FAQ

Slack connector FAQ

What can I sync with the Slack connector?

Slack's core objects — Channels, Messages, Threads, Users and custom fields — can sync with any of 194 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Slack?

Via Web API (HTTP RPC-style methods) plus the Events API, authenticated with OAuth 2.0 with bot or user tokens and granular scopes. Changes are detected as follows — events API webhooks, delivered over HTTP callbacks or Socket Mode. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Slack connector two-way?

Yes. Changes made in Slack propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a Slack integration take to set up?

Most Slack integrations go live in minutes: authenticate Slack and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Slack data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Slack data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
