First I'll need an access token which requires an authorization request and the options are the web-based application and self-client according to documentation here: https://www.zoho.com/crm/developer/docs/api/v3/auth-request.html. Because access tokens expire after 1 hour, they need to be generated every time a user interacts with the web form.

Both of these options seem to necessarily require that our visitors have an account within our CRM in order to get a grant token. Is it possible that an access token can be created without a OAuth server redirect instead for this use case?
