BILLmanager has an open API to communicate with third-party services. It allows you to integrate the billing platform with your website.

The API enables to register clients in the billing platform directly from your website. Alternatively, your clients can order services from the website and they will be redirected to BILLmanager for payment. The system can also upload and update the cost of the services from BILLmanager to the website automatically. It improves the level of user-friendliness for clients and increases your website conversion rate.

Use the following API requests to integrate BILLmanager with the website.


Enabling reCATPCHA for BILLmanager integrated with a website may disturb the normal operation of the billing platform and website. To avoid this, add reCAPTCHA with the same keys as in BILLmanager. Read more in Integration with a website with reCAPTCHA.

  • tzoffset — time zone offset off GMT, optional. in BILLmanager it can be set via JavaScirpt:

User time zone offset

function tzoffset() {
        var january_offset = get_date_offset(new Date(2010, 0, 2)),
            june_offset = get_date_offset(new Date(2010, 5, 2)),
            diff = january_offset — june_offset;
        var result = get_date_offset(new Date());
        if (diff < 0 || diff > 0) {
            result = result + ",1";
        } else {
            result = result + ",0";
        return result;

Client registration

Tariff plans

To automatically upload tariffs prices from BILLmanager to the website,  use the pricelist.export function with the following parameters:

  • elid=PROJECT_ID — Provider id in BILLmanager.
  • onlyavailable — Show only tariff plans that are available for order.

    For example, there are two tariff plans in BILLmanager: "VPS for all" and "VPS for partner". VPS for all is available to all customers of the service provider. "VPS for partner" is available only to the customers from the group"Partners". The API-request without authorization in BILLmanager and with the parameter onlyavailable="yes" will not show the tariff "VPS for partner". The API-request without authorization and with the parameter onlyavailable="off" will show the tariff "VPS for all" and "VPS for Partner". 

  • pricelist — Tariffs plan ids separated by commas. They are to be specified only if you need to get data from a certain tariff plan.

This function returns the cost of tariffs and add-ons in the selected format.

Tariff plans information


How to retrieve information about all tariff plans

To retrieve information about all tariff plans including disabled ones, use the function pricelist.export with the parameter pricelist. 


To perform this operation you must log in to BILLmanager with administrator permissions. 

  1. Receive the ID of all tariff plans. Eg., you can use the function pricelist:
  2. Use the function pricelist.export with the parameter pricelist:
    DIFF — the domain or public IP address of the server with BILLmanager. 

    id_list — all ID of tariff plans created in BILLmanager, separated by commas. 

Service order

Usually, a client chooses the service and its configuration directly on the provider's website. Clicking on Order or Pay for the service buttons on the website will redirect him to the billing platform to complete the order. If the client is not authorized in the system, BILLmanager will suggest registering or logging in under the existing account. After log in/sign up the client will be automatically redirected to the billing platform order page. 

You can redirect clients to different ordering pages:

  • tariff plan page, payment period, tariff plan parameters and payment processing page;
  • tariff plan page with a specific payment period. The client has to select tariff parameters and then make a payment;
  • tariff plan page with a specific payment period and selected parameters. The client only has to make a payment. 

The link to the page where your client can select a tariff plan:

Redirect to tariff plan order page


Request parameters:

  • startpage — page/list that will open after registration/login
  • startform — service order form that will open after registration/login
  • pricelist — tariff plan id
  • project — provider id


The URL standard adds some limits to the symbols you can use. In this regard, you need to encode all links to the URL format; otherwise, the links might be displayed incorrectly.

In the section "Service order" only coded links are used. We can only recommend to use them in such a format.

The example of a link to the shared hosting tariff plan (startform=vhost.order):

Redirect to shared hosting specific tariff plan order page


Link to the order page with specific tariff plan and selected payment period 

BILLmanager automatically generates tariff plan order links. You can find them if the section Tariff plans Edit →section URLs

You can also pass add-ons addon_N=xxx, where N is add-on id, xxx is resource value:

  • integer add-ons — integer value of the resource that a client orders
  • add-on specified by enumeration — id of the enumeration element
  • "client can choose" add-on — id of the add-on added to the main addon. The value of the resource that a client orders shall be passed in the parameter addon_N

You can find the add-on id in Tariff plans Options "Id" field.

Tariff plan order page with selected parameters:

Redirect to shared hosting order page with specific parameters


The example of shared hosting (startform=vhost.order.param) with id 2 (pricelist=2). Set add-on value "Web domain limit" to 15 (addon_5=15) and add-on value "Disk space" to 2048 (addon_3=2048).

Redirect to shared hosting order page with specific parameters


If you need to redirect your client directly to the cart or to the payment page, you need to edit the following parameters: the starform parameter value shall be changed to quickforder, parameter redirect parameter with cart (redirect to cart) value or payment (redirect to service payment) is added.

You can redirect your client to the cart by using this link:

Redirect to the cart


Alternatively, you can redirect a client to the page where he/she can select a payment method:

Redirect to payment method page


Domain order link requires parameters in the 'redirect' parameter:

  • checked_domain — a list of the checked domains with additional parameters. The format:
    • The '-' symbols in a domain name are changed into '_', '.', is changed into '____________'
    • A domain status separated with ':' will be added to the resulting value:
      • 0 — not checked,
      • 1 — available,
      • 2 — in use,
      • 3 — error defining status,
      • 4 — domain is registered in BILLmanager.
    • For domain registration use value — 1 as its status, 2 — for transfer.
    • A tariff id separated with ':' will be added to the resulting value.
    • Domain name selection identifier (0 — not selected, 1 — selected) separated with ':' will be added to the resulting value.

      Example of 'checked_domain' parameter

  • — redirect a client to BILLmanager to fill out the information 
  • domain_action — 'register' for registration of a new domain name, 'transfer'  for domain transfer
  • domain_name — registered domain name
  • selected_domain — domain name encoded as described above
  • selected_pricelist — id of the selected tariff plan
  • PRICELIST_ID — tariff plan id

When passing several values to 'checked_domain', 'selected_domain' and 'selected_pricelist', values are separated with ','.

Example of the link using "redirect" parameter:

Calculating order price

Function pricelist.calculate allows to show the price for a certain service and certain add-ons:

Calculation order price


Client user data specified via su or authinfo may be required to call the function.

To add the cost of the add-on to the total amount of the order, you need to add the addon parameter to the query:

addon_XXX=VALUE — additional resources where: 

    • XXX — Id of the tariff add-on, ADDON_ID.
    • VALUE — the amount of the allocated resource.
