Intuit requires upgrading to TLS 1.2 to align with industry best practices for security and data integrity.

On July 31, 2017, Intuit disabled the TLS 1.0 and TLS 1.1 encryption protocol, preventing apps still using them from accessing Intuit and QuickBooks APIs and Services.

Additionally, Intuit requires an upgrade to TLS 1.2 by December 31, 2017. On December 31, 2017, Intuit will disable the TLS 1.1 encryption protocol.

Refer: Intuit's News:

TLS 1.0 and 1.1 Disablement for the Intuit Developer Group


Upgrading your apps to support TLS 1.2

The current version of the .NET SDK (v3.2.1) uses .NET Framework 4.0. We are migrating the .NET SDK (.NET SDK for QuickBooks Online V3.2.1) to Framework 4.6.1 to support TLS 1.2 proactively.

Update from Intuit (Dec 21, 2017) - "Based on developer feedback, we are extending the deadline to March 31, 2018." 

Update from Intuit (March 31, 2018) - "Based on developer feedback, we are extending the deadline to September 20, 2018." 


Intuit QuickBooks Online .NET SDK uses .Net Framework 4.6.1 or above.

QODBC Online  to uses .Net Framework 4.6.1

QODBC Online or later uses .Net Framework 4.7.2


What do you need to do?:

After September 20, 2018, You may not be able to connect to QuickBooks Online using QODBC Online's old version.
