SSL certificate verification errors, like SSLCertVerificationError, can occur when making API calls in Python despite working in tools like Postman.
Python, especially with the requests library, enforces stricter SSL certificate validation compared to tools like Postman, leading to discrepancies.
Reasons for SSLCertVerificationError include differences in certificate verification settings, certificate chain issues, and misconfigured CA certificates between Python and Postman.
Solutions include temporarily bypassing SSL verification, updating CA certificates with certifi, or configuring custom CA certificates to address SSLCertVerificationError in Python.
