How to add a pause between 2 requests in POSTMAN

I have a collection of requests in POSTMAN. I wanted to add a pause between 2 requests but I couldn't find a way to do so from reading their docs. Any idea?

UPDATE I only wanted to put a pause after one request instead of after every request in the collection.

Solution 1:

In case someone is still looking for this - You can add delay after/before 1 of many test in a collection you can use:

setTimeout(function(){}, [number]);

where 'number' is the milliseconds. If it's added at 'Tests' it will be executed after request is send. If it's added at 'pre-request tests' it will be executed before request is send.

Solution 2:

Using javascript's busy wait is a good hack but it makes your CPU hot and the app unresponsive. I figured out this solution using postman-echo.

Assuming you want to add a long delay between Request_A and Request_B.

First, in Request_A's test script set up an env var to mark the start.

environment.delayTimerStart = new Date();

Then, create a GET request in the creation (here called 'Delay 10s'). It makes a GET on https://postman-echo.com/delay/10 (It returns after 10s)

In its test script, add

var curDate = new Date();
if (curDate - environment.delayTimerStart < delay_time_in_sec*1000) {
    postman.setNextRequest('Delay 10s');
} else {
    postman.setNextRequest("Request_B");
}

In this way you can add a delay of any length.

Note: 10 sec is the maxium value that postman-echo accepts. If you just need a short delay, simply GET https://postman-echo.com/delay/[1~10].
