php mollie payments recurring billing - php

Question

My code is :
$customer = $mollie->customers->create([
"name" => $name,
"email" => $email,
]);
$customer->createSubscription([
"amount" => [
"currency" => 'USD',
"value" => 20.00,
],
"interval" => '2months',
"times" => 3,
"description" => $someDescription,
"webhookUrl" => $webhook,
"method" => NULL,
]);
$payment = $customer->createPayment([
"amount" => [
"currency" => 'USD',
"value" => 20.00,
],
"description" => $someDescription,
"redirectUrl" => $siteUrl,
"webhookUrl" => $webhook,
"metadata" => [
"order_id" => $orderId,
],
"sequenceType" => \Mollie\Api\Types\SequenceType::SEQUENCETYPE_FIRST,
]);
The result is:
Fatal error: Uncaught exception 'Mollie\Api\Exceptions\ApiException'
with message 'Error executing API call (422: Unprocessable Entity): No
suitable mandates found for customer. Field: customerId.
Is something that I missing??

Answer 1

You're missing the customer ID for the customer you created previously.
$payment = $customer->createPayment([
"customerId" => $customer->id, /* see #3 in documentation */
"amount" => [
"currency" => 'USD',
"value" => 20.00,
],
"description" => $someDescription,
"redirectUrl" => $siteUrl,
"webhookUrl" => $webhook,
"metadata" => [
"order_id" => $orderId,
],
"sequenceType" => \Mollie\Api\Types\SequenceType::SEQUENCETYPE_FIRST,
]);

Answer 2

I find an answer on my own question:
In order to add a subscription for an user you must first add the payment and after that the subscription.
$customer = $mollie->customers->create([
"name" => $fullName,
"email" => $email,
]);
$payment = $customer->createPayment([
"amount" => [
"currency" => $currency,
"value" => $amount,
],
"description" => $description,
"redirectUrl" => $siteUrl,
"webhookUrl" => $webhook,
"metadata" => [
"order_id" => $orderId,
],
"sequenceType" => \Mollie\Api\Types\SequenceType::SEQUENCETYPE_FIRST,
]);
$customer->createSubscription([
"amount" => [
"currency" => $currency,
"value" => $amount,
],
"times" => $recurringLimit,
"interval" => $interval,
"description" => $description,
"webhookUrl" => $webhook,
"method" => NULL,
]);
