Scripting

Astraio includes a built-in scripting engine for automating API workflows.

Script Types

Type	When It Runs
Pre-request	Before sending the request
Post-response	After receiving the response

Writing Scripts

Pre-request Script


// Set dynamic timestamp
variables.set("timestamp", Date.now().toString());
 
// Generate random ID
variables.set("request_id", crypto.randomUUID());
 
// Set authentication header
headers.set("Authorization", `Bearer ${variables.get("token")}`);

Post-response Script


// Extract data from response
const userId = response.body.data.id;
variables.set("user_id", userId);
 
// Log response
console.log(`Status: ${response.status}`);
console.log(`Duration: ${response.duration}ms`);

Available APIs

Variables


// Get a variable
const value = variables.get("name");
 
// Set a variable
variables.set("name", "value");

Headers


// Set request header
headers.set("Content-Type", "application/json");
 
// Get response header
const contentType = response.headers.get("Content-Type");

Console


console.log("Message");
console.error("Error");
console.warn("Warning");

Crypto


// Generate UUID
const id = crypto.randomUUID();
 
// Generate random string
const random = crypto.randomBytes(16).toString("hex");

Debugging

Use console.log() to output values
Check the Console tab in the response panel
Scripts run in a sandboxed environment
