New Message in Channel on Discord Bot

Description:Emit new event for each message posted to one or more channels

Version:0.0.12

Discord Bot Overview#

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

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
Discord Bot	`discord`	`app`	This component uses the Discord Bot app.
Guild	`guildId`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Channels	`channels`	`string[]`	Select a value from the drop down menu.
Emit messages as a single event	`emitEventsInBatch`	`boolean`	If `true`, all messages are emitted as an array, within a single Pipedream event. Defaults to `false`, emitting each Discord message as its own event in Pipedream
	`timer`	`$.interface.timer`

Trigger Authentication#

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

This app allows you to use the Discord API using your own Discord bot. If you don't want to use a custom bot, and you just need to use the Discord API, exit this screen and use the Discord app, instead.

If you want to use your own Discord bot, but haven't created one yet, see these instructions or watch this video. You'll need to add this bot to your server(s) to make successful API requests.

Once you've created your bot, you'll find the Bot token within the Bot section of your app. Enter that token below.

Upload String as File on SFTP (password-based auth)

Description:Uploads a UTF-8 string as a file on an SFTP server

Version:0.1.1

Key:sftp_password_based_auth-upload-file

View on GitHub

SFTP (password-based auth) Overview#

SFTP (Secure File Transfer Protocol) is a network protocol that provides secure
file transfers over secure shell (SSH) connections. It is an extension of the
Secure Shell protocol, designed for secure file exchange between hosts. A user
can securely transfer files between systems without having to worry about
external threats, as the protocol is encrypted and authenticated.

With the SFTP API, you can build applications that securely transfer data, such
as files and documents, between two different systems. Some example
applications include:

Secure document sharing between two systems
Secure file synchronization between two systems
Secure backups of data over the network
Secure transfers of large files
Secure uploads and downloads of data
Media streaming between two systems

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
SFTP (password-based auth)	`sftp_password_based_auth`	`app`	This component uses the SFTP (password-based auth) app.
data	`data`	`string`	A UTF-8 string to upload as a file on the remote server.
Remote Path	`remotePath`	`string`	The path to the remote file to be created on the server.

Action Authentication#

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

Below, enter the hostname of the SFTP server you'd like to connect to, your username, and the password you'd like to use to connect.

This app only supports password-based authentication, not authentication via private key. If you need to use a private key to connect to a host, please use the SFTP (key-based auth) app, instead.
