External csv file using url

Welcome to the community @blndazeez! Maybe this post discussed previously should help you get some lights on your issue:

REST request to retrieve a value from an external source

I would like to issue a REST query to an external server to retrieve a value. For example, after entering a name, I would like to check in our database if that name has already been stored. I have seen the REST examples, but most deal with sending, not with receiving data. https://support.kobotoolbox.org/en/articles/978826-pull-data-functionality-in-kobotoolbox is similar, but it does not work for dynamic data. Any hint would be welcome.
