understanding Zoho Support API limits

understanding Zoho Support API limits

We are using Professional Edition and have 25 active licenses.  We have written some code that inserts requests into Zoho Support using the XML API   https://www.zoho.com/support/help/add-records.html. Th e code works fine. It uses a single authtoken, generated by the admin user.

We reviewed the API limits on this page  https://www.zoho.com/support/help/api-guide.html#API_Limit ; it says that Professional Edition has a limit of
Minimum - 250 Requests / day / User licence, Maximum - 5000 Requests / day / Organization  

Our code will only be using a single user's authtoken - i.e. we will not be using several users' authtokens. So do we only get 250 daily requests? Or do I get 250 * 25... with a maximum of 5000 daily requests? We are unsure which of the two rules applies here, because we are using a single user license's authtoken to make all API requests.

I hope the question is clear. Thanks for your help. best regards
