Trigger#

New Currency Fluctuation on Open Exchange Rates

Description:Emit new event when a new significant change in a specified currency rate is detected.

Version:0.0.1

Open Exchange Rates Overview#

The Open Exchange Rates API provides real-time and historical exchange rates for currencies worldwide, which enables you to retrieve the latest currency data for any purpose like financial reporting, pricing products in multiple currencies, or converting currency for international transactions. In Pipedream, you can tap into this API to create workflows that automate currency-related tasks, enrich data with current exchange rates, and trigger actions based on currency fluctuations.

Label	Prop	Type	Description
Open Exchange Rates	`app`	`app`	This component uses the Open Exchange Rates app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling interval	`timer`	`$.interface.timer`	Pipedream will poll the Open Exchange Rates on this schedule
Currency Id	`symbol`	`string`	Select a value from the drop down menu.
Change	`change`	`string`	The change you consider significant.

Build and Send a Block Kit Message 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 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:

bookmarks:writecalls:readcalls:writechannels:historychannels:readchannels:writednd:readdnd:writeemoji:readfiles:readgroups:historygroups:readgroups:writeim:historyim:readim:writelinks:readlinks:writempim:historympim:readmpim:writepins:readpins:writereactions:readreactions:writereminders:readreminders:writeremote_files:readremote_files:sharestars:readstars:writeteam:readusergroups:readusergroups:writeusers:readusers:read.emailusers:writechat:write:botchat:write:usercommandsfiles:write:userusers.profile:writeusers.profile:readsearch:read
