Zoho Mail Forwarding via API not working

Hello Zoho,

I'm trying to setup email forwarding for my users through the API (with organisation authorization)

This is my function:

    def add_mail_forwarding(self, accountId, forwardedAddress, zuid):
        body = {
            "zuid": zuid,
            "mode": "addMailForward",
            "mailForward": [{"mailForwardTo": forwardedAddress}],
        }
        print(body)
        return self.session.post(
            f"http://mail.zoho.eu/api/organization/{self.organizationId}/accounts/{accountId}",
            json=body,
            headers=self.headers,
        )

Also, in the documentation it says that a PUT request is required, however it gives me an error with a PUT request and only seems to work with a POST request.

And I seem to need to swap the accountId and the zuid for it to 'work'

I get a status code of 200 which means success, but I don't see the email forwarding being setup in the admin panel.

Can anyone help me out here?
