Two Ways to Integrate
Choose the integration method that fits your architecture. Both methods share the same enrichment pipeline and produce a unified risk score with explainable reason codes.
Form Fraud Protection
Client-side JavaScript integration
Add one script tag to any page with a form. Every submission is intercepted, scored across all intelligence signals, and classified by risk level. Your team reviews results in the dashboard or receives them via webhook.
Best for
- Public web forms and landing pages
- Lead capture and contact forms
- No-code and low-code sites (Webflow, Framer, WordPress)
- Teams that want zero backend changes
Signals analyzed
Behavioral signals included automatically
Fraud Protection API
Server-to-server REST endpoint
Your backend sends submission data and receives a complete risk assessment in the API response. Full backend control: apply your own logic, accept, flag, or reject based on the score. Works for SaaS registrations, mobile apps, and any backend-driven flow.
Best for
- SaaS registration and onboarding flows
- Mobile apps and API-first architectures
- Backend workflows and batch processing
- Teams that own their submission pipeline
Signals analyzed
Behavioral signals available in hybrid mode (deploy JS client alongside API)
Hybrid Mode: Maximum Signal Coverage
Deploy the JS client on your frontend and pass the opportifyToken to your API request. The API resolves the session and incorporates behavioral signals (typing patterns, automation detection, device fingerprinting) into the synchronous risk assessment.
Detect Risk in 4 Simple Steps
Add one snippet. Get explainable risk signals.
Add the Snippet
Paste 3 lines of JavaScript onto your form page. No backend changes, no SDK to configure — done in minutes.
Protect Your Forms
Create a Form Endpoint in the dashboard and point your form to the secure submit URL. The snippet handles everything else automatically.
Review by Risk Level
Every submission arrives pre-scored and classified. Your dashboard shows all submissions segmented by risk — no manual triage needed.
Act on the Score
Route clean, low-risk submissions to HubSpot, Salesforce, Slack, or any webhook receiver. Review, flag, or reject high-risk and suspicious submissions before they reach your CRM — your team stays in control.

Frequently asked questions
How does Fraud Protection work?
Form Fraud Protection: A lightweight JavaScript snippet collects device fingerprints, behavioral signals (typing cadence, scroll patterns, automation detection), and session metadata. This is fused with email, IP, and phone intelligence to produce a risk score (200–1000) with explainable reason codes, delivered via webhook.
Fraud Protection API: Your backend sends submission data to
POST /intel/v1/fraud/analyze and receives a complete risk assessment synchronously: email, IP, phone, content, velocity, and geographic signals in a single response. For maximum signal coverage, deploy both together (hybrid mode) to add behavioral intelligence to API scoring via the opportifyToken.Does it only detect automated submissions?
It also identifies suspicious or manipulated submissions that appear human, including click farms, automated form fills using real user data, repeated low-quality leads, and adversarial traffic designed to exhaust ad budgets or pollute CRMs.
The system focuses on detecting signals of manipulation and risk, not just whether a submission is human.
Is it really invisible to users?
How is it different from CAPTCHA?
What does it detect?
It also detects low-intent or adversarial submissions, including click farms, reused personal data, and activity designed to drain ad budgets or pollute pipelines.
Does it require cookies to work?
Analysis runs on behavioral signals, device and browser characteristics, network data, and submitted information. If cookies are available, they can be used as an additional signal, but the system works fully without them.
Will this impact site performance or page speed?
It does not introduce heavy dependencies and is comparable in size and impact to standard analytics scripts.
How long does integration take?
Fraud Protection API: Generate your API key, send a
POST request to /intel/v1/fraud/analyze with your submission fields, and parse the synchronous JSON response. Most backend integrations are complete in under an hour.How do teams justify the cost?
Invalid or low-quality submissions can trigger unnecessary automations, inflate CRM costs, and reduce the efficiency of paid campaigns. By filtering these before they enter your systems, teams typically see cleaner data, more reliable reporting, and less wasted spend.
What's the pricing?
Is there a free trial?
What signals does the API return in a response?
score (200–1000), level, and factors (the top reason codes), plus a sources object with a detailed breakdown per intelligence source:email (deliverability, disposable and free detection, domain age, blocklist, SPF/DKIM/DMARC), ip (connection type, geolocation, VPN/proxy/datacenter, blocklist), content (gibberish and spam scoring), session (behavioral signals, available in hybrid mode), velocity (submission frequency windows), and geo (geographic consistency across IP, phone, and email). Each source carries its own score, so you see not just the verdict but why.
How is the risk score calculated and what do the levels mean?
lowest (≤300), low (301–400), medium (401–600), high (601–800), and highest (over 800).The levels are advisory. We surface the risk and the reason codes behind it; your team decides the thresholds at which you allow, review, flag, or challenge a submission.
What is hybrid mode and when should I use it?
opportifyToken and opportifyFormUUID from the form.This gives you the maximum signal coverage. The API alone scores email, IP, content, velocity, and geographic signals. Hybrid mode adds the behavioral layer captured by the client: typing cadence, automation detection, honeypot triggers, submit timing, and device fingerprint consistency. Use it when you control your own backend and want behavioral intelligence combined with synchronous scoring.
Does it detect repeated abuse from the same source?
Geographic consistency checks add another layer by cross-referencing the country signals from the IP, the phone number, and the email domain. Mismatches, for example an IP in one country and a phone code in another, raise the risk profile even when each individual signal looks clean.
What about false positives?
Every score ships with structured reason codes, so when a submission is flagged you can see exactly which signals contributed. That transparency lets you tune your review thresholds to your own risk tolerance rather than trusting an opaque verdict.
Does it replace my existing security stack?
Many teams run it in front of KYC to filter obvious fraud and synthetic identities first, which reduces unnecessary verification costs. It works as a standalone layer or as an enrichment step feeding your existing review and routing workflows.
