Check a DPD IPN notification before acting on its contents
Have Notis pass the parameters received in a webhook back to DPD for authenticity verification, then report the outcome.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Verify DPD IPN Notification
Verifies whether an IPN notification came from DPD.
Why this helps
Treating an unverified notification as trustworthy can lead to decisions based on a request that was not validated.
- Verify a DPD IPN by posting back the parameters received.
- Keep validation results attached to the incoming request context.
- Make notification review more consistent.
Setup
Build it in a few focused steps.
- 1Connect AimTell and Dpd2 once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis in plain language from any channel.
- 3In one instruction, ask Notis to verify the received DPD IPN by posting all parameters from the request and report the verification outcome.
- 4Choose a webhook trigger, then select where run reports should go.
- 5Test with one real DPD IPN POST and confirm the verification result.
Questions about this workflow
Can I use an AimTell webhook as proof of a DPD IPN?
No. The workflow only validates a DPD IPN when the request contains the parameters that DPD expects for verification. AimTell has no listed trigger events.
Should Notis act on the payload before verification?
Ask Notis to report the verification result and only rely on the notification after DPD confirms it.
