The new Slack platform and the features described below are in beta and under active development.

Event Triggers

Invoke a workflow when a specific event happens in Slack

Event triggers are another type of automatic trigger, in that they don't require manual activation. They won't be triggered on their own, however. Instead, they're automatically triggered when a certain event happens.

Supported events

Your app needs to have the proper scopes to use event triggers. Include these scopes within your app's manifest.

Supported Event Description Required Scopes
app_mentioned Subscribe to only the message events that mention your app or bot app_mentions:read
channel_archived A channel was archived channels:read
channel_created A channel was created channels:read

We'll continue to add more triggerable events in the future. Stay tuned!

Avoid infinite loops

Your app can respond to events and be the cause of events. This can create situations where your app gets stuck in a loop.

For example, if your app listens for all message_posted events in a channel and then posts its own message in response, it'll keep posting messages forever! That's why the message_posted event requires a filter.

Carefully construct a filter to prevent boundless behavior. If your app does get stuck in an infinite loop, you can delete the trigger and the behavior will cease.

Create an event trigger

Triggers can be added to workflows in two ways:

  • You can add triggers with the CLI. These static triggers are created only once. You create them with the Slack CLI, attach them to your app's workflow, and that's that. The trigger is defined within a trigger file.

  • You can add triggers at runtime. These dynamic triggers are created at any step of a workflow so they can incorporate data acquired from other workflow steps. The trigger is defined within a function file.

Create an event trigger with the CLI

Slack CLI built-in documentation
Use slack trigger --help to easily access information on the trigger command's flags and subcommands.

Before you can create a trigger with the CLI, you'll need to be running your app locally in a development environment (with the slack run command) or have deployed your app in production (with the slack deploy command).

The triggers you create when running locally will not work when you deploy your app in production. You'll need to create any triggers again with the CLI.

Create the trigger file

To create an event trigger with the CLI, you'll need to create a trigger file. The trigger file contains the payload you used to define your trigger.

Create a TypeScript trigger file within your app's folder with the following form:

import { Trigger} from “deno-slack-api/types.ts”;

const trigger : Trigger<typeof ExampleWorkflow.definition> = {
  // your TypeScript payload
}

export default trigger;

Your TypeScript payload consists of the parameters needed for your own use case. The following is a TypeScript payload for creating an event trigger that listens for a reaction_added event in a specific channel:

  type: "event",
  name: "Reactji response",
  description: "responds to a specific reactji",
  workflow: "#/workflows/myWorkflow",
  event: {
    event_type: "slack#/events/reaction_added",
    channel_ids: ["C123ABC456"],
    filter: {
      version: 1,
      root: {
        statement: "{{data.reaction}} == sunglasses"
      }
    }
  },
  inputs: {
    stringtoSend: {
      value: "how cool is that",
    },
    channel: {
      value: "C123ABC456",
    },
  }

Once you have created a trigger file, use the following command to create the event trigger:

slack trigger create --trigger-def "path/to/trigger.ts"

Create an event trigger at runtime

The logic of a runtime trigger lies within a function's TypeScript code. Within your functions folder, you'll have the functions that are the steps making up your workflow. Within this folder is where you can create a trigger within the relevant <function>.ts file.

When you create a runtime trigger, you can leverage inputs acquired from functions within the workflow. Provide the workflow definition to get additional typing for the workflow and inputs fields.

Create an event trigger at runtime using the client.workflows.triggers.create method within the relevant function file.

const triggerResponse = await client.workflows.triggers.create<typeof ExampleWorkflow.definition>({
  // your TypeScript payload
});

Your TypeScript payload consists of the parameters needed for your own use case. Below is a function file with an example TypeScript payload for an event trigger. This specific TypeScript payload is for creating an event trigger that listens for a reaction_added event in a specific channel:

// functions/example_function.ts
import { DefineFunction, Schema, SlackFunction } from "deno-slack-sdk/mod.ts";
import { SlackAPI } from "deno-slack-api/mod.ts"; 

export const ExampleFunctionDefinition = DefineFunction({
  callback_id: "example_function_def",
  title: "Example function",
  source_file: "functions/example_function.ts",
});

export default SlackFunction(
  ExampleFunctionDefinition,
  ({ inputs, client }) => {

  const triggerResponse = await client.workflows.triggers.create<typeof ExampleWorkflow.definition>({
    type: "event",
    name: "Reactji response",
    description: "responds to a specific reactji",
    workflow: "#/workflows/myWorkflow",
    event: {
      event_type: "slack#/events/reaction_added",
      channel_ids: ["C123ABC456"],
      filter: {
        version: 1,
        root: {
          statement: "{{data.reaction}} == sunglasses"
        }
      }
    },
    inputs: {
      stringtoSend: {
        value: "how cool is that",
      },
      channel: {
        value: "C123ABC456",
      },
    }
  });

  // ...

Trigger filters

Trigger filters allow you to define a set of conditions for a trigger which must be true in order for the trigger to trip. For example, you might want to have a reaction_added trigger that only triggers if the reaction was a :eyes: reaction, and not on any other reaction.

You can use filters to prevent your app from responding to events it causes, which would potentially cause an infinite loop of responses.

Trigger filters are implemented by inserting a filter payload within your trigger object. The payload takes the form of an object containing blocks of conditional logic.

The logical condition within each block can be one of two types:

  • Conditional expressions (e.g. x < y)
  • Boolean logic (e.g. x AND y)

Conditional expression blocks need a single statement key with a string containing the comparison block. Values from the inputs payload can be referenced within the comparison block:

    filter: {
      version: 1,
      root: {
        statement: "{{data.reaction}} == sunglasses"
      }
    }

Boolean logic blocks are made up of two key:value pairs:

  • An operator key with a string containing the comparison operator
  • An inputs key with the child blocks

The child blocks then contain additional logic. In this case, it's two conditional expression blocks:

    filter: {
      version: 1,
      root: {
        operator: "OR"
        inputs: [{
          statement: "{{data.reaction}} == sunglasses"
        },
        {
          statement: "{{data.metadata.event_payload.incident_type}} == 'security'"
        }],
      }
    }

Nested logic blocks
You can use the same boolean logic to create nested boolean logic blocks. It's boolean logic all the way down - up to a maximum of 5 nested blocks, that is.

With your desired filter designed, set it within your trigger object.

Event trigger response

The response will have a property called ok. If true, then the trigger was created, and the trigger property will be populated.

Your response will include a trigger.id; be sure to store it! You use that to update or delete the trigger if need be. Perhaps consider storing it in a Datastore.

Manage an event trigger

A newly created trigger will only be accessible to others inside a workspace once its creator has granted access using the access Slack CLI command.

Grant access

Required Flag Description Example Argument
--trigger-id Provide the trigger_id as the argument Ft123ABC
--grant A switch to grant access

Set one of the following flags to grant access to different groups of people.

Flag Description Example Argument
--users Provide the user_id of desired users as the argument U123ABC U456DEF
--app-collaborators A switch to control access of all app collaborators
--everyone A switch to control access of all workspace members

The following example command grants access to the trigger FtABC123 for users U123ABC and U456DEF.

slack trigger access --trigger-id FtABC123 --users U123ABC U456DEF --grant

Revoke access

Flag Description Example Argument
--trigger-id Provide the trigger_id as the argument Ft123ABC
--users Provide the user_id of desired users as the argument U123ABC U456DEF
--revoke A switch to revoke access

The following example command revokes access to the trigger FtABC123 for users U123ABC and U456DEF.

slack trigger access --trigger-id FtABC123 --users U123ABC U456DEF --revoke

Update an event trigger

Update a trigger with the CLI

Make an update to a pre-existing trigger with the CLI by using the slack trigger update command. Provide the same payload you used to create the trigger in its entirety, in addition to the trigger ID.

slack trigger update --trigger-id Ft123ABC --trigger-def "path/to/trigger.ts"

Update a trigger at runtime

You can update a runtime trigger, but the trigger must be updated in its entirety. Use the same structure as client.workflows.triggers.create() but for client.workflows.triggers.update with the additional trigger_id parameter.

client.workflows.triggers.update<typeof ExampleWorkflow.definition>({
  trigger_id: "FtABC123",
  type: "<specific-trigger-type>",
  name: "My trigger",
  workflow: "#/workflows/myworkflow",
  inputs: {
    input_name: {
      value: "value",
    }
  }
});

Delete an event trigger

Delete a trigger with the CLI

You can delete a trigger with the slack trigger delete command.

slack trigger delete --trigger-id FtABC123

Delete a trigger at runtime

Deleting a runtime trigger deletes that specific trigger created in one instance of the Workflow. This means that you'll need to have stored the trigger_id created for that instance. Your app will continue to be able to create triggers until you remove the relevant code.

You can delete a runtime trigger by using client.workflows.triggers.delete().

client.workflows.triggers.delete({
   trigger_id: "FtABC123"
});
