    The request was well-formed but was unable to be followed due to semantic errors

2. Payment confirmation

We will send you operation responce via already sent "webhook_url".

• Method POST

• Headers :

    Signature

• Body :

    invoice with payment status

• Signature Validation :

    Incoming webhook request has a header that can be used to verify the payload
    The name of the header containing the signature can be configured in the 'Signature' header key to validate signatures

• This is an example how you will compute the signature in PHP

    //Secret key can be found in your profile information
    $secret = "API_SECRET";
    //get incoming webhook request body content
    $body_content = file_get_contents("php://input");
    //
    $computed_signature = hash_hmac('sha256', $body_content,$secret);
    //get signature from header
    $signature = getallheaders()["Signature"];
    //check computed signature
    $validated =  hash_equals($computed_signature, $signature);// : bool

    if($validated){
        $payment = json_decode($body_content,true);
        //@Todo: check invoice status first ($payment["invoice"]["status"] === 'paid')
        if($payment["invoice"]["status"] === 'paid'){
            //@Todo: confirm order
        }elseif($payment["invoice"]["status"] === 'failed'){
            //@Todo: do anything when payment failed
        }
    }
    exit;
