**Note: **
Eligibility depends not only on business verification, but also on WABA quality and messaging limits. To determine if a client is eligible to use Flows, you should attempt to send a Flow. If the account is not yet eligible, Meta recommends focusing on improving the quality of the current WABA (WhatsApp Business Account).
Once the quality checks are successfully completed, your account will receive higher messaging limits and access to Flows.

After you create a WhatsApp Flow, you can send it. To send a message with a flow, we have introduced a new type of the Interactive Object called flow.
