You have to escape the { and } with {{ and }}. Also you can use interoplated string ($)

string userName = "userName";
String orderStr = $@"{{
      ""currency"":""MXN"",
      ""customer_info"": {{
        ""name"": ""julio"",
        ""phone"": ""Cabalos"",
        ""email"": ""[email protected]""
      }},
      ""line_items"": [{{
        ""name"": ""\'{userName}\'"",
        ""description"": ""descripc"",
        ""unit_price"": 233,
        ""quantity"": '1',
        ""tags"": [""Transporte"", ""Logistic Cloud""],
        ""type"": ""physical""
      }}],
     ""charges"":[{{
        ""payment_method"": {{
          ""type"": ""oxxo_cash""
        }}
      }}]
   }}";
