If you encountered unable to verify the first certificate as warning in Postman while hitting the API or getting response as "java.security.cert.CertPathValidationException: Trust anchor for certification path not found."
As a frontend developer, no need to worry about this as this issue is not from your side but to resolve this issue, you can ask your client to complete chain certificate and download all the certificates required.
To get more information about client certificate chain and what are the extra downloads required, test your client domain on

From this website, you'll get detailed information about SSL and certificates.
Thanks for reading this far, hope this will resolve your error.
Happy Coding!
