We have upgraded GCP and introduced another option which will greatly simplify the processing of your orders.
This parameter is called order_id. It allows you to assign an identification number to your order (or to the product) that your client purchased, and then get a wallet address for paying for products by the customer, as you usually do in GCP.
This option allows to:
- quickly identify your order with the wallet address that GCP generates and to which the payment is eventually received;
- easily maintain bookkeeping and internal reporting, where every item id corresponds to its wallet address.
Compare, if before you had to use the merchant_id (see "Flexible statistics in your account") when you wanted to identify items, now you can do it easier and simpler with the order_id, without changing the merchant_id or with using it for more general categories of items.
Therefore, there are 2 parameters in GCP:
- merchant_id which is a high-level identifier;
- order_id which is a low-level identifier.
So, order_id can be used for any item to be paid for, and merchant_id can be used for a category of items within which each has its own order_id. You can make it even simpler: the initial digits of the order_id will already have a category attached to it, e.g. "sporting goods" (in that case the merchant_id is not needed). Do it the way you like.
Also, previously, if you wanted to distinguish between products, you had to request the merchant_id, and only then (specifying the merchant_id) — to request the payment address. Now order_id is specified immediately in the request for payment address. Setup has become easier and more user-friendly!
Cases of using order_id
You may use:
1. order_id only — identifying any order for which a payment is received;
2. order_id + merchant_id — where merchant_id is the name of the product group and order_id is any product in the group;
3. Advanced order_id — which already contains the category to which it belongs as well as other features of the product. For example, the product category is contained in the first 4 characters of the order_id, and the next 4 characters contain other features of the item (colour, size, country of origin, etc.).
Let's take an example of a complex business with:
- many groups and subgroups of products;
- many customers and, consequently, payments;
and preferably using order_id pro (advanced) + merchant_id.
We have several online casinos operating under different brands. Within each of them: different games, modes, users and, consequently, payments. To identify the payments, we can do the following:
Level 1. merchant_id –> business name — Casino X
Level 2. order_id –> game mode — Double game (+ the number of the player, for example, depositing in this game)
Then it would be an advanced order_id, including both game mode and player.
Let's go down a level lower (e.g. if we are inside the same site and there is no need to distinguish transactions from other businesses).
Let's denote the game mode as merchant_id and the player number as order_id. This will be a simple order_id identifying the player only:
Level 1. merchant_id –> game mode — Baccarat
Level 2. order_id –> player number (+ his additional characteristics, e.g. what he bet on)
