Paymill subscription in PHP - php

Question

I am trying to create a subscription i Paymill. Ive read through their examples but i do not seem to get it.
All i really want to do is to setup a subscription, here is my current code:
$token = $_POST['paymillToken'];
if ($token) {
require "Services/Paymill/Payments.php";
require "Services/Paymill/Transactions.php";
require "Services/Paymill/Subscriptions.php";
require "Services/Paymill/Offers.php";
$params = array(
'amount' => '49900', // Cent!
'currency' => 'SEK', // ISO 4217
'token' => $token,
'description' => 'User ID# ' . $userIdMain . ' Email: ' . $userEmail
);
$transactionsObject = new Services_Paymill_Transactions(
PAYMILL_API_KEY, PAYMILL_API_HOST
);
$transaction = $transactionsObject->create($params);
echo "<br /><br />";
print_r($transaction);
echo $transaction['client']['id'];
echo $transaction['payment']['id'];
$params = array(
'client' => $transaction['client']['id'],
'offer' => 'offer_9cdffb501f565bf827a8',
'payment' => $transaction['payment']['id']
);
$subscriptionsObject = new Services_Paymill_Subscriptions(PAYMILL_API_KEY, PAYMILL_API_HOST);
$subscription = $subscriptionsObject->create($params);
echo "<br /><br />";
print_r($subscription);
}
The problem is that the above create two payments at once. But it seems like the subscription object requires me to first have a payment_id (see $transaction['payment']['id'] above).
What am i doing wrong here?

Answer 1

Creating a subscription will also create a transaction, which is correct. Add a Payment Object ( https://www.paymill.com/en-gb/documentation-3/reference/api-reference/#create-new-credit-card-payment-with ) instead of creating a new transaction and pass the id to the Subscription->create().

OK it's not PHP but I had the same kind of uncertainty following the right steps to set up a subscription. In the end it's kind of easy, so I am posting my code so far in case it helps.
The app is MVC .net and I am using the PayMill PayButton to generate a payment token. This is part of the model during the registration process. The following code calls the .net wrapper of the PayMill API.
private static async Task<Subscription> MakePayMillSubscription(int amount, ApplicationUser user, PaymillContext paymillContext, Payment payment, Client client)
{
SubscriptionService subscriptionService = paymillContext.SubscriptionService;
Subscription subscription = await subscriptionService.CreateAsync( payment, client, null, amount, "EUR", Interval.periodWithChargeDay(1, Interval.TypeUnit.MONTH), null, user.Id, Interval.period(10, Interval.TypeUnit.YEAR));
return subscription;
}
private static async Task<Client> MakePayMillClient(RegisterViewModel model, ApplicationUser user, PaymillContext paymillContext)
{
ClientService clientService = paymillContext.ClientService;
Client client = await clientService.CreateWithEmailAndDescriptionAsync(
model.Email,
user.Id
);
return client;
}
private static async Task<Payment> MakePayMillPayment(RegisterViewModel model,PaymillContext context, Client client)
{
Payment payment = await context.PaymentService.CreateWithTokenAndClientAsync(model.paymillToken, client);
return payment;
}
Then I call these during registration like this at the moment (I am still in a testing phase)
client = await MakePayMillClient(model, user, paymillContext);
payment = await MakePayMillPayment(model, paymillContext,client);
subscription = await MakePayMillSubscription((int)(account.TotalAmountDue * 100.0M), user, paymillContext, payment, client);
