Why this helps
Manually checking whether an IPN post is authentic adds friction to time-sensitive operations.
- Submit all original POST parameters for verification.
- Make the validation result easy to review.
- Reduce manual steps in an IPN handling process.
Setup
Build it in a few focused steps.
- 1Connect DPD in Notis once.
- 2Create an automation and instruct Notis to validate the original parameters from each IPN post.
- 3Pick a webhook trigger that receives the post from your Ably-connected service.
- 4Choose where run reports should go.
- 5Test with one real IPN request.
Questions about this workflow
Which data should the request include?
Include all parameters that were originally POSTed to your site so the IPN verification action can submit them to DPD.
Does this workflow process or update the purchase?
No. The listed action verifies the IPN post; it does not modify purchase records.
