Why teams connect Braze and Slack

Stop re-entering the same information in Braze and Slack: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Subscription Groups, Content Blocks, Users, Custom Attributes in Braze with Threads, Users, User groups, Files in Slack in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • Keep subscription and consent states consistent between Braze subscription groups and the CRM or CDP of record.
  • Export campaign and Canvas engagement data into a warehouse for cross-channel reporting.
  • Sync the Slack user directory with the HRIS or identity provider to keep memberships and profiles current
  • Archive channel messages into a warehouse or database for compliance and analytics

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between Braze and Slack

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Braze objects Slack objects
Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization. Users Workspace members with profile fields, synced against HR systems and identity providers.
Custom Events Behavioral events pushed into Braze to trigger campaigns and Canvases. User groups Handles like @support that map to teams in external systems.
Purchases Transaction records logged against profiles for revenue-based targeting. Files Uploads attached to messages, retrievable for archiving.
Segments Audience definitions read for membership export and campaign targeting. Reactions Emoji responses that can drive workflows, such as approving a synced record.
Campaigns Message sends whose metadata and analytics are read for reporting. Channels Conversations (public, private, DMs) that messages are read from and posted to.
Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods.
