Zoho Books says "Please ensure that the "webhook_name" has less than 50 characters."

Zoho Books says "Please ensure that the "webhook_name" has less than 50 characters."

I have a custom module on Zoho Books that creates a customer trip record. It has a customer field to link to their account information. When these entries are created, I want to fetch this customer's information so I can put the selected customer's address into a slack message. Issue is I keep getting a message that says Zoho Books says "Please ensure that the "webhook_name" has less than 50 characters." Doesn't matter what I change, can't seem to shake this message. Wondering where I am going wrong. This automation would be a huge advancement for us. Please help!
