On January 21, 2019, we will be blocking all manual/custom integrations using the TLS 1.0 and 1.1 encryption protocols so that we can upgrade to only TLS 1.2 in order to apply the industry’s current best practice for security.
Please make sure your manual/custom integration with Pipedrive is updated to TLS 1.2.
If you have any questions about this change, please feel free to ask below.
