I get the following error when trying to send a message with an interactive card created in Chat App Card Builder.

\<?xml version="1.0" encoding="UTF-8" standalone="yes"?\> `300` Request Body should be a valid JSON object.

I’m using this URL: [https://api.zoom.us/v2/chat/users/](https://api.zoom.us/v2/chat/users/)“my user”/messages

The JSON of the message is this:  
{  
“message”:“Mensagem de avaliação do pedido número 123456”,  
“[to\_contact":"XXXXX@XXXX.com](mailto:to_contact%22:%22XXXXX@XXXX.com)”,  
“interactive\_cards”:[  
{  
“card\_json”:  
{  
“content”:  
{  
“settings”:{},  
“head”:  
{  
“text”:“Avaliação de atendimento”,  
“style”:  
{  
“bold”: true  
},  
“sub\_head”:  
{  
“text”:“Referente ao pedido nº 123456”  
}  
},  
“body”:[  
{  
“type”:“section”,  
“layout”:“horizontal”,  
“sections”:[  
{  
“type”:“message”,  
“text”:“De forma geral, qual foi sua percepção sobre esse atendimento?”  
},  
{  
“type”:“radio\_buttons”,  
“action\_id”:“radio\_action”,  
“options”:[  
{  
“text”:“Ruim”,  
“value”:“value1”  
},  
{  
“text”:“Normal”,  
“value”:“value2”  
},  
{  
“text”:“Boa”,  
“value”:“value3”  
},  
{  
“text”:“Excelente”,  
“value”:“value4”  
}  
]  
},  
{  
“type”:“message”,  
“text”:“Com relação ao técnico, como foi a qualidade do seu atendimento?”  
},  
{  
“type”:“radio\_buttons”,  
“action\_id”:“radio\_action”,  
“options”:[  
{  
“text”:“Ruim”,  
“value”:“value1”  
},  
{  
“text”:“Normal”,  
“value”:“value2”  
},  
{  
“text”:“Boa”,  
“value”:“value3”  
},  
{  
“text”:“Excelente”,  
“value”:“value4”  
}  
]  
}  
]  
},  
{  
“type”:“actions”,  
“items”:[  
{  
“text”:“Avaliar”,  
“value”:“primary”,  
“style”:“Primary”  
}  
]  
}  
]  
}  
}  
}  
]  
}

If I remove the part: “interactive\_cards”:[{}], the message is sent, but without the interactive card, a simple message is sent Despite removing the interactive card element, the content/settings-head-body child elements remain.

Using the Bot gives the same error.
