Mutual TLS type


Mutual TLS (also known as MTLSmutual SSLmutual authentication, or two-way authentication) is a requirement of certain endpoints, where the server requires verification of the client’s identity.

Tines’ HTTP Request Action supports mutual TLS through the mutual_tls configuration option. This is most easily used alongside a special mutual TLS credential type.

Creating a mutual TLS credential 

Enter the following information in the New Credential page, after selecting mutual TLS from the dropdown:

  • Root certificate: The root certificate file for the certificate authority (CA) responsible for signatures

  • Client certificate: The certificate file issued by the CA for this client

  • Client private key: The private key file for the client certificate

These files will often have the extension .pem or .crt, but any plain text file will be accepted.

Using a mutual TLS credential with a HTTP Request Action 

Include a CREDENTIAL formula expression in the action's mutual_tls configuration option.


For a mutual TLS credential named "mtls_example":

  "url": "https://internal.tool",
  "method": "get",
  "content_type": "json",
  "mutual_tls": "<<CREDENTIAL.mtls_example>>"
