Hello guys, Just need a bit more clarification regarding the DIY CRM integration. We have followed all the steps in the 3CX CRM Integration ( https://www.3cx.com/docs/crm-integration/ ) as follows: 1 - Selected Basic authentication (for API) 2 - REST 3 - Added all required URLs 4 - Generated project skeleton in Visual Studio 2015 Now we need to change the authentication form to use our API information instead of username and password as per instructions on this page https://www.3cx.com/docs/basic-authentication/ . Can someone be kind enough to explain what code to change or provide a sample with dummy API credentials? This would be super helpful! Many thanks to all.
