Payments parameters
In order for a merchant to become a WebMoney.eu Merchant, the merchant will have to register with the WebMoney.eu Merchant service. Moreover, he/she will have to configure the following set of properties to be able to accept payments and notifications about payments.
Properties are configured on the page: "Settings" (Note, that this menu item will be available only if your merchant was approved by issuer).
On the Settings page you can find a listing of all functional merchants and their details; you can edit and delete your merchant account or add a new merchant account.
There is a special set of properties for each Merchant.
Below you will find a listing of all properties and their values:
|
Property Name

Description
|
|
Unique ID
|
an integer (invariable)
|
This is an ID of your merchant account (its number)
|
|
Active Flag
|
Yes/No
|
A flag that allows or prohibits the merchant to receive payments via the service. If this flag is set to Inactive, the WebMoney.eu Mechant will always return an error message to the customer.
|
|
Test Flag
|
Yes/No
|
If this flag is set to Test, the service will send simulated payment details to the merchant system, which will not relate to actual payments made within the Paymer service (according to the PM_PAYTEST_MODE field in the request sent to the service).
|
|
Free amount
|
Yes/No
|
If Free amount is enabled, data on amount and payment type will be taken from a request to the service according to the following rule:
-
If neither amount nor type is defined in a request sent to the service, they will be variable (thus, customers will have to enter the amount and type manually)
-
If the type is specified, only the price (amount) will be variable
If a merchant account does not support the Free amount option, amount and type will be defined as follows:
-
If the type was sent in the request, it will be parsed to check whether it matches allowable merchant types and amounts (if the amount is blank, the customer will have to enter it).
-
If the type was not sent in the request, the first type from the listing of allowable types will be used.

Allow URL Overrides
