The member registration confirmation e-mails are not being sent out. How do I set it up?

To send out registration confirmation e-mails, "send_email_flg" needs to be enabled on the member registration endpoint. Go to the API module in the admin panel and verify your settings for the corresponding endpoint.

Enabling "send_email_flg"

In the left sidebar menu, click [API] and select the target API from the expanded list.

Under "Member", click [Update] next to the endpoint with "insert" as the operation type.

Verify that "send_email_flg" under "Advanced settings" is selected.

Click [Update] at the bottom of the screen to apply these settings.
