VGSCollectFieldNameMappingPolicy

Map fieldName to JSON without applying any transformations. FieldName is used as single key. Example: card_data.number => JSON

{
 "card_data.number" : "4111-1111-1111-1111"
}

Map fieldName to nested JSON. Example: card_data.number => nested JSON

{
    "card_data" :
        {
            "number" : "4111111111111111"
        }
}

Map field name to nested JSON and array if array index is specified. Example: card_data[1].number => nested JSON with array

{
    "card_data" :
        [
            null,

            { "number" : "4111111111111111" }
        ]
}

Merge arrays content at the same nested level if possible.

        // Collect fields JSON:
        [
         { "cvc" : "555" }
        ]

        // Extra data JSON:
        [
         { "number" : "4111111111111111" }
        ]

        // JSON to submit:
        [
         {
            "cvc" : "555",
            "number" : "4111111111111111"
         }
        ]

Map field name to nested JSON and array if array index is specified. Example: card_data[1].number => nested JSON with array

{
    "card_data" :
        [
            null,

            { "number" : "4111111111111111" }
        ]
}

Completely overwrite extra data array with Collect Array data.

        // Collect fields JSON:
        [
         { "cvc" : "555" }
        ]

        // Extra data JSON:
        [
         { "number" : "4111111111111111" },
         { "id" : "1111" }
        ]

        // JSON to submit:
        [
         {
            "cvc" : "555",
         }
        ]
