Follow the steps below to create and configure the Products Reseller product:

1. In order to create a new Products Reseller product, go to 'System Settings' → 'Products/Services'.
Press 'Create New Group' to add a new one.

Note that there is no server that shall be selected. Your product is ready to order!

• Create - once a client orders the product, go to Client's Products/Services and run the 'Create' action.
  When successful, the client appears on the list of resellers in your addon (see the screen below)

• Suspend - after successful Suspend action in the Client's Products/Services, the ' API Key Status ' of this reseller is switched off

• Unsuspend - run 'Unsuspend ' command to again switch on the reseller's 'API Key Status '

• Terminate - when the product is terminated, the Reseller's 'API Key Status' is again switched off

They will get access to 'Reseller Area', where from they can resell the products, that belong to the pricing group, further.

In a basic workflow 3 users take part:
Provider – a person with Products Reseller For WHMCS installed on the WHMCS system.
Reseller - a provider's client who aims at reselling products offered to him by the provider.
The reseller must own a system with integration module generated for him by the provider with Products Reseller For WHMCS.
End Client – a person with a client account in the Reseller's WHMCS.

Provider's Part
Let us start from the beginning. Provider installs Products Reseller For WHMCS in the system.
He already has some products in the offer and wishes to allow the reseller to resell them.
Now, the provider configures Products Reseller For WHMCS, creates groups, configures them and assigns products, config options and defines their pricing for the reseller who is assigned to one of the groups.
Finally, selects which of the clients will become resellers, assigns them to previously created groups and generates access details.

Reseller Part
The Reseller has access to the Reseller Area once logged into the provider's client area.
There, he can download both the integration module and its documentation as well as generate and copy any API details required to activate the integration module in his own system.
Then, the reseller needs to set up products that the provider allows him to resell with the integration module delivered by the provider. Defines the pricing (prices must be higher than the ones the provider has set up to generate any income).
There is one step that separates the reseller from offering the product from his system.
The reseller must add funds to his credit balance in the provider system to be able to pay off the charges and settle the amounts owed to the provider for his resold products.
Provider creates an 'add funds invoice' for the Reseller, the Reseller pays the invoice and then again the Provider adds the same amount to Reseller's credit balance.
From now on, any product can be ordered.

End Client
End Client orders a product from his client area in the Reseller's system.
Once the payment is complete, details of the ordered product (i.e account credentials) are sent to the end-client mail address using the selected reseller's welcome email template.

Last Word About Payment
Now, that the End-Client has ordered and paid the reseller for the product, at the provider's system a new invoice for that product is created automatically (on behalf of the reseller).
Depending on the selected "Payment Type" configuration the invoice will be paid with credits and product attempted to be created or attempt to create the product and if successful, the invoice will be paid with credits.
In case the reseller does not have sufficient credits on his account to pay for the product creation, the process is stopped until the invoice is manually paid by the reseller.
The reseller's income is the difference between the price of the sold product to the End-Client and the price he paid to the provider.

• Product A (without any config options) → Product B (without any config options) - additional payment is required or adequate amount of money is returned, depending on the number of days remaining until the end of the billing cycle
• Product A (with config options) → Product B (without any config options) - additional payment is required or adequate amount of money is returned, depending on the number of days remaining until the end of the billing cycle
• Product A (without any config options) → Product B (with config options):
  • Case 1: products A and B have the same Configurable Options Group assigned - additional payment is required or adequate amount of money is returned, depending on the number of days remaining until the end of the billing cycle
  • Case 2: products A and B have different Configurable Options Groups assigned - this upgrade scenario is not supported
• Changing billing cycle within one product (with or without configurable options) - additional payment is required or adequate amount of money is returned, depending on the number of days remaining until the end of the billing cycle

1. In the provider's WHMCS:

• First, you need to track the Service ID number and the Order ID number, both of which can be found in the provider's WHMCS system.
  Open the service details page by navigating to: WHMCS Admin Area → Clients → Products/Services → [Your Service].
  
  • When you open the service page, look at the URL; it ends with a number, which is the Service ID. You will need this number to import the product into the reseller's store. Copy it and keep it for later use.
  • While on the same page (Product/Service Details), find the Order ID number under "Order #." Copy this as well, as it will be needed in the next steps.

• Next, you need to order the product for your client account without processing the create command.
  Ensure that the order includes only this single product. If you add more, the process might be interrupted.
• In the client's 'Products/Services' management tab within your admin area, fill in the 'Service ID' and 'Order ID' custom fields with the corresponding ID numbers from the previous step.

• This is the final step. In the provider's database, open the 'ProductsReseller_ResellerRelations' table and add an entry with the newly ordered service details. Ensure that you provide the following:
  • 'resellerid': The 'Admin ID' number.
  • 'rellid': The 'Service ID' custom field value.
    

When ready, change the service status to 'Active'.

That's it! The service has been successfully imported and can now be managed by the end user in the reseller's client area.

You are able to easily prepare integration module for any system (Blesta, HostBill, Clientexec, BoxBilling, and many more) using Products Reseller For WHMCS API.
All you need is knowledge of, for example, the PHP programming language and our module's API.

• Navigate to the ~/langs/ directory located within the following yourWHMCS/modules/servers/moduleName/langs/ path.
• Within this directory, create a new file or duplicate the language file you intend to modify. For instance, if you wish to create an override for the English language, establish the following directory structure:

 ~/langs/overrides/english.php.

• Open the newly created override file to edit its contents.
• At the beginning of the file, indicate the used code, for instance, you can use: <?php for PHP code.
• Adapt the file content according to your requirements. You can either selectively modify specific variables or opt to revise the entire content of the language file.

For example:

Original yourWHMCS/modules/servers/moduleName/langs/english.php:

 $_LANG['Search'] = 'Search';

Override yourWHMCS/modules/servers/moduleName/langs/overrides/english.php:

 $_LANG['Search'] = 'Look for';

Remember that some of the modules have more than one language file, located under /addons and /servers paths. You may create the override files for both of them.
Note that you do not need to paste all the original content of the lang file into the override file. Enter there only the lines that you wish to change, every other line will be fetched from the original module lang file.
Consequently, the override lang file might include only one or just a few lines.

Ensure successful completion of the module update by carefully following each step, thereby preventing data loss or any unforeseen issues.
Additionally, you will find a current list of supplementary actions necessary for a smooth update process there.

Opt for the Open Source version of your Products Reseller For WHMCS module to unlock these benefits.
Simply click on either the Get Source Code or Upgrade To Lifetime button found on the product's page in our client area to complete the one-step upgrade process, with a dedicated discount already applied.

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.

• The product that is offered to the reseller has the 'Recurring' pricing set properly.
• The reseller has enough credits on his account to pay for the product.
• The 'Automatic Credit Use' option is enabled in WHMCS → General Settings → Credit.

This can be e.g.:

        location /client/modules/addons/ProductsReseller/api/ {
                try_files $uri $uri /client/modules/addons/ProductsReseller/api/index.php;
        }

but may differ depending on your configuration (e.g. the '/portal/' path may be used instead of the '/client/' one).
