Sending Discord Messages, Embeds, and Webhooks in Studio

Studio gives you a full suite of blocks for sending, editing, and reacting to Discord messages — from a plain text message in a channel to a richly formatted embed with interactive buttons. This page covers every message and embed block available in the block editor, along with helper value blocks for colors, timestamps, and mentions.

Simple Messages

Use these blocks to send, edit, or delete text messages in Discord channels or via direct message.

Send Message

erlc_bot_send_message — Send a plain text message to a channel.

Input	Description
`CHANNEL_ID`	The target channel
`CONTENT`	The message text

Reply to Message

erlc_bot_reply_message — Reply to an existing message.

Input	Description
`MESSAGE_ID`	The message to reply to
`CHANNEL_ID`	The channel containing the message
`CONTENT`	The reply text

DM a User

erlc_bot_dm_user — Send a direct message to a server member.

Input	Description
`MEMBER_ID`	The recipient’s user ID
`CONTENT`	The message text

Edit Message

erlc_bot_edit_message — Edit an existing message sent by the bot.

Input	Description
`MESSAGE_ID`	The message to edit
`CHANNEL_ID`	The channel containing the message
`CONTENT`	The new message text

Deleting Messages

Delete Message

erlc_bot_delete_message — Delete a single message.

Input	Description
`MESSAGE_ID`	The message to delete
`CHANNEL_ID`	The channel containing the message

Bulk Delete Messages

erlc_bot_delete_messages — Delete multiple messages at once (up to Discord’s bulk-delete limit).

Input	Description
`CHANNEL_ID`	The channel to bulk-delete from
`AMOUNT`	Number of messages to delete

Publishing and Pinning

erlc_bot_publish_message — Cross-post a message from an announcement channel to all following channels. Inputs: MESSAGE_ID, CHANNEL_ID.
erlc_bot_pin_message — Pin or unpin a message. Inputs: MESSAGE_ID, CHANNEL_ID. Set the PINNED field to true to pin or false to unpin.

Fetching Messages

Use erlc_bot_fetch_message to retrieve a message and store its data for later blocks. Inputs: MESSAGE_ID, CHANNEL_ID. After fetching, read message properties with erlc_discord_bot_result_value by selecting a field from the dropdown:

Field	Description
`id`	The message’s snowflake ID
`channel_id`	The channel the message belongs to
`content`	The message text content
`author_id`	The Discord user ID of the author
`code`	HTTP response code
`url`	Jump URL to the message
`status`	Status string from the API response

Interaction Replies

When your automation is triggered by a slash command or button interaction, use these blocks to respond.

Interaction reply blocks only work inside a trigger that provides an interaction context, such as erlc_when_slash_command or erlc_when_discord_button. Using them outside of an interaction trigger will cause an error.

Block	Description
`erlc_bot_interaction_reply`	Send the initial reply to the interaction. Input: `CONTENT`
`erlc_bot_edit_interaction_response`	Edit the reply after it has been sent. Input: `CONTENT`
`erlc_bot_delete_interaction_response`	Delete the interaction reply entirely
`erlc_embed_send_hidden`	Send an ephemeral reply visible only to the user who triggered the interaction. Input: `BLOCKS` (statement)

Use erlc_embed_send_hidden to send private confirmation messages after a user clicks a button or submits a modal — other members won’t see the response.

Reactions

Add or remove emoji reactions on messages.

erlc_bot_add_reaction — Add an emoji reaction to a message.
- Inputs: EMOJI, MESSAGE_ID, CHANNEL_ID
erlc_bot_remove_reaction — Remove a specific user’s reaction from a message.
- Inputs: EMOJI, MEMBER_ID, MESSAGE_ID, CHANNEL_ID

For the EMOJI input, use the emoji’s Unicode character for standard emoji (e.g., 👍) or the custom emoji format <:name:id> for server emoji.

Webhooks

Send messages and embeds through a Discord webhook URL without requiring the bot to be in the channel.

erlc_discord_webhook — Send a plain text message via webhook.
- Inputs: URL (the webhook URL), CONTENT
erlc_embed_webhook — Send an embed via webhook. Connect embed component blocks to the BLOCKS statement input.
- Inputs: URL, BLOCKS (statement)
