在Paypal上重复付款的第一笔付款

Question

I'm currently setting a recurring paypal payment. I'm not sure to understand when the first payment is done. In my case, I want to first payment to be done when the user subscribe, and automaticaly renew after 3 month. I'm not sure if the " INITAMT " parameter if the good way to do that.

Moreover, when I try to set the parameter " INITAMT " in sandbox, the résulting profile is always " PengindProfile "

Here is my parameters :

'METHOD' => 'CreateRecurringPaymentsProfile',
'TOKEN' => $token,
'PAYERID' => $payerId,
'USER' => $user,
'SIGNATURE' => $signature,
'PWD' =>$password,
'VERSION' => 74.0,
'PROFILESTARTDATE' => gmdate("Y-m-d\TH:i:s\Z"),
'DESC' => 'My subscription',
'BILLINGPERIOD' => 'Month',
'BILLINGFREQUENCY' => '3',
'AMT' => 10,
'CURRENCYCODE' => 'EUR',
'PAYERID' => XXX,
'MAXFAILEDPAYMENTS' => 3,
'INITAMT' => 10

And a finale question, how does the reccuring Payment works ? Paypal send the money on my account each 3 month ? It is possible to get a notification on a PHP serveur to update the subscription status ?

Thanks for your help !

I'd definitely look into using the PayPal PHP SDK instead of trying to use their REST API directly or via some minimal library. Their SDK provides much convenience working with the service and has plenty of use-case based examples including recurring billing and subscriptions.
