Security and Authentication

To protect data from unauthorized access, QuickBooks data stores require connections to be authenticated with an access token or QuickBooks application information. Some data stores also require connections to be encrypted using the Secure Sockets Layer (SSL) protocol. The Simba QuickBooks ODBC Driver provides full support for these authentication protocols.

Note:

In this documentation, "SSL" refers to both TLS (Transport Layer Security) and SSL (Secure Sockets Layer). The connector supports up to TLS 1.2. The SSL version used for the connection is the highest version that is supported by both the connector and the server.

The connector uses the OAuth 2.0 protocol for authentication and authorization. You can authenticate your connection through OAuth 2.0 by specifying an access token, or by providing your QuickBooks application information so that the connector retrieves and uses the corresponding access token and refresh token. For detailed configuration instructions, see Configuring Authentication.

Additionally, the connector supports SSL connections with or without one-way authentication. If the server has an SSL-enabled socket, then you can configure the connector to connect to it.
