Based on the documentation provided at the URL below there is literally no information on what the value requirements are:

If I remove the VerificationToken I am getting a SUB-520 Error
Content: {"errorCode":"SUB-520","message":"Validation Token is not returned","errors":[{"errorCode":"SUB-520","message":"Validation Token is not returned"}]}

@Smit Shah Could you also share the request body along with the question?
The error messages suggest the issue was with the request, looking at the request body would be really helpful
P.S - The API reference is to see the API contract with some basic information.
The developer guide has more details on things like use cases, what fields are used etc.
Information on verification token, validation token and why they are used is mentioned here already

In your original post, it shows the error message of verification token is invalid.
Then in your comment, after removing the verification token, you got a different error "validation token is not returned", this meant that RingCentral server tried to validate your Webhook endpoint by sending a validation token and it expects to receive the token back within 5 secs. But it did not receive it.
See this [getting started example code][1] for how to handle the return of validation token.
