Outbound TLS rule

This rule uses TLS certificates to verify outbound endpoints during API processing.

Verifies TLS certificates for outbound requests to external endpoints. When a Snaplex receives a request for an external endpoint and this rule is configured, the Snaplex connects to the external resource as a client and verifies the server TLS certificate. After verification, the Snaplex continues with the request to the external endpoint.

Rule execution order

This rule executes before the other rules.

Field/Field set Description
When this rule should be applied An expression that defines one or more conditions that must be true for the rule to execute.

Example: The expression request.method == "POST" causes the rule to execute only on POST requests.

Certificate Input Format Required.Select the method for certificate: The available options are:
  • RAW_TEXT: Opens text field for key files where you can paste the keys.
  • FILE_PATH: Enables filepath selector as you type the path:
    1. Click to preview the file in Manager.
    2. Click to select a file:
    • Under the Project, pick the target file from Manager.

When the certificate is input, the Preview Type contains the following options:

  • Hex: Displays the preview data in hexadecimal format.

  • Text: Displays the preview data in text format.
