Getting Started with Sentinel
Use Sentinel's API to score and block risky signups, allow, challenge, or block, before they reach your product.
Sentinel is ChatFlow's signup-protection service. You call its API with an email (and optionally an IP or domain), and it returns a risk decision, allow, challenge, or block, so you can stop fraudulent signups before they ever reach your product.
Sentinel is a separate product
Sentinel has its own dashboard and login, distinct from your ChatFlow chatbot account. You sign up for it separately, a free trial is available.
Set up Sentinel
Create a Sentinel account
Sign up and complete onboarding from the Sentinel area, using its own sign-up rather than your ChatFlow login. Choose a plan to get started.
Create an API key
In the Sentinel dashboard, open API Keys and create a key. You can test the key right there, enter an email and view the risk response.
Call the check endpoint
Send an email, and optionally an IP or domain, to the check endpoint with your API key. The response includes a risk decision you can act on in your signup flow: allow, challenge, or block.
Tune with custom lists
Use Custom Lists to maintain your own blacklist and whitelist, with bulk CSV import and export, so known-bad or known-good addresses are always handled the way you want.
Monitor
- The dashboard shows total checks, plus blocked, challenged, and allowed counts, with trends and top blocked domains.
- The Activity Log holds the full request history with search, filters, and CSV export.
What's next
- Add Sentinel's check to your signup or registration flow so every new account is scored.
- Review the Activity Log regularly and adjust your custom lists as fraud patterns change.
