And since TLS is dependent on Secure Sockets Layer (SSL) certificates to encrypt traffic, developers need solutions for yet another layer of potential friction. Encryption is pushing API providers to leverage Transport Layer Security (TLS) to secure the data, content, and other resources that are being passed back and forth during each API request and response. Just like when it comes to making API requests and working with responses, Postman aims to give you greater control when it comes to configuring API encryption-which is now a standard part of API operations in 2020.
