Steps to send messages until there is a response from the client

Create an SMS flow

Add the ‘Wait For SMS Reply’ step.

Please, drag the Wait For SMS Reply step and you will have this step under the login section.

On the settings page, you can set the time that how long you want to wait for the reply.

And create at least on response lookup condition

Now, we have three branches

Timeout: If there is no reply within the specified time

No Match: It means, the user replied, but the response lookup condition didn’t match

Lookup Condition 1: It means the user replied, and the response lookup condition also matched

As per our requirement, repeat the ‘Send SMS’ and ‘Wait for SMS Reply’ steps
