Continuous testing for every endpoint you run.
Chain requests, assert responses, and get alerted the moment something breaks — via webhook or email.
A testing framework that never sleeps
Multi-Step Test Flows
Chain requests together like unit tests. Pass data between steps, validate responses with assertions on status codes, JSON fields, and response times.
Cron Job Monitoring
Your scheduled jobs ping Internalize when they run. If a ping is late or missing, you get alerted immediately — with configurable grace periods.
Smart Alerting
Set failure thresholds to avoid noise. Route alerts to email or webhooks with cooldown periods and recovery notifications when services come back.
Environment Management
Write a flow once, run it against staging, production, or dev. Store variables and secrets per environment — swap targets without changing tests.
Full Run History
Every test run is logged with request/response details, headers, timing, and assertion results. Drill into any failure to see exactly what went wrong.
Secrets & Variables
Store API keys, tokens, and base URLs securely. Reference them in any step with template syntax — secrets are encrypted and never exposed in logs.
Manage healthchecks on a virtual operations canvas
Lay out request flows, cron jobs, alert paths, and ownership metadata in one workspace built for production monitoring reviews.
Request map
See related flows and scheduled jobs as connected operations nodes instead of separate lists.
Health metadata
Select a node to review schedules, tags, owners, status, and last activity in context.
Incident context
Spot degraded healthchecks and jump directly to the flow or cron monitor that needs work.
Up and running in minutes
Build your test flow
Chain HTTP requests, add assertions on status codes and response bodies, and set a schedule.
We run it continuously
Internalize executes your flows on the cadence you set and evaluates every assertion automatically.
Get alerted on failures
When a test fails, you know immediately via email or webhook — not from a customer support ticket.
Not just uptime checks
Internalize can test any API behavior — combine requests, inspect responses, and alert on anything you can express as an assertion.
Detect downtime instantly
Hit your health endpoint every minute. If the status code isn't 200 or response time exceeds 2 seconds — get alerted before a single user notices.
GET /api/health → assert status = 200 → assert time < 2sMonitor business metrics
Query your API for new signups in the last hour. If the count drops to zero during business hours, something might be broken in your funnel.
GET /api/stats/signups?period=1h → assert body.count > 0Test authentication flows end-to-end
Log in with test credentials, use the returned token to hit a protected endpoint, and verify the response. Catch auth regressions before they ship.
POST /auth/login → GET /api/me (with token) → assert body.email existsVerify third-party integrations
Your payment provider, email service, or CDN can go down too. Test their endpoints on a schedule so you know about outages as they happen.
GET https://api.stripe.com/v1/charges → assert status = 200Catch stale data and broken jobs
Query an endpoint that depends on a background job. If the data hasn't updated in the expected window, your pipeline is stuck.
GET /api/feed/latest → assert body.updatedAt < 10min agoValidate webhook delivery
Send a test event to your webhook endpoint and verify it returns the right status. Make sure your integrations are actually receiving data.
POST /webhooks/ingest → assert status = 202 → assert body.queued = trueSimple, predictable pricing
