KeyHelp® WHMCS Module

KeyHelp® WHMCS Module

Developed By

Compatible with WHMCS v8.9

KeyHelp® is a well-known free server control panel from Keyweb AG. Via the API interface available in KeyHelp®, our WHMCS module can communicate directly with one or more KeyHelp® servers.

With our KeyHelp® WHMCS module you and your customers facilitate the interaction between your WHMCS system and the KeyHelp® server control panel.

Your customers get comprehensive options to control domains, email accounts, email addresses (aliases), FTP accesses, databases and SSL certificates directly from the WHMCS customer area. And if your customers do want to go to the KeyHelp® Server Control Panel, an SSO login to the account can be done with just one click.

A special highlight is the possibility to use the WHMCS functions "Usage Update" and "Usage Metrics". The module, together with the WHMCS cronjob, retrieves the actual resource usage from the KeyHelp® Server Control Panel, allowing you to individually bill the customer's actual used disk space, traffic, email mailboxes, FTP accounts, etc. This gives you full flexibility.

Using the WHMCS "Configurable Options", you can override disk space and traffic from the hosting package or add them as an add-on. If your customers need more disk space or traffic than is available in the hosting plan, you can simply offer them for purchase via add-on.

Also, hosting plan/product changes, locks, unlocks, deletions and password changes are possible directly from the WHMCS admin area.

The following actions are supported by the module:

- Customer area: creation / modification / deletion of one or more domains to a customer account

- Customer area: create / change / delete e-mail accounts (POP3, IMAP)

- Customer area: creation / modification / deletion of e-mail addresses (aliases)

- Customer area: creation / modification / deletion of MySQL databases

- Customer area: creation / modification / deletion of FTP users

- Customer area: creation / modification / deletion of SSL certificates (incl. Let's Encrypt SSL certificates)

- Customer area + admin area: SSO login by customer / admin possible

- Admin area: show + use information about server load in WHMCS (e.g. to define maximum number of customers per server)

- Ordering process: Overwrite storage space via "Configurable Options

You can either overwrite the disk space completely individually or add more disk space to the existing package (e.g. as an add-on)

- System: WHMCS Create / Suspend / Unsuspend / Terminate / Change Package / Change Client Password functions directly within the client/product

- System: Manual assignment of existing accounts on the KeyHelp® server to a WHMCS client / product

- System: Usage of WHMCS "Usage Update" possible

- System: Usage of WHMCS "Usage Metrics" possible

The module is continuously developed and adapted to new KeyHelp® Control Panel versions and WHMCS versions.

Selbst als zeitlich begrenzter Testkunde wird man hier vom Support rundum versorgt. Die Anfragen werden sorgfältig geprüft und Satz für Satz beantwortet, anstatt mit Standardtexten abgewiesen zu werden, wie es anderswo oft der Fall ist. Daher eine klare Kaufempfehlung! Das Addon bietet alles, was WHMCS zulässt

v1.1.2 Released February 15th, 2024

Latest Version


  • The module now also transfers the language set for the customer in WHMCS to the account on the KeyHelp® server upon creation (if the language is also available on the KeyHelp® server)
  • The module's configuration file allows setting a custom username for the account creation on the KeyHelp® server instead of the username suggested by WHMCS. The configuration file contains examples for the "first letter of the first name and last name of the customer" or "last name of the customer" variants. Email addresses are not possible, as KeyHelp® does not allow this as a username.
