Slack Get Messages

Retrieve messages from a Slack channel. In streaming mode, emits each message as a separate item.

Requires a Slack connection with channels:history (public) or groups:history (private) scope.

Configuration

Field	Description	Notes
Connection	Slack connection to use	Required
Channel	Channel name or ID	Required. Supports templates
Limit	Maximum number of messages	Default: 100, max: 1000
Oldest	Only messages after this Unix timestamp	Optional. Supports templates
Latest	Only messages before this Unix timestamp	Optional. Supports templates

Output

Returns an array of Slack message objects. Each message includes:

Field	Description
type	Always message
text	Message text content
user	User ID who sent the message
ts	Message timestamp (unique ID)
thread_ts	Thread parent timestamp (if in a thread)

Time Range Example

To get messages from the last 24 hours, use a Transform node to calculate the Unix timestamp and pass it via template:

Set Oldest to {{timestamp}} where timestamp is computed upstream.

TIP

Messages are returned in reverse chronological order (newest first). Use the Oldest and Latest fields to narrow the time range for large channels.
