Liquid Web’s Account Management System has a robust API that allows for accessing your account from outside of the Manage interface, such as with the Storm WHMCS plugin. In order to access the API, an API user must be created for that account first. Creating an API user is an easy and straightforward process.
The first step is to login to your Manage account. From there, click on the the “Account” option along the left hand side.
Once in the Account section, click on the User Tab along the top. This will bring you to the users page, which allows you to create an API user by click on the “Create API User” button.
Clicking that button will bring up the creation form, where it will allow you to create the account. Manage will not allow you to use a username that is already in use, and will give a warning if you enter in a username that is already created. It is also recommended that you give the new API user a unique password. Once you have entered the information, click the “Save User” button.
This will bring up a confirmation dialogue, asking if you are sure you want to create this API user. As mentioned in the dialogue, an API user cannot be deleted, only deactivated. Accepting the dialogue creates the account. Once created, you can now login to the API via that user.
