Details

This integration uses pre-built, open source 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 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.
LabelPropTypeDescription

The query you'd like to run. See this AWS doc for help with query syntax

Emit query results as a single eventemitResultsInBatchboolean

If true, all events are emitted as an array, within a single Pipedream event. If false, each row of results is emitted as its own event. Defaults to true

timer$.interface.timer

Trigger Authentication

AWS uses API keys for authentication. When you connect your AWS account, Pipedream securely stores the keys so you can easily authenticate to AWS APIs in both code and no-code steps.

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Once done, enter your access and secret key below.

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.

LabelPropTypeDescription
SlackslackappThis component uses the Slack app.
ChannelconversationstringSelect a value from the drop down menu.
blocksblocksstring

Enter an array of structured blocks as a URL-encoded string. E.g., [{ "type": "section", "text": { "type": "mrkdwn", "text": "This is a mrkdwn section block :ghost: *this is bold*, and ~this is crossed out~, and <https://pipedream.com|this is a link>" }}]

Tip: Construct your blocks in a code step, return them as an array, and then pass the return value to this step.

Notification Texttextstring

Optionally provide a string for Slack to display as the new message notification (if you do not provide this, notification will be blank).

Send as Useras_userboolean

Optionally pass TRUE to post the message as the authed user, instead of as a bot. Defaults to FALSE.

Bot Usernameusernamestring

Optionally customize your bot's user name (default is Pipedream). Must be used in conjunction with as_user set to false, otherwise ignored.

Icon (emoji)icon_emojistring

Optionally provide an emoji to use as the icon for this message. E.g., :fire: Overrides icon_url. Must be used in conjunction with as_user set to false, otherwise ignored.

Icon (image URL)icon_urlstring

Optionally provide an image URL to use as the icon for this message. Must be used in conjunction with as_user set to false, otherwise ignored.

Action 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:
