Help Needed With POST call request

I trying to make a email verifier , I have the API data . How do I make this happen .

The Payload type is a JSON Data

Once a input form with email id is submitted , the data is sent to the API and is verified by the API and if the email address is valid it will return a success message in the frontend if false then will return an invalid email message , Im quite new to Velo and would love if someone could help me out , thanks in advance .

sendgrid helps to send code

to build a custom register flow

you should get user really registered ONLY after the verification code is correct as expected.

note: copy and paste the example does not work. To learn JS/Velo, see the Getting Started Category of the forum

In case you want to use POST(http):
