Calling parametrized REST url from VBCS

Content

Hi

I have the below requirement

1) Landing page has text box, button, table format for output.

2) when I click the button, it will take the text from text box and call below url, and show the results below as table. Attached screen shot for reference.

https://xxxxxxxxxx.oraclecloud.com:443/ic/api/integration/v1/flows/rest/BRM_GET_ACCOUNT_DETAILS/1.0/accounts/{accid}

How to pass the input text to the above url accid? Also need to pass authentication to fetch the values from URL.

It could be great if any javaScipt exist OR suggest any simple solution.
