Event Streams — Large Payload Support

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.
