Hi There @jamieolney ,

Thank you for opening this issue. The 425 error is expected with Apple Pay. As Apple Pay goes to paid immediately, the first webhook already comes in before we receive the response from Mollie on creating the transaction. This led to different problems in the past, deciding us to delay the processing of this.

For the multiple “Registered notification about” messages: that is caused by multiple webhook calls that are successfully processed. That only occurs when the response of the webshop on the webhook is too slow. Usually, this can be mitigated by setting Stores -> Configuration -> Mollie -> Advanced -> Process transactions in the queue (experimental) to Yes.

we can also see these errors in sentry:

Hello @simonmaass, Please see my previous comment, also that error has to do with having a response too fast when paying using Apple Pay.

Hi @simonmaass,
Please let me know if this is now clear for you or if we can close this issue.
Thanks!
