I want to POST data from Postman Google Chrome extension.
I want to make 10 requests with different data and it should be at the same time.
Postman doesn't do that but you can run multiple curl requests asynchronously in Bash:
curl url1 & curl url2 & curl url3 & ...
Remember to add an & after each request which means that request should run as an async job.
Postman however can generate curl snippet for your request: https://learning.getpostman.com/docs/postman/sending_api_requests/generate_code_snippets/
