Hi , the json body of my request keeps changing every now and then , I have over 20 to 30 collections which will use that particular request , is there a way i can change the request body from pre request script ? or any other way i can change the request body dynamically ? so that i dont want to go…

@prasu.eng123 Sure thing. As we need to dynamically set the entire request body, we’ll have to save it to a variable that can be used inside the request body editor. The flow goes something like this: Build the body in the form of a JSON object. This happens inside the pre-request script. var bod…

@prasu.eng123 The best way to do this is to break the body down into individual pieces and set their values using variables in pre-request scripts. Assuming that your request body takes the following form: { "foo": "bar" } If you’d like to make the value of the key foo dynamic, you’d update the…

@kunagpal : Thank for your reply , but this is not what i was looking for . I want to build the whole body dynamically, for example . the json body might sometimes take have 3 key value pairs or four key value pair etc { id :“asdas” pwd:“asdas” auth: “ashd” } or { id :“asd” pwd:“asdas” au…

@prasu.eng123 This can be done as follows: // in the pre-request script var body = {}; // this will contain all the necessary keys pm.environment.set('req_body', JSON.stringify(body)); In the request body (notice how the req_body variable is referenced directy in the raw body): {{req_body}}

Thank you @kunagpal . But i am getting the new line paramaters like \n and\r how can i eleiminate them , any idea ?

@prasu.eng123 Where exactly are you getting these values?

@kunagpal i have a sample request from postman , whose response is the same as data u send. Example beloww . as u can see the data field in response contains the data with \n ad \r Request: postman-echo.com/post Pre request: var body = {foo: "1", password: "asas"}; pm.environment.set('req_body'…

@prasu.eng123 This is happening because the request body is being sent as text instead of JSON. You can fix this by clicking on the mode dropdown to the right of the request body and selecting application/json, as can be seen below: [27%20AM]

Hello @kunagpal , Thanks for the snippet, Could you please explain how can we set dynamic AlphaNumeric string value which is incremental(Letters+Number) to a Json object of the request. Ex: “OrderId”: “ThisValue01234”.

Hi. Why wouldn’t this work on the pre-request script? It’s in the SDK documentation. console.log(pm.request); pm.request.body.raw = ‘Your Request’; console.log(pm.request);
