How to make a post request to this API?

I want to make a post request to this api, can you help me to do it through blocks?

-H "content-type: application/json" \
-d '{
  "amount": 50000,
  "currency": "INR",
  "receipt": "receipt#1",
  "payment_capture": 1

Hi @rachit2672
Before helping you we will like to see your own logic.
First show what you have tried then anyone can help you.

you might want to try something, you can use this as a start App Inventor Tutorials and Examples: Dropbox | Pura Vida Apps

however I don’t know, if this will be possible, probably you can set it in the header, too?
