#!/bin/bash
 
tail -n0 -F "$1" | while read LINE; do
  (echo "$LINE" | grep -e "$3") && curl -X POST --silent --data-urlencode \
    "payload={\"text\": \"$(echo $LINE | sed "s/\"/'/g")\"}" "$2";
done

Usage

echo "$LINE" instead of echo $LINE will prevent * characters to output the list of files in the cwd
