Stripe "idempotent requests"

Greetings,

 I'm interested in Stripe's "idempotency" key to prevent duplicate transactions ( stripe.com/docs/api/idempotent_requests ). Does the Stripe plugin for Payment Form use the Omnipay API?

Kind Regards,
Jay

Hello Jay

Yes. It uses Omnipay API

Hi Tuan,

It appears the existing Stripe plugin would need to be updated to the Omnipay 3 library in order to use the idempotency key. Is that something you could do for us? If so, please quote a price.

Thank you,
Jay

Hello Jay

I haven't looked at the details yet but we have omnipay3 available to use in case you want to try joomdonation.com/downloads/lib_omnipay3.zip (we made this library in case someone wants to use our extensions with PHP 8)

Maybe you can install the updated library and give the modification a try? Are you using Stripe or Stripe Checkout?

Tuan

Tuan,

Thank you for the Omnipay3 link. I'm using the basic Stripe 5.4.1 plugin.

I'll install the library and take a look over the weekend. But I'm an asp.net/VBScript programmer. My PHP game is pretty weak!

Best,
Jay

OK Jay. When I have sometime, I might look at it, too. This week, I'm quite busy.

Hello Tuan,

Sorry for not replying sooner but I got involved with some other projects. I've finally looked over the Omnipay 3 library and what might be involved to implement the idempotency keys, and I'm afraid this is way beyond my skill set. We're getting duplicate transaction about 5% of the time and having to issue refunds. Of course, we still get charged the merchant fee from Stripe for the duplicates!

We would be very interested in having you implement this feature for us. Please let me know what that would entail.

Best,
Jay

Hello Jay

I don't have time to look at this right now. But I added it to my todo list and will see if I can find sometime to look at it next week

Tuan

Tuan,

Here is a video that Stripe just put out regarding Idempotency. We're currently averaging about 2% duplicate charges with Stripe so would be very interested to see this implemented in Payment Form.


Thanks,
Jay

Bump - I'm interested in this feature too:
stripe.com/docs/api/idempotent_requests

So far this year I have $10 in extra stripe fees because of the issue -

[Edit]
Actually, I see this new setting in the Payment Form configuration: Prevent Double Submissions
I'm going to enable this and see if it helps - maybe it's already solved.
