Installation and Authentication

This tutorial will show you how to successfully install and authenticate Google Workspace For WHMCS.

We will guide you step by step through the whole installation and authentication process.

1. Log in to our client area and download the module.
2. In the downloaded file you might find one or two packages that support different PHP versions.

In the most recent versions of the module, you will find only one package that supports PHP 7.2 and later.

Previous updates of the module may contain two packages dedicated to various PHP versions.

The first one that supports PHP 5.6 up to PHP 7.1, and the second one addressed to PHP 7.2 up to PHP 7.4.
Note: Keep in mind that PHP versions 5.6 up to 7.1 are no longer officially supported and their security issues are not fixed or released any more. Find more info here.

Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.

The content of the package to upload should look like this.

4. When you install Google Workspace For WHMCS for the first time, you have to rename the 'license_RENAME.php' file.

The file is located in 'modules/servers/gSuite/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

5. In order to configure your license key you have to edit the previously renamed 'license.php' file.

Configuration and Management

Configuration and management of Google Workspace For WHMCS is very intuitive. Read the below sections to see how easy it is.

Basic Configuration

Let us begin the process of module configuration by choosing Default Product SKU ID. To start with, simply pick one of the available Google services.

A list of the currently supported addons can be found here.

Plan Name allows you to select the method of payment. You can choose between:
  • ANNUAL - the annual commitment plan with monthly payments
  • ANNUAL_YEARLY_PAY - the annual commitment plan with yearly payments
  • FLEXIBLE - monthly billing for the number of user accounts used in a particular month
  • TRIAL - the 30-day free trial plan

Note: Since the 1.1.5 version of Google Workspace For WHMCS module, the ANNUAL plan is equivalent to ANNUAL_MONTHLY_PAY in G Suite API.

Rennewal Type - choose the method of renewing your plan when the current subscription expires. The available options are:
  • AUTO_RENEW_MONTHLY_PAY - at the end of the interval of annual commitment plan, automatically renew the subscription plan with monthly payments and with the same number of user licenses
  • AUTO_RENEW_YEARLY_PAY - at the end of the interval of annual commitment plan, automatically renew the subscription plan with yearly payments and the same number of user licenses
  • CANCEL - at the end of the interval of annual commitment plan, suspend the customer's account
  • RENEW_CURRENT_USERS_MONTHLY_PAY - at the end of the interval of annual commitment plan, renew the subscription plan with monthly payments but use the total number of current active user licenses
  • RENEW_CURRENT_USERS_YEARLY_PAY - at the end of the interval of annual commitment plan, renew the subscription plan with yearly payments but use the total number of current active user licenses
  • SWITCH_TO_PAY_AS_YOU_GO - at the end of the interval of annual commitment plan, change the annual commitment plan to a flexible plan

Action On Terminate - here you can decide whether you want to suspend or cancel customer services upon the termination.
Important!: Please remember that once you choose the 'Cancel' option, the subscription will be deleted immediately. It does not apply to the G Suite subscription.
Create Admin Account & Mailbox Name - select this option to automatically create an administrator account with a given username for the G Suite domain.

Configurable Options

In order to automatically generate configurable options, simply press the button marked on the screen.
In your WHMCS system press 'Setup' 'Products/Services' 'Configurable Options'.

Find the 'GoogleApps' options on the list.

Here you can manage and alter added configurable options.
Provide values for your new option and enter the desired price. Press 'Save Changes'.
In the 'Module Settings' tab of your product you can fill out the fields for ' Default Product SKU ID' and 'Default Number of Seats.
Remember however that these values will be used only if configurable options are NOT generated.
From now on you can easily and quickly change value of your product. Remember that you can add more configurable options for other values.

Admin Area

Let us check your new product on the product page in admin area. It should look like on the screen below.

Client Area

This is how the module will be displayed in the client area. Google Workspace For WHMCS also allows your customers to quickly access Google account services.

Update of Existing Customers

You can link existing customer accounts by filling in the Custom Fields: 'GoogleApps Domain' and 'GoogleApps PurchaseOrderID'.

After your customers order a new subscription, they should insert their primary Google account domain name in the 'GoogleApps Domain' field.
Then, the new subscription will be added to that account.
If you want to manually create an order for an existing subscription, in addition to the above steps, you need to find 'Purchase Order ID' (usually on the invoice).
Copy the ID and paste it to the 'GoogleApps PurchaseOrderID ' field.
Afterward, do not run the create command but just press the 'Save Changes' button. You can also change the status to 'Active'.



1. The module requires a G Suite Reseller account. To check the current status of your Google Reseller account, navigate to the following site: Google Cloud Partner Portal.
There, you can verify the status and request partner authorization if necessary.
2. Avoid using localhost and Raw IP during the authorization.
3. Callback URL is fetched from your WHMCS System URL. You can set it in the 'General Settings' of your system.
4. To change your API access and OAuth, go to the product configuration page and add &logout=1&revoke=1 to the URL.
5. If you want to better understand the concept of G Suite Reseller API and our module, visit this page
6. Some API actions such as 'suspend' may be subject to additional restrictions or have different results depending on the selected plan or the number of days elapsed.
You can learn more about them here.
7. If you want to set different prices for seats depending on the plan, the only way to do that is to create separate products.
More info about setting prices can be found here.

Follow a comprehensive guide covering the transition process, the advantages it brings, and step-by-step instructions on what to do next after the order has been successfully finalized.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. It is possible to receive such an error while authenticating our module:
Error: redirect_uri_mismatch

If such a case, make sure that URLs provided in your Google account and your WHMCS system are the same.
Keep in mind that addresses with the prefix 'www' vary from addresses without this prefix.

3. In case you encounter an error similar to the one below, you most probably disabled the output buffering in the PHP configuration.
Notice: ob_clean(): failed to delete buffer.

To solve the problem, please set the 'output_buffering' value to 'On' in the php.ini file.

4. Due Dates in WHMCS and the Google platform might be out of sync if not set up manually after import, causing the service to appear as active in WHMCS, but suspended on Google's side.

Solution: Try delaying the suspension by a specific number of days after the billing cycle ends, giving clients a grace period.

  • Adjust the 'Suspend Days' value under 'System Settings' → 'Automation Settings' → 'Automatic Module Functions'.
  • Set the 'Renewal Type' of the product to any status other than 'Cancel', as this will cause the account to be suspended as soon as the billing cycle in Google Workspace ends.
