A lot of time there are some problems which we face occasionally but the time when that occasion become too often it becomes frustrating to keep searching those occasional problem here and there on stack overflow or documentation of the libraries. So I'm starting this series of Problems and Solutions to have my those problems all curated at one place. Let's see how it goes. Some of these problems took me to get through a lot of stack overflow answers to find the right one. I wish it saves someone's time.

5. Copy as CURL

When you're frontend developer you often need to integrate APIs. And a lot of time there might be issues which you would've have to communicate to the backend developer who will be needing things like the payload and header you sent with the api to** check** you passed everything correctly.
Instead, what you can do is send the CURL url to your backend developer which he can import in his API test tool like POSTMAN to check it.

These are few for now and I'll keep coming with more soon. Till then fast solving😁.
