custom endpoints with sugar CRM Cloud

hi all,

we have just moved from salesforce to sugar and am now having to integrate all our sites with the data managed in sugar. Have not worked with sugar before so still looking through the api. When we started the company first dealing with the transfer got us a self hosted version of sugar, we quickly outgrow this and have moved to the cloud version of sugar pro.

As we no longer host sugar I wandered where I create custom endpoints for the API as before we just eddited the file ./custom/clients/base/api/MyEndpointsApi.php

ref https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_9.0/Integration/Web_Services/REST_API/Extending_Endpoints/

Does anyone know how we do this with the cloud version as we no longer host the files

thanks
