XF 2.1 Stripe payment is stuck on ‘Pending’

[Punt Road End]

My site is running 2.1.9, and added all the keys and made a successful payment but the donation is not registering and showing up on the forum after a successful payment. Btw I’m using Themehouse [TH] Donate.

I’ve added the API keys to our dev site and the live site, in Stripe I’ve disabled the live site to be able to test the dev site.

Checking the webhook attempts they have all failed since the payment.
