From WHMCS Documentation
For account creation to work successfully with DirectAdmin, you must have your packages setup in your DirectAdmin control panel. Here is how to setup hosting products in WHMCS to work with your DirectAdmin server.
- Setup the Hosting Package in WHMCS as normal (Configuration > Products/Services > Add New Product/Service) entering a name, description, pricing and choosing the server type "Directadmin"
- Next, log into your Direct Admin Server. Once logged in, click Manage User Packages as shown in this image.
- You will then see a list of all your available packages. If you already have the package you are setting up in WHMCS setup in DirectAdmin then you can just copy the name from the list. If not, you will need to create it. Once the package is added, remember the package name shown in the Package column as shown below.
- Once you have this name, then go back to your WHMCS Admin Area and on the Module Settings tab of the Product Setup enter this Package Name exactly as it appears on the list in DirectAdmin above.
