Add consenting event registrants to your Doppler list
Connect your registration system's webhook to Notis and add a registrant to Doppler only when their request includes the information and email permission you require.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add Subscriber
Tool to add a new subscriber to a specific list for a specified account.
Why this helps
Manually moving event registrations into an email list creates delays and can blur the difference between registering and opting in.
- Process registrations without manual re-entry.
- Require the registration request to include email consent.
- Send registrants to the event list you name.
Setup
Build it in a few focused steps.
- 1Connect Doppler once in the Notis portal and connect the system that will call your webhook.
- 2Create an automation in the portal or tell Notis what outcome you want from any channel.
- 3In one instruction, name the account and list, and add only requests with email and explicit marketing consent.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real registration request that includes opt-in.
Questions about this workflow
What starts this workflow?
A webhook trigger starts when an HTTP request reaches the Notis automation. Your registration system must send the request.
Will registration alone count as email consent?
No. The instruction should require explicit marketing consent in the request before adding a subscriber.
