STACKSYNC FEATURES

Build your Integration Layer.

Four composable modules — triggers, two-way sync, workflows and managed queues — that replace the stack of MuleSoft, Fivetran, Kafka and Zapier you’ve been stitching together.

TRIGGERS

Guaranteed Trigger Delivery
from any system

Stacksync triggers are simultaneously backed by both webhooks and polling to guarantee Lossless and Real-time CDC from any system.

Start integrating in no-code
  1. 01 Networks fail, services crash. Stop relying on unreliable webhooks for mission-critical workloads
  2. 02 Resume workflows automatically, never lose data even after a downtime
  3. 03 Fully observable and scalable events infra
Trigger your workflow
Your workflow is triggered by webhook.
Trigger the workflow by executing the following HTTP request direct below or copy/pasting it in your terminal. 
curl --request 'POST' \
--url 'https://usrv.api.workflows.stacksync.com/
workspaces/2943/workflows/17f2ac5e-637a-43d4-
a97b-2b1b8396be00:latest_draft/triggers/

--data '{

ERROR HANDLING

Replay any Event,
recover any workflow

Safely replay any workflow or steps to recover from failures without data loss. Deterministic replays ensure consistent, repeatable outcomes.

Build resilient pipelines
  1. 01 Choose what to replay: full workflow or only the failed steps.
  2. 02 Debug and Replay traffic at scale, even after downtimes.
  3. 03 Custom error handling and retry logic for complex enterprise requirements.
