Transaction API

Regular transactions are started via the Rubean Pay UI but an additional Transaction API is also available.

Format

Our app expects a JSON with the following outer format:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "type": "object",
    "properties": {
        "con": {
            "type": "string",
            "$comment": "Content of the inner payload. Mandatory field."
        },
        "com": {
            "enum": ["zlib", "none"],
            "default": "zlib",
            "$comment": "Compression method for content. Can be left blank."
        },
        "enc": {
            "enum": ["base64", "none"],
            "default": "base64",
            "$comment": "Encoding method for encoding. Can be left blank."
        },
        "typ": {
            "enum": ["tran", "pers"],
            "default": "tran",
            "$comment": "Defines the type of the request. Either a transaction (default) or personalisation request."
        }
    },
    "required": [
        "con"
    ]
}

in the con (content) field the content with the following inner format is expected:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "type": "object",
    "properties": {
        "type": {
            "enum": ["payment", "refund"],
            "default": "payment",
            "$comment": "Type of transaction. Can be left blank."
        },
        "amount": {
            "type": "string",
            "$comment": "Amount of transaction. Mandatory field."
        },
        "currency": {
            "type": "string",
            "default": "EUR",
            "$comment": "Currency of transaction. Can be left blank."
        },
        "reference": {
            "type": "string",
            "$comment": "Reference of transaction. Can be left blank."
        },
        "amountChangeable": {
            "type": "boolean",
            "default": false,
            "$comment": "Defines if transaction amount can be changed in the Rubean Pay app by merchant. Can be left blank."
        }
    },
    "required": [
        "amount"
    ]
}

Optional fields

Please note the majority of the fields in the payload are optional.

A minimal JSON request for a 50€ payment request is done with these values:

{
  "con": "..."
}

{
  "amount": "50.00"
}

QR Code Transactions

We support the starting of transactions via QR codes. You can create and scan a QR code to quickly start a payment in Rubean Pay. A QR code generator for development has been created here: QR-Code-Generator
