The rq.info object provides metadata about the current script execution context. It contains information about the request being executed, the current iteration (when running collections), and the event type.

​
Properties

​
rq.info.requestId

Type: string The unique identifier of the request being executed. Example: 
console.log("Request ID:", rq.info.requestId);
// Output: Request ID: abc123xyz

​
rq.info.requestName

Type: string The name of the request being executed. Example: 
console.log("Executing request:", rq.info.requestName);
// Output: Executing request: Get User Profile

​
rq.info.eventName

Type: "prerequest" | "postresponse" The type of script event currently executing. Returns "prerequest" for pre-request scripts and "postresponse" for post-response scripts. Example: 
if (rq.info.eventName === "prerequest") {
    console.log("Running pre-request script");
} else {
    console.log("Running post-response script");
}

​
rq.info.iteration

Type: number The current iteration index when running a collection with the Collection Runner. The index is 0-based, meaning the first iteration is 0, the second is 1, and so on. For single request executions (not part of a collection run), this value is 0. Example: 
console.log("Current iteration:", rq.info.iteration);
// Output: Current iteration: 0 (first iteration)
// Output: Current iteration: 2 (third iteration)

​
rq.info.iterationCount

Type: number The total number of iterations configured for the collection run. For single request executions, this value is 1. Example: 
console.log(`Running iteration ${rq.info.iteration + 1} of ${rq.info.iterationCount}`);
// Output: Running iteration 3 of 10

​
Use Cases

​
Track Progress in Collection Runs

// Pre-request script
const progress = ((rq.info.iteration + 1) / rq.info.iterationCount * 100).toFixed(1);
console.log(`Progress: ${progress}% (${rq.info.iteration + 1}/${rq.info.iterationCount})`);

​
Conditional Logic Based on Iteration

// Skip authentication on first iteration
if (rq.info.iteration === 0) {
    console.log("First iteration - setting up authentication");
    rq.environment.set("authToken", "initial-token");
} else {
    console.log("Using existing authentication");
}

​
Different Behavior for First and Last Iterations

// Pre-request script
if (rq.info.iteration === 0) {
    console.log("First iteration - initializing test data");
    rq.collectionVariables.set("testData", []);
}

// Post-response script
if (rq.info.iteration === rq.info.iterationCount - 1) {
    console.log("Last iteration - cleaning up");
    const allData = rq.collectionVariables.get("testData");
    console.log("Collected data from all iterations:", allData);
}

​
Log Request Context

// Post-response script
console.log(`[${rq.info.requestName}] Status: ${rq.response.code} | Iteration: ${rq.info.iteration + 1}/${rq.info.iterationCount}`);

​
Notes

  • The iteration property is 0-based (starts from 0, not 1)
  • For single request executions, iteration is 0 and iterationCount is 1
  • The rq.info object is read-only and cannot be modified
  • All properties are available in both pre-request and post-response scripts
