Flow Trigger

Upon the submission of the flow response from the user, business can make use of the Flow Trigger to send follow-up messages or perform other actions.

Selected Flow ID

If you would like to send a follow-up message when the user has submitted a flow, you can make use of the "Selected Flow ID to match the submission of the corresponding flow.

When "Match Selected Flow ID" is enabled, the "Flow Payload to Match" with be disabled.

Customized Matching Payload

When "Selected Flow ID" is enabled, you can also add a customized payload. As a result, only the flow containing the same Flow ID and Customized Matching Payload can be matched by the trigger.

Optionally, you can add the Customized Matching Payload in the "WhatsApp Flow" response.

The Customized Matching Payload is also supported in the "WhatsApp Flow template".

Flow Payload to Match

If you would like to send different follow-up messages depending on the answers submitted with the flow. You can specify the expected input in the "Flow Payload to Match".


When the "Flow Payload to Match" is applied, you need to specify at least one input for matching.

Expected Outcome

User inputs the expected answer and submit.
