Motivation and Context

Closes #5396

How did you test it?

To get the metadata use curl:

curl --location 'http://localhost:8080/user/data?keys=ProductionAgreement%2CSetupProcessor%2CConfigureEndpoint%2CSetupComplete%2CFirstProcessorConnected%2CSecondProcessorConnected%2CConfiguredRouting%2CTestPayment%2CIntegrationMethod%2CConfigurationType%2CIntegrationCompleted%2CStripeConnected%2CPaypalConnected%2CSPRoutingConfigured%2CFeedback%2CProdIntent%2CSPTestPayment%2CDownloadWoocom%2CConfigureWoocom%2CSetupWoocomWebhook%2CIsMultipleConfiguration%2CIsChangePasswordRequired' \
--header 'Authorization: Bearer JWT'

In response we will get the metadata both that set or unset:

[
    {
        "ProductionAgreement": false
    },
    {
        "SetupProcessor": null
    },
    {
        "ConfigureEndpoint": false
    },
    {
        "SetupComplete": false
    },
    {
        "FirstProcessorConnected": null
    },
    {
        "SecondProcessorConnected": null
    },
    {
        "ConfiguredRouting": null
    },
    {
        "TestPayment": null
    },
    {
        "IntegrationMethod": {
            "integration_type": "test_type"
        }
    },
    {
        "ConfigurationType": null
    },
    {
        "IntegrationCompleted": true
    },
    {
        "StripeConnected": null
    },
    {
        "PaypalConnected": null
    },
    {
        "SPRoutingConfigured": null
    },
    {
        "Feedback": {
            "email": "[email protected]",
            "description": "Test Feedback",
            "rating": 5,
            "category": "test"
        }
    },
    {
        "ProdIntent": null
    },
    {
        "SPTestPayment": false
    },
    {
        "DownloadWoocom": false
    },
    {
        "ConfigureWoocom": false
    },
    {
        "SetupWoocomWebhook": false
    },
    {
        "IsMultipleConfiguration": false
    },
    {
        "IsChangePasswordRequired": false
    }
]
