Buenas tardes ,  
si alguien me pudiera ayudar con un error de formato json.

Estoy creando un cliente con ciertos parámetros pero a la hora de enviar , me sale el  
mensaje **(Malformed JSON string).**

{“session\_id”:“a0ff5bd015481e0c727136998954af7f”}  
{“customer\_info”:{“name”:“sistemasflx”,“login”:“eperalta”,“password”:“eperalta17”}}

@eduardo7: Welcome to the community. I translated your message and hope you are trying to do the below:

"Good afternoon ,  
if someone could help me with a json format error.

I am creating a client with certain parameters but when sending, I get the  
message (Malformed JSON string)."

Can you please provide more details? Please ensure that the params are correct. Also Ensure you have added the correct “Content-Type” in the headers.

¿Puedes intentar usar tu JSON como un tipo de cuerpo sin formato en la solicitud? Algo parecido a la siguiente captura de pantalla:

El mensaje de error significa que el formato en el que está pasando los datos es incorrecto, lo que me hace pensar que pasarlo en este formato podría ayudar.

Gracias estimados,

pude consumir la api correctamente , el problema era el formato del json tuve que utilizar una aplicativo para limpiar el json.
