Workflows
for anything
A visual builder for the "run this on a schedule / on a webhook / when something happens" workflows you'd otherwise write a cron job, a Zapier zap, or a bash script for. HTTP calls, routers, waits, notifications, sends — on one canvas, with real-time testing and variable passing between every step.
Click Test and watch your workflow actually run
Waits wait. HTTP calls fire. Each step's output feeds the next. The canvas lights up exactly as a real run would experience it.
Eight building blocks,
infinite workflows
Triggers
Start on a schedule (cron + timezone), a webhook from any system, or one of the built-in contact events. Your flow fires when reality matches.
Wait
Pause anywhere from seconds to 30 days. BullMQ parks the job and wakes it up on time — no cron you have to maintain.
Router
Route on any variable — HTTP response bodies, workspace stats, webhook payloads, anything earlier steps emit. One predicate, many paths.
HTTP request
Call any external API. Store the response body, pull out specific fields as named variables, and reference them anywhere downstream.
Send email
Static body or a template. Fire immediately or schedule for a future time — natural-language ("tomorrow at 2pm") parsed by AI.
Notify team
Email one or many teammates. Severity bands (info / warning / critical) — perfect for ops alerts, daily digests, or failure escalations.
Workspace stats
Load your own platform metrics (send volume, delivery rate, error counts, …) into variables. Build health checks and SLA monitors.
Tags + properties
Update contact records when a flow is scoped to a contact. Silently skipped for scheduled / API-driven flows that don't need them.
Built for whatever
you run
Ops monitors, webhook handlers, internal tooling, contact journeys — the same primitives cover all of them.
Ops alerts
Every 15 min: fetch uptime stats → router branches on status → Slack-email the on-call if deliverability drops.
Daily digests
Weekdays at 8am: pull yesterday's numbers from your DB via HTTP → compose a summary → email the team.
Webhook handlers
Stripe / GitHub / custom system POSTs → parse payload → route on the event type → fire the right side-effect.
Contact journeys
Contact added / tag applied → personalized email, wait a day, check if they converted, branch accordingly.
Data syncs
Schedule → call your source API → transform the response → push each record to a destination API. No Zapier middleman.
Internal tooling
Webhook from an internal form → validate → route on approvals needed → notify the right person with the right context.
Build it, test it,
ship it
Pick a trigger
On a schedule, a webhook call, or a contact event — whatever kicks the work off for your use case.
Drag in steps
HTTP calls, routers, waits, notifications, sends. Every step's outputs become merge-tag variables for later steps to use.
Test it real
Click Test — a real run fires with real timing. 10-minute waits actually wait 10 minutes; the canvas animates as each step executes.
Watch it run
Run history shows every run, which step each one is parked on right now, when it'll resume, and every output along the way.
One canvas, many branches
The Router step can split into as many branches as you need. First match wins; default catches the rest. No confusing "else trees".
Real-time test runs
Test runs actually fire — BullMQ pauses on wait steps exactly like production. The canvas animates step-by-step so you see the real timing.
Any API, any data
HTTP steps hit any endpoint, extract specific fields as named variables, and feed them into downstream routers, sends, or notifications.
Step-level error handling
Fail-soft on flaky third-party APIs. Each HTTP / email / webhook step can continue, exit, or fail on error — configurable per step.
Merge tags everywhere
Any step's output is a variable. Reference `{{http.response.status}}` in a router, or `{{stats.delivery_rate_today}}` in a notification subject.
Self-documenting flows
Notes live on every step. A new teammate opens the flow and sees exactly why each branch exists, right on the canvas.
Native n8n integrationAlready building on n8n? We ship an official node.
n8n-nodes-posthawk is a community node package on npm — one action node and one trigger. Install it in any n8n instance, paste your Posthawk API key, and every Posthawk primitive slots into your n8n workflows as a first-class step.
