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#

New Direct Message (Instant) on Slack

Description:Emit new event when a message was posted in a direct message channel

Version:1.0.20

Key:slack-new-direct-message

View on GitHub

Slack Overview#

The Pipedream Slack app enables you to build event-driven workflows that interact with the Slack API. Once you authorize the Pipedream app's access to your workspace, you can use Pipedream workflows to perform common Slack actions or write your own code against the Slack API.

The Pipedream Slack app is not a typical app. You don't interact with it directly as a bot, and it doesn't add custom functionality to your workspace out of the box. It makes it easier to automate anything you'd typically use the Slack API for, using Pipedream workflows.

Automate posting updates to your team channels
Create a bot to answer common questions
Integrate with your existing tools and services
And much more!

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Slack	`slack`	`app`	This component uses the Slack app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`slackApphook`	`$.interface.apphook`
Ignore Bots	`ignoreBot`	`boolean`	Ignore messages from bots
Ignore Messages from Yourself	`ignoreSelf`	`boolean`	Ignores messages sent to yourself

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:

channels:historychannels:readchannels:writeemoji:readgroups:historygroups:readgroups:writeim:historyim:readim:writelinks:readlinks:writempim:historympim:readmpim:writereactions:readreactions:writereminders:readreminders:writestars:readteam:readusergroups:readusergroups:writeusers:readusers:read.emailusers:writechat:write:botchat:write:userfiles:write:usercommandsusers.profile:writeusers.profile:read

About Slack#

Slack is a channel-based messaging platform. With Slack, people can work together more effectively, connect all their software tools and services, and find the information they need to do their best work — all within a secure, enterprise-grade environment.

Action#

Generate PDF on HTML 2 PDF

Description:Creates a PDF from a URL or HTML string. [See the documentation](https://www.html2pdf.co.uk/api-documentation)

Version:0.0.1

Key:html_2_pdf-generate-pdf

View on GitHub

HTML 2 PDF Overview#

The HTML 2 PDF API allows you to convert HTML documents to PDFs. In Pipedream, you can integrate this API into workflows to automate document generation tasks. This can be incredibly useful for generating reports, invoices, or any other document where you start with HTML and need a PDF output. You can trigger these conversions with various events – like a new form submission, a scheduled trigger, or even updates in a database.
