Summary
New configuration limits are being applied to Process Automation Triggers to ensure data remains within supported database constraints. The following limits will now be enforced:
- Trigger “name”: maximum length of 162 characters
- “jsonPath” in match criteria: maximum length of 500 characters
- “value” in match criteria: maximum length of 512 characters
- “values” list: maximum of 740 entries
- Length of each entry in “values” list: maximum of 2440 characters
Exceeding any of these limits will result in a 400 Bad Input response when using the Create or Update endpoints.
Effective Date
Monday, December 8, 2025
Details
These limits are being introduced to prevent configurations from exceeding the maximum size supported by DynamoDB, the underlying data storage system.
Customer Impact
This change will have no impact on existing triggers. It will only affect attempts to create or update triggers with configurations that exceed the new limits.
All limits have been set above currently observed customer usage patterns.
