Testeando la conección desde Odoo con Mercadolibre

curl -X GET https://api.mercadolibre.com/categories/MLA5725

En la cual queremos obtener la lista de categorias. Si la conección con el server es la correcta, obtendremos el json con la lista de las categorias:

Ahora, supongamos que podemos obtener la lista de categorias... el paso siguiente es obtener el ID del Vendedor de la cuenta y el token ID de la misma (ver la documentacion del API de MercadoLibre sobre como hacerlo). El paso siguiente es, testar con dichas credenciales la conección. Para eso se puede buscar la lista de items posteados en la cuenta con otra sentencia CURL:

curl -X GET https://api.mercadolibre.com/users/<seller ID>/items/search?access_token=<access token>

En la cual deberán reemplazar los datos del seller_id y el access token. Si la configuración de la cuenta tiene error, les dará el siguiente mensaje de error:

{"Error": "The specified resource is not available at the moment."}
