How can I prevent duplicate charge using Stripe and PHP? - php

Question

Recently i got duplicated payments with Stripe.
They told me to use Idempotent Requests.
I made some tests and i see the error message if i tried to refresh the browser for example.
But i don't know how to make the "next step" in case of error.
I mean if my client make a payment and there is a network issue, how to do with Stripe to retry and continu the process or how to display an error message and came back to the payment's page ?
My code for now:
\Stripe\Stripe::setApiKey("xxxxxx");
$charge = \Stripe\Charge::create([
'customer' => $customer->id,
'amount' => $total_payment,
'currency' => $currency,
'description' => $description
], ["idempotency_key" => $idempotency,]);
$chargeJson = $charge->jsonSerialize();
$status = $chargeJson['status'];
if($status=="succeeded") {...
Thank you for your help, if you can just give me some information and then it will help me to improve my code ^^

Here is a functional demo of the try/catch with all the possible errors adding "Idempotent Requests field", just add your own functionality in each catch:
try {
// Use Stripe's library to make requests...
$charge = \Stripe\Charge::create([
'amount' => $amount,
'currency' => "usd",
'description' => $description,
"receipt_email" => $mail,
], [
'idempotency_key' => $uniqueID
]);
} catch(\Stripe\Exception\CardException $e) {
// Since it's a decline, \Stripe\Exception\CardException will be caught
echo 'Status is:' . $e->getHttpStatus() . '\n';
echo 'Type is:' . $e->getError()->type . '\n';
echo 'Code is:' . $e->getError()->code . '\n';
// param is '' in this case
echo 'Param is:' . $e->getError()->param . '\n';
echo 'Message is:' . $e->getError()->message . '\n';
} catch (\Stripe\Exception\RateLimitException $e) {
// Too many requests made to the API too quickly
} catch (\Stripe\Exception\InvalidRequestException $e) {
// Invalid parameters were supplied to Stripe's API
} catch (\Stripe\Exception\AuthenticationException $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)
} catch (\Stripe\Exception\ApiConnectionException $e) {
// Network communication with Stripe failed
} catch (\Stripe\Exception\ApiErrorException $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
}
