If you're listed as an Approver in the Approval Policy, Airbase will notify you on Slack when a User requests for a Virtual Card expense.
You can choose to Approve, Deny, Ask a question, or Add a new Approver.
The notification also includes a link that will redirect you to the request on Airbase. The Approver can check other information, such as GL categorization on the request page if needed.
The option you choose on Slack will reflect on the Virtual Card in Airbase.
The requester will receive a notification on their Slack.
