Slack connector details
The Slack capture connector in Estuary captures workspace data from Slack through its APIs and loads each selected resource into an Estuary collection. It supports conversations, messages, users, files, threads, and related workspace data for downstream analytics, search, archiving, and other data workflows.
- API-based data capture from Slack
- Supports Channels (Conversations) and Channel Members
- Captures Messages and Threads
- Supports Users and User Groups
- Captures Files and Remote Files
- Separate Estuary collections for each selected Slack resource
- Configurable start date to determine how far back Slack data is replicated
- Configurable thread lookback window for retrieving historical thread messages
- Option to automatically join available channels
- Slack workspace or API-token authentication, with OAuth supported in connector configuration
The start date determines the earliest Slack data Estuary will replicate, while the thread lookback window controls how far back the connector searches for messages in conversation threads. Each enabled Slack resource is mapped to a separate Estuary collection by default.

HIGH THROUGHPUT
Distributed, event-driven architecture scales for demanding data workloads.
DURABLE COLLECTIONS
Store data as it moves so you can transform, replay, and deliver it downstream.
FLEXIBLE LATENCY
From <100ms CDC and real-time streaming to scheduled batch, depending on connector capabilities.
From <100ms to batch
Estuary supports CDC, real-time streaming, incremental syncs, and scheduled batch across its connector ecosystem. Capture data from Slack using the cadence supported by the connector, then transform and deliver it to the destinations your team uses.
- Connect Slack to warehouses, databases, data lakes, search platforms, and event systems through Estuary-supported destinations.
- Capture once and reuse Slack data across transformations and multiple downstream destinations without rebuilding source extraction.
