Implementing Slack reactions

This page describes how to implement Slack actions in Serialized.

The action type (SLACK_POST) requires the field targetUri to be populated with a valid Slack webhook URI. The message text is specified in the field body. Simple templating is supported and event data can be accessed using dot (.) notation.

Example of a Reaction posting a notification to Slack:

{  "reactionName": "on-order-placed-slack-notifier",  "feedName": "order",  "reactOnEventType": "OrderPlacedEvent",  "action": {    "actionType": "SLACK_POST",    "targetUri": "https://hooks.slack.com/services/T0000/B0000/XXXX",    "body": "A new order with number ${event.data.orderNumber} was placed by ${event.data.customer.email}!"  }}

Given this event:

{  "eventId": "ca37d05c-a852-4de5-961f-16fb35e8cd7b",  "eventType": "OrderPlacedEvent",  "data": {    "orderNumber": "12312345",    "customer": {      "email": "customer@example.com"    }  }}

the message to Slack will look like this:

A new order with number 12312345 was placed by customer@example.com!
