Trello Overview#

Trello's API lets you craft workflows around managing boards, lists, cards, and users. With Pipedream, you can automate Trello tasks, like syncing cards with external databases, updating checklists, and posting notifications to other platforms. It enables seamless connection with other apps, fostering productivity by automating routine board operations, card management, and team notifications.

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
Trello	`app`	`app`	This component uses the Trello app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
Board	`board`	`string`	Select a value from the drop down menu.
Lists	`lists`	`string[]`	Select a value from the drop down menu.

Trigger Authentication#

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

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

Send Message (Advanced) on Slack

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!

Action Configuration#

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

Label	Prop	Type	Description
Slack	`slack`	`app`	This component uses the Slack app.
Channel	`conversation`	`string`	Select a value from the drop down menu.
Text	`text`	`string`	If you're using `blocks`, this is used as a fallback string to display in notifications. If you aren't, this is the main body text of the message. It can be formatted as plain text, or with mrkdwn.
Send text as Slack mrkdwn	`mrkdwn`	`boolean`	`TRUE` by default. Pass `FALSE` to disable Slack markup parsing. See docs here
Attachments	`attachments`	`string`	A JSON-based array of structured attachments, presented as a URL-encoded string (e.g., `[{"pretext": "pre-hello", "text": "text-world"}]`).
Parse	`parse`	`string`	Change how messages are treated. Defaults to none. By default, URLs will be hyperlinked. Set `parse` to `none` to remove the hyperlinks. The behavior of `parse` is different for text formatted with `mrkdwn`. By default, or when `parse` is set to `none`, `mrkdwn` formatting is implemented. To ignore `mrkdwn` formatting, set `parse` to full.
Link Names	`link_names`	`boolean`	Find and link channel names and usernames.
Send as User	`as_user`	`boolean`	Optionally pass `TRUE` to post the message as the authenticated user, instead of as a bot. Defaults to `FALSE`.
Schedule message	`post_at`	`string`	Messages can only be scheduled up to 120 days in advance, and cannot be scheduled for the past. The datetime should be in ISO 8601 format. (Example: `2014-01-01T00:00:00Z`)
Include link to workflow	`include_sent_via_pipedream_flag`	`boolean`	Defaults to `true`, includes a link to the workflow at the end of your Slack message.
Customize Bot Settings	`customizeBotSettings`	`boolean`	Customize the username and/or icon of the Bot
Reply to Thread	`replyToThread`	`boolean`	Reply to an existing thread
Add Message Metadata	`addMessageMetadata`	`boolean`	Set the metadata event type and payload
Configure Unfurl Settings	`configureUnfurlSettings`	`boolean`	Configure settings for unfurling links and media
Add Blocks - Reference Existing Blocks Array or Configure Manually?	`passArrayOrConfigure`	`string`	Select a value from the drop down menu:`{ "label": "Reference an array of blocks", "value": "array" }{ "label": "Configure blocks individually (maximum 5 blocks)", "value": "configure" }`
