Webhooks problems with &

Webhooks problems with &

   I have a serious problem in my application. 
    I'm using webhook to save some information in an external database. 
    However, some companies use "&" in its name. By the time I call webhook by step information via POST, the "&", which is placed in the middle of the call, spoils the whole process. 
    What up. You have encountered one of these fails? Have a workaround? 
    If you can answer, I'd be grateful.
