Automated Tag Management via Webhook
A webhook-driven workflow that receives an email address, a tag and an action. It validates that the email was supplied and returns an error if not; when present it fetches the corresponding contact from Mautic, confirms the contact exists, and applies the add or remove operation.

01 — The problem
Tagging drives segmentation, and segmentation drives campaigns. When tagging is manual it is applied late and inconsistently, and the resulting segments quietly stop meaning anything.
02 — Our solution
A small, strict endpoint that any system can call to tag a contact. It refuses malformed requests, verifies the contact exists before mutating anything, and performs exactly the requested operation.
How it works
The pipeline, step by step — from the first input to the final output.
- 01
Webhook intake
A request arrives with email, tag and action (add or remove).
- 02
Input validation
A missing email returns an error immediately.
- 03
Contact lookup
The contact is fetched from Mautic by email.
- 04
Existence check
The flow confirms the contact exists before attempting a change.
- 05
Tag operation
The tag is added or removed and the result is returned.
What we built
The outcomes
01
Tagging happens at the moment the triggering event does
02
Segments stay consistent because tagging is no longer manual
03
One endpoint reused across integrations
Challenges we solved
Guarding a shared endpoint
Anything callable by many systems will eventually be called wrongly. Validation and existence checks are the whole point of the design.
