Transaction ID

Hi there.

Could you please help me clarify something?

I created a recurring payment plugin based on the os_authnet one. I had to make some changes in the core files also, so the new payment type is included everywhere. My payment processor is expecting some unique id when the data is sent to them, eg like an invoice number. From what I can see, Membership PRO does not create an invoice or unique id for the transaction till after data is sent to the payment processor. Is this correct? Or if not, where can I grab this value so I can use it in the the data that I am sending to the payment processor?

How does the system then know the payment was successful when data returns to the callback url from the payment processor? I mean, what value is used to lookup the correct transaction? Also, on recurring transactions, there has to be a way for the system to lookup which payment is being renewed. Will the system them use the transaction id supplied by the payment processor, and what is used for an invoice number?

Could you please clarify this?
Thanks!

I'll attempt to answer part of my own question. When I do a data dump of the $row variable inside processRecurringPayment function, I can see there is a $row->transaction_id which generates a random number like: QF1LL5N7A0YZHRWL before the data is sent to the payment processor. I don't see any invoice numbers though? Where do I get the invoice number from, or is this only generated AFTER the payment was successful?

Hello Paul

You can use $row->id . It is ID of the subscription record and is unique for each subscription.

Don't use transaction_id, it will be replaced with transaction_id of returned by the payment gateway for the payment later

For invoice_number, it is an sequence number and only be generated after payment completed
