# TSSslServerCertUpdate(3ts)

traffic Server TLS server cert update

## NAME

TSSslServerCertUpdate - traffic Server TLS server cert update

## SYNOPSIS

```
#include <ts/ts.h>
```

- ***TSReturnCode* TSSslServerCertUpdate(const char \*cert\_path, const char \*key\_path)**

  ## DESCRIPTION

*TSSslServerCertUpdate()* updates existing server certificates configured in *ssl\_multicert.config* based on the common name in *cert\_path*. if *key\_path* is set to nullptr, the function will use *cert\_path* for both certificate and private key. *TSSslServerCertUpdate()* returns *TS\_SUCCESS* only if there exists such a mapping, *cert\_path* is a valid cert, and the context is updated to use that cert.
