Zoho invoice/Slack integration not showing all payments

Zoho invoice/Slack integration not showing all payments

We successfully set up our Zoho invoice account with Slack to easily show payments received. And it works just fine for any online payments that come through.

However, any payments that are manually put in, don't show a notification in the slack thread. So if we receive a check, for example, and one of us manually puts in the customer payment for their account, it does not send a notification to slack.

Please let me know if I have missed something in the settings somewhere. Thank you,
