Changelog

Event Streams message size limits are raised from 512KB (recipe) / 1MB (API) to 10MB — large JSON payloads publish natively, no splitting or trimming required.

• 10MB Max Message Size — Publish large payloads directly across both connector actions/triggers and public APIs, with consistent behavior no matter how you publish.
• Dynamic Batching in recipes — Batches are capped at 50MB total payload; when messages approach the 10MB limit, Workato automatically returns remaining messages in subsequent batches with no data loss.

Event topics can be shared across workspaces within the same Automation HQ, so recipes across multiple workspaces work off the same shared topic in real time — no workarounds, no duplicated topics.

• One Org-Wide Switch — An AHQ admin enables cross-workspace sharing once; any managed workspace can then grant topic access to any other.
• Workspace-Managed Grants — Workspace admins select which topics to share and assign Publish, Subscribe, or both permissions per workspace.
• Multiple Publishers & Subscribers — Several workspaces can publish to and consume from one shared topic simultaneously.
• Clear Topic Differentiation — Shared topics carry a Granted tag so it's immediately clear which topics were shared versus owned, visible in both the topic list and the recipe's Message Topic dropdown.
• Schema & Message History Access — All granted workspaces can view the schema and full message history of any topic shared with them.

Recipe Lifecycle Management exports involving Workato Event streams will now include retention period configurations in exports. This will help ensure consistent behavior when migrating topics.

Workato Pub/Sub has been rebranded to Event Streams to reflect the product capability more accurately. Here's how the rebranding will affect users:

1. Workato PubSub is now Workato Event Streams
2. PubSub topics are now referred to as Event topics
3. In Workato’s documentation, Event Streams have been moved from the connectors section to a dedicated Event Streams section.

First, the new batch publish action allows you to send a batch of up to 100 events to a PubSub topic within one action. It's a valuable addition the Workato PubSub connector to go alongside the existing batch trigger.

Second, the PubSub API was moved to a totally new microservice resulting in increased throughput and up to a 50% latency decrease. The new API is now available on a new domain, event-streams.workato.com. Note that the old API version is still in operation and that both versions share the same auth tokens, data format, and endpoints to make it simple to migrate to the new API.

For instances that need a higher payload capacity, the message size for Workato Event Stream events has been increased to 512KB.

The new Workato Event Stream (PubSub) admin UI comes with an activity log for greater visibility—as well as the ability to preview messages,  change topics' retention period and reset (purge) topics.
