I have just created generic class on google cloud and everything is empty and passing below json data to it as below 

    "textModulesData": [
      {
        "id": "row11",
        "header": "Row11",
        "body": "11"
      },
      {
        "id": "row12",
        "header": "Row12",
        "body": "12"
      },
      {
        "id": "row13",
        "header": "Row13",
        "body": "13"
      }
    ]


Data showing in details screen as below screenshot but its useless.

 Why text fields not showing here in below screenshot?

Answer 1

This is likely due to your GenericClass definition not having a classTemplateInfo defined - which is how you tell Google Wallet how to display any other data in your object, including textModulesData.

I'll create a guide and drop it here later.
