Transport Layer Security (TLS) is a cryptographic technology protocol used to provide secure transfer of sensitive information over the internet.
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. If you are using a Webhook to link Zoho to an external site, your browsers are required to support HTTPS and TLS v1.2.
Refer to this link for further details regarding the requirements.
If the response {"status": 200,"message": "Connection Success","version": "TLSv1.2"} is displayed, it means that you are connecting to our APIs using TLS 1.2.
