Hi Valentina.. This is what I was looking for - feed a bunch of input requests from external file. 2 follow up questions: 1) I presume the same concept works for CSV input as well.. Maybe some twaeks to concert CSV to valid JSON; similar to JSON.Stringify you used in this video 2) If I were to run this using Newman CLI and save the responses to a file (another video of yours), how does the file selection part work in CLI (in PM, you select the external file from a folder)?

@BANPHIM00 3 года назад

Thank you so much for your tutorial! I am running into an issue where I have nested JSOn objects and not able to read it into the body, do you have any suggestions?

@sridharmurari3007 2 года назад

Even for nested objects I am unable to read any solution

@osotirov 4 года назад

Hi @Valentin Despa, Thanks a lot, very helpful! Much RESPECT bro!!! In case it's convenient to ask - what about testing part, i.e. how you perform verification of each object from the response?

@vdespa 4 года назад

Thank you for your comment. The testing part is covered in other videos. Let me know if you have a specific question that is not covered.

@osotirov 4 года назад

@Valentin Despa Thanks for your attention. If I have to be honest - you did not answer to my question. I don't ask how to perform verification, i.e testing on the responce in general. My question was specisic to this case you use a file where you have, let say in this way - few bodies at ones, i.e you perform sending of few requests at ones. This is different than general scenario - sending something in the body request and than, verify it in the response request, through pm.test... in 'test' tab at postman. I searched in your videos and found no answer . I found extremely useful and interesting things, but not what I was looking for - how to check exactly this 'multiple request' from your video. I may have missed it, I'm not arguing about that. If this is the case, please give a link in the comment. I will be infinitely grateful to you. I respect and honor a lot what you do, honestly, but I'm not happy with your answer. Sincerely bro - all the best.

@AppFanUAE 2 года назад

thanks for the great help. how It can be executed with predefined file location, so instead of locating it manually I just want it to be executed with specific file, wither its stored locally or from the net?

@vdespa 2 года назад

You're welcome. You can automate this with Newman, but you can't set a predefined location.

@yohannjacob5491 3 года назад

HI i was wondering if we could pass and store the variable internally as a json file instead of taking a file from outside.

@vdespa 3 года назад

Can you shortly explain what exactly you are trying to do? I am not sure I have fully understood. Thanks!

Hi @Valentin Despa ,i have a question. How can i get the json file from my local to the body of the request for individual request?

@vdespa Год назад

Postman can't read files from your filesystem and do that. You need a different approach, which relies on external tools to accomplish this.

@adityakirank 3 года назад

Thx for your tutorials, they are very useful. Is it possible to provide json file with relative path+name as POST body? My json file has just 1 full large payload/object. It is not an array objects, I want to iterate against 1 request?

Hello, I have downloaded latest postman desktop app and followed the steps in this video, but the request body is always null. is steps same in the desktop app also or something has changed recently?

It should work exactly the same. Check again your steps, maybe redo everything from scratch.

@@vdespa Following is the request body of my API call. 👇 { “DomainName”: “string”, “SubDomain”: “string”, “CertificatePassword”: “string”, “Base64File”: “string” } This API call does is, creating a custom domain to a website using wildcard SSL. Instead of Wildcard SSL certificate I have to pass the Base64 file in the request body. But I can't pass the file into the request body. I would be really grateful if you could assit me on this.

@vdespa 2 года назад

@@janithdesilva7518 You can't do this from Postman alone. You need a sever to read the file and make it available over HTTP. You make the request, save the data in a Postman variable and reuse it in this request.

Can we use a data file for indvidual request rather than postman collection?

@vdespa 2 года назад

It is not possible to use multiple files. You need to put all data in a single Json file.

@ganeshmanoharan1316 3 года назад

Can we able to validate the request value is a string or number

@vdespa 3 года назад

You can use the object pm.request. See learning.postman.com/docs/writing-scripts/script-references/postman-sandbox-api-reference/#scripting-with-request-data

If the use the above mentioned Pre-Request only Object is being passed and am getting 400 error. My payload is enclosed within a List how can i read it as List. Kindly could you pls tell me the function to convert to List as well. my payload example: [ { "appcode": "value", . . . } ]
