Details

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger

Description:Emit new events on new Slack [interactivity events](https://api.slack.com/interactivity) sourced from [Block Kit interactive elements](https://api.slack.com/interactivity/components), [Slash commands](https://api.slack.com/interactivity/slash-commands), or [Shortcuts](https://api.slack.com/interactivity/shortcuts).
Version:0.0.3
Key:slack-new-interaction-event-received

New Interaction Events Overview

Slack messages can contain interactive elements like buttons, dropdowns, radio buttons, and more. This source subscribes to interactive events, like when a button is clicked in a message.

Example of a Slack button

Then this source will be triggered when you or another Slack user in your workspace clicks a button, selects an option or fills out a form.

Example feed of interaction events coming from Slack

With this trigger, you can build workflows that perform some work with other APIs or services, and then reply back to the original message.

Trigger Authentication

Slack uses OAuth authentication. When you connect your Slack account, Pipedream will open a popup window where you can sign into Slack and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Slack API.

Pipedream requests the following authorization scopes when you connect your account:

Browserless Overview

Browserless allows you to build websites and applications that can be used
without a web browser. This means that you can create apps that can be used
offline, or that can be used on devices that don't have a web browser
installed.

Some examples of things that you can build using Browserless are:

  • A website that can be used without a web browser
  • An app that can be used offline
  • A app that can be used on devices that don't have a web browser installed
