Frequently asked questions
Every product, pricing, and integration question we get, gathered in one place.
How do I fix a 429 "Too Many Requests" error on outbound webhooks?
A 429 usually means you're sending bursts faster than the receiver's rate limit allows. Jitterflow spreads each burst across a computed delay window before dispatch, so requests land at a sustainable pace instead of all at once — no changes to your sending logic, just point deliveries at a Jitterflow endpoint.
What is a webhook dead-letter queue?
A dead-letter queue (DLQ) holds webhook deliveries that failed every retry attempt so they can be inspected and manually retried, instead of disappearing. Every Jitterflow endpoint gets a hosted DLQ out of the box, with an API to list, retry, or resolve failed jobs.
Can I use Jitterflow with n8n, Make.com, or Vapi?
Yes. Jitterflow ingests webhooks over a plain HTTP POST, so anything that can call a webhook URL can send through it — including n8n, Make.com, Zapier, Vapi, and Retell. Point the tool's outgoing webhook at your Jitterflow ingest URL instead of the final destination, and Jitterflow handles jitter, retries, and the DLQ before forwarding it on.
Is Jitterflow just a hosted job queue?
Underneath it's a Redis-backed job queue, yes — but Jitterflow adds the parts you'd otherwise have to build yourself: computed jitter windows to avoid rate limits, per-destination isolation so one slow endpoint doesn't block the rest, SSRF-safe URL validation, and a real dead-letter queue with a resolve/retry API.
How much does Jitterflow cost?
Start free on the Developer tier (2 req/s, 5,000 webhooks/mo), then scale up as needed: Pro at $19/mo (5 req/s), Team at $59/mo (25 req/s), Enterprise at $199/mo (100 req/s) — plans with a free trial include one, and annual billing saves on every paid tier. Paid tiers that go over their monthly quota pay a small per-webhook overage fee instead of being cut off. Full breakdown on the pricing page.
Is there a free trial on Jitterflow?
Every plan starts with a 14-day trial, including the free Developer tier — no credit card required to sign up. On paid plans, that's 14 days before your card is charged. On the free Developer tier, upgrading before the trial ends keeps your account running without any interruption.
What happens if I go over my monthly webhook quota?
Pro and Team meter overage automatically at $0.50 per 10,000 extra webhooks, billed via Stripe — no hard cutoff. Enterprise overage is contract-negotiated. The free Developer tier has no self-serve overage: ingest is capped at 5,000/mo until you upgrade.
Can I switch plans anytime?
Yes — upgrade or downgrade at any time from the dashboard; billing is prorated by Stripe for the current cycle.
Is annual billing cheaper?
Yes, on every paid tier — annual billing saves 20% versus paying monthly.
Is there an official Zapier or Make.com app?
Not yet — n8n has a published community node (n8n-nodes-jitterflow), but Zapier and Make.com aren't packaged as native apps. Both work today through their built-in webhook actions: point Zapier's Webhooks step or Make's HTTP module at your Jitterflow ingest URL. See the Zapier and Make.com integration guides for the exact setup.
How do I verify a webhook signature from Jitterflow?
Every delivery can carry two independent, opt-in signature schemes at once: a legacy HMAC-SHA256 header, and Standard Webhooks-compatible headers (svix-id, svix-timestamp, svix-signature) — the same format OpenAI, Twilio, and Supabase already sign their own webhooks with. Set an outboundSecret on the endpoint to turn signing on; full verification code is on the signature verification guide.
