Error string indice must integers Json

[snippsat]

No encoding,as mention so is Requests doing that.
If the url return json,then this should work.

import requests

response = requests.get("http://www.testecliente.com.br/ApiTeste/GetDadosCartaoCliente?CL_COD=1")
# Get json,a json encode/decode is build in
json_data = response.json()
# Should be a dictionary
print(type(json_data_data))
# Look at data
print(json_data)
