This documentation is for frevvo v10.0. Not for you? Earlier documentation is available too.



frevvo was designed to integrate with your back end systems. The form server is built using industry standard such as XSD, XML and Restlet. This chapter covers the built-in connectors as well as how to add your own connectors to the form server.

  • frevvo Connectors are an Add on feature with additional costs.
  • frevvo only supports/certifies frevvo connectors running in the Apache Tomcat container. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified by frevvo.

Integrating Connectors with frevvo Cloud Server

Connectors are most commonly installed behind your firewall where they can access (connect) to your back end systems in order to read/write data. If you use the frevvo Cloud hosted server you must ensure that your Connectors are accessible from our servers. This is done by opening up one of the following ports on your firewall:

We recommend that you use https and not http. Https is a secure channel.

  • HTTP Ports: 80, 8082 or 19080
  • HTTPs Ports: 443, 8443 or 19443

For customers that use firewall white-listing, also make sure the frevvo cloud outgoing server IP Addresses and (host are added to the list.


Database Connector

The Database Connector makes it very easy to connect frevvo to most databases. You can save form submissions in your database or initialize forms from a database. Note that this connector uses XML schema.

See Database Connector for help installing and using this connector.

Filesystem Connector

The Filesystem Connector saves frevvo submissions to a local or remote filesystem or an Enterprise Content Management system (ECM). See Filesystem Connector for easy installation and configuration information.   

Google Connector

Connecting your frevvo to Google sheets and drive is very easy to do with the frevvo Google Connector. See the Google Connector chapter for help installing and using this connector.

SharePoint Connector

Store documents and information to a secure Microsoft SharePoint website. Configure the frevvo SharePoint Connector for your frevvo tenant then use the SharePoint wizard to connect your forms/workflows to the SharePoint website for document storage. . Refer to the SharePoint Connector topic for the details. 

Connector Security

frevvo connectors installed on-premise should only be accessible to the frevvo server and should not be remotely accessible. frevvo recommends only allowing HTTPS access to the server (not external HTTP access). Since the connector(s) is not exposed over HTTPS, remote code execution vulnerability can be mitigated (a remote attacker cannot exploit this vulnerability as it is not exposed). 

If you choose to allow external access to HTTP, you should only allow requests with paths starting with /frevvo for port 8082 (or the port you are using for frevvo and the Connector(s)). 

See also Database Connector Security.

Confluence Add-on

The frevvo Add-on for Confluence is available as an add-on to either frevvo' Online service or In-house installations. You need to install it into Confluence before you can add forms and submissions pages to Confluence. You will also need to download and install frevvo for Confluence.

See frevvo ™ for Confluence documentation for help installing and using this plugin.
