Hello,

I have a web catalogue administration system (in Classic ASP) that manages products. When a product is created or updated, I want the website to sent a JSON request to Zoho CRM:

1. If the product already exists (using a key as the test) then Zoho will send back a JSON response, which will trigger the website to send the product updates in JSON to Zoho. Zoho then allows relevant fields to be updated with new data,

2. If the product does not exist, then Zoho will send back a negative response, which will trigger the website ti send the product information as a "new product request".

I do not want the users to have to log in each time, as some of the users are not registered users in our Zoho acount. I do not want to have to automatically (hourly) send a request for an refresh token, as Classic ASP does not allow that functionality. 

I would like a simple way to get an access key to provide the authorisation. This can be encrypted on our web server and will be respected by Zoho CRM as valid authorisation.

Please can you tell me how to set this up as it does not seem to be possible.

thanks

Ben
