MoEngage sends the campaign and user events you choose to a webhook. FlowMattic catches each one on your WordPress site and posts it to Slack, sorted by event, explained in plain words, or sent straight to the marketer who owns the campaign. For growth and CRM teams who run push, email and in-app campaigns in MoEngage.

1. TriggerSetup Webhook2. ActionSend Channel MessageWhen MoEngage fires Setup Webhook, FlowMattic runs Send Channel Message in Slack with the data from that event.
You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateEach event that reaches the webhook posts its name, campaign and user to the marketing channel, so the team sees a spike in clicks or conversions while the campaign is still live.

A Lookup Table matches the campaign name to its owner's email, Find User by Email finds them in Slack, and a direct message tells them what just happened in their campaign.

MoEngage payloads carry attribute names that only the CRM team knows. An AI Agent rewrites each event as one plain line before it reaches a channel that sales and support also read.

A Filter lets through only purchase events above the value you set, and Send Private Channel Message posts them where only the leadership group reads them.

At the end, each MoEngage event you send to the webhook posts a short message in the Slack channel you pick.
In FlowMattic, open Connects and add the Slack workspace your marketing team uses.
Create a workflow with MoEngage and Setup Webhook, then copy the URL FlowMattic shows on the trigger step.
In MoEngage, add the URL where your campaign or flow sends its webhook, then fire a test so FlowMattic captures the payload.
Add Slack Send Channel Message, choose the channel, map the event name, campaign and user fields, test the step and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
MoEngage and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Conversions, opt-outs and errors each land with the team that acts on them, instead of all of them waiting in a dashboard.
Event payloads with user attributes pass through your own WordPress site on the way to Slack, not through a third-party automation account.
Runs are unlimited on every FlowMattic plan, so a send to a million users that fires thousands of events needs no bigger plan.
Create a FlowMattic workflow with the MoEngage Setup Webhook trigger, add its URL to the webhook in your MoEngage campaign or flow, then add Slack Send Channel Message with the event fields mapped into the text.
Whatever MoEngage sends to the webhook URL. Point one or more campaigns or flows at it, then use a Router on the event name if each kind should go somewhere different.
Yes. Add a Filter after the trigger that passes only the event names or campaigns you care about. The rest end quietly without a message.
Yes. Keep a Lookup Table of campaign names and owner emails, use Find User by Email to get their Slack account and send the event with Send Direct Message.
Yes. Add a Google Sheets or WP Tables step to the same workflow before or after the Slack message, so the channel shows the alert and the table keeps the history.
