Check whether a certificate recipient is already in Doppler
A quick existence check helps prevent duplicate subscriber work when certificate recipients enter a follow-up process.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check Subscriber Exists
Checks whether a subscriber exists in an account.
Why this helps
Looking up recipients by hand adds friction and can lead to duplicate subscriber handling.
- Checks subscriber existence without retrieving full subscriber details.
- Makes a follow-up decision easier to route.
- Avoids treating every certificate recipient as a new subscriber.
Setup
Build it in a few focused steps.
- 1Connect Accredible certificates and Doppler once in the Notis portal.
- 2Create an automation and ask Notis to check Doppler for the recipient email supplied in the request.
- 3Choose the webhook trigger and arrange for the credential workflow to send the recipient email.
- 4Choose where run reports should go, then test with one real recipient.
Questions about this workflow
Does this retrieve the subscriber's full profile?
No. This action checks whether the email exists in the Doppler account.
Does a positive result mean the person opted in?
No. Existence is not proof of marketing consent. Use a separate verified consent source before adding or messaging someone.
What starts this workflow?
A Notis webhook starts it when an external system sends a request with the recipient email.
