Providers retry when you respond slowly (Slack: 3s, Shopify: 5s) — and retries mean duplicates. This ACKs with 200 immediately, then does the slow work with retries, and alerts Slack only if everything fails.

How this workflow works

  1. 1. Provider webhook

    trigger

    Starts the workflow — from an inbound HTTP request or on a schedule.

  2. 2. ACK in <1s

    respond-webhook

    Sets the HTTP response returned to whoever called the workflow URL.

  3. 3. Slow downstream call

    http-resilient

    HTTP request with retries, backoff, and jitter. ⚠ On success the response body replaces the payload.

  4. 4. Alert on final failure

    slack

    Failure path — runs only when the previous step fails after retries.

    Posts a message to a Slack channel via an incoming webhook.

Run it without writing any code

Every step above is a visual node in the Requex workflow builder. Clone this template, fill in your own credentials where a step needs them, and it runs in the cloud — no server, no cron box, no npm install. Webhook-triggered workflows get an always-on URL; scheduled ones run on your cron expression.
