Capabilities and limitations

Learn about the capabilities and limitations of flows.

Topic	How it works
Copy & pasting	You can't copy and paste flow actions.
Maximum number of flow actions	Each flow can have up to 400 actions.
Test data	To use the variables generated at the trigger for the subsequent flow steps, you must first test the flow to ensure the payload populates correctly.
Test data and WhatsApp's customer care window	For WhatsApp, due to the 24-hour customer care window, you need data less than 24 hours old to test your flow. If you encounter issues while testing, re-populate the test data from the trigger.
Triggers	Each flow can be triggered by only one channel instance at a time.
