Receive JSON POST with PHP

Question

I’m trying to receive a JSON POST on a payment interface website, but I can’t decode it.

When I print :

echo $_POST;

I get:

Answer 1

Try;

$data = json_decode(file_get_contents('php://input'), true);
print_r($data);
echo $data["operacion"];

From your json and your code, it looks like you have spelled the word operation correctly on your end, but it isn't in the json.

EDIT

Maybe also worth trying to echo the json string from php://input.

echo file_get_contents('php://input');
