Table of Contents
During flow execution, API calls from internal modules could exceed rate limits, causing intermittent failures. There was no mechanism within Programmable Flow to define or enforce rate limiting at the flow action level.
This feature introduces a dedicated Rate Limit management tab and a new Apply Rate Limit flow action, aligning Programmable Flow with downstream throttling controls across other modules.
Rate Limit Tab
A new Rate limit tab is available for creating and managing global rate limit definitions used across flows.
Setting Up a Rate Limit Definition
- Navigate to Developer Hub → Rate limit tab.
- Click Create and fill in:
- Name (maximum 100 characters).
- Rate number (1–200 per minute).
- Click Save. The new rate limit appears in the table with its UUID, name, and rate value.
- To modify an existing entry, click Edit and confirm the warning prompt.
- To remove an entry, click Delete. Only rate limits not currently assigned to any flow can be deleted.
Additional behaviors:
- Edit — Allows updating the name and rate number
- Delete — Rate limits that are actively in use cannot be deleted
Apply Rate Limit Action
A new flow action named Apply rate limit is available under the Utility category when building flows.
- Open or create a flow in Developer Hub → Programmable Flow.
- Add a new action and select Utility → Apply rate limit.
- In the action configuration, use the dropdown to:
- Select an existing rate limit, or
- Create a new rate limit directly from the dropdown.
- Save the flow.
