We are trying to build an integration with Zoho Books. I am able to make it all work manually, but now trying to wrap it all up to an automated process and I am stuck at being able to retrieve the grant token. To documentation states to redirect to the URL, but our process will have ZERO human intervention. I need to be able to make an automated HTTP request to the URL and extract the "code".

Does anyone know of a way to do this?

Why did Zoho do things so backwards and non-standard with this? Why put the code in the url (unencoded, at that) to where it can only be retrieved by a human? They really should take a few courses on PROPER REST methodology.
