response.text() or await response.json().

​

Client-Side Script Execution

​

Examples:

​

Reload Page

window.location.reload();

​

Redirect Based on Variable Value

if ({{Category}} === 'qualified') {
  window.location.href = 'https://my-site.com';
}
