BURST SMS Integration

Hi,

I am trying to integrate my Burst SMS account to Zoho CRM.

I have managed this by using the following video https://www.google.com/search?rlz=1C5CHFA_enGB717GB717&sxsrf=ALeKk01ZiAy5y3YsvFfyJ12FhzYtpOvqPw%3A1608575597720&ei=bergX6LHK9aQ4-EP9ra4gAk&q=intigrate+burst+sms+with+zoho+crm&oq=intigrate+burst+sms+with+zoho+crm&gs_lcp=CgZwc3ktYWIQAzIICCEQFhAdEB46BAgAEEdQwQ5YuBRgnBdoAHABeACAAbQCiAGcCJIBBzAuMS4yLjGYAQCgAQGqAQdnd3Mtd2l6yAEIwAEB&sclient=psy-ab&ved=0ahUKEwjiseKI29_tAhVWyDgGHXYbDpAQ4dUDCA0&uact=5#kpvalbx=_cergX-LPKvya4-EPsd226A011

However, the video tells me to copy and paste both a:

Incoming webhook URL & DLR Callback URL. However, Zoho has not produced these for me. How do I find them please.

Many thanks,

Edward
