# Inforiver Writeback Matrix prerequisites

To set up Inforiver Writeback Matrix, two additional steps must be completed in collaboration with the Power BI administrator.

* Since Inforiver is an add-on visual that operates on top of the Power BI framework, users must log in with their Microsoft O365 account. [Admin consent](https://docs.inforiver.com/introduction-to-inforiver/get-started/inforiver-writeback-matrix-prerequisites/admin-consent-for-inforivers-entra-id) will be required to log in, add writeback destinations, or connect to integrations like Teams or SharePoint.
* Network firewalls block connections from IP addresses that do not have permission. [Whitelist Inforiver’s outbound IPs in your Azure SQL database firewall rules.](https://docs.inforiver.com/introduction-to-inforiver/get-started/inforiver-writeback-matrix-prerequisites/whitelist-inforiver-ips)
