Sample code to connect to own api point with header, json body

[tsuji koichi]

I m on trial for this new tool, pretty new to Blockspring.

What I m trying to test is if we can build own web data connector to retrieve data through our API endpoint.

API is working fine, tested with postman, by putting header (apikey) along with json body.

Is there anyone who can share the sample code (javascript) so that i can build my own WDC?   I saw the quick sample code, but it seems to be public api, so no api key or other key is required to connect.
