Why integrate Relay with Slack

The Relay to Slack integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.

Break sprawling automations into manageable pieces

Relay lets one workflow hand off to another, so each piece stays focused and easy to maintain. Update or reuse a single step without touching everything downstream.

Catch workflow failures before they cost you an order

When a workflow errors, Relay routes the failure to another workflow that retries the task, alerts your team, or reroutes the order. Nothing silently drops.

Let AI decide how to handle a broken workflow

Your AI assistant reviews the failed step, the data involved, and past outcomes, then chooses whether to retry, escalate, or reroute the task. No manual triage required.

Alert your team the moment stock runs low

MESA watches inventory levels across your catalog and sends a Slack message the instant a threshold is hit. Your team can act before customers ever see a stockout.

Keep your team in the loop on every order

When an order comes in with specific conditions — high value, wholesale, flagged address — MESA sends a Slack alert instantly. No one has to check dashboards to know what needs attention.

Replace manual status updates with automatic ones

When a fulfillment status changes in Shopify, MESA posts the update to the right Slack channel. Your ops team always knows where orders stand without chasing tracking numbers.

Build any Relay and Slack automation

MESA helps you connect apps to automate repetitive tasks. A trigger is an event that starts a workflow, and actions are the steps that occur when it's running.
