Custom variables

In addition to Buckaroo variables, you can add merchant-related variables to each transaction request. These variables can be included in the response and push updates. There are two types of variables:

Custom variables

Configured in advance in the Payment Plaza, custom variables are visible and searchable. The syntax is cust_[variablename] (e.g., cust_event). Custom variables are case-sensitive.

📘

Note

The syntax cust_[variablename] only applies to HTML and NVP gateways, as well as httppost-content-type Push, batch file column names and PPE or Transfer email templates in the Plaza. For an example of a JSON code snippet, check the bottom of this page.

Custom variables in JSON

"CustomParameters": {
   "List": [
   {
       "Name": "name_of_the_plaza_field1",
       "Value": "Example of field value"
   },
   {
       "Name": "name_of_the_plaza_field2",
       "Value": "600"
   }
  ]
}

Additional variables

Not configured in advance, additional variables are found in transaction details but are not searchable. The syntax is add_[variablename] (e.g., add_MyShopNumber).

📘

Note

Both custom and additional variables are optional and it is not mandatory to include these variables. Not entering these variables does not trigger an error message.
