Here is a minimalist example of such a function:

exports = function(payload, response) {
  // retrieve collection name from querystring (e.g. ?coll=myCollection)
    const {coll} = payload.query;

    // log collection name to confirm receipt from querystring
    console.log("collection name passed: ", coll);

    // query a mongodb service, passing the parameterized collection name
    const doc = context.services.get("mongodb-atlas").db("mydb").collection(coll).find().toArray();

    return  doc;
};

Test in Stitch Function Editor: 

exports({query: {coll: 'myCollection'}})

Test outside Stitch (e.g. in Postman)

Use the Webhook URL generated by Stitch, then append the query parameter.
