In order to maintain your communication with Zoho Books more secure and to meet the updated PCI standards, we will be retiring the support for TLS versions 1.0 and 1.1 on March 31, 2018. After this date, users will be required to update their processing solutions to TLS v1.2 in order to enjoy secure transfer of data. 

What is TLS?

Transport Layer Security (TLS) is a cryptographic technology protocol used to provide secure transfer of sensitive information over the internet.

Why is this update necessary?

According to PCI standards, TLS v1.2 is the most advanced protocol yet as it eliminates the vulnerabilities faced by the previous versions, i.e, TLS v1.0 and v1.1. All users who use secure servers and browsers to access the data and API from Zoho are expected to make this update to enjoy a seamless flow of secured data. If you are using a Webhook to link an external site, you are required to support HTTPS and TLS v1.2 in order to receive webhooks from Zoho.
