Using API Token authentication

In order to use the integration with an API token you'll first need to change the Username / API Key (see '?') field to _api_token_key. Following this step, you can now enter the API Token into the Password field - this value will be used as an API key.

Using custom authentication header

In case the TAXII 2 server you're trying to connect to requires a custom authentication header, you'll first need to change the Username / API Key (see '?') field to _header: and the custom header name, e.g. _header:custom_auth. Following this step, you can now enter the custom auth header value into the Password field - this value will be used as a custom auth header.

Complex Observation Mode

Two or more Observation Expressions MAY be combined using a complex observation operator such as "AND", "OR", and "FOLLOWEDBY". e.g. [ IP = 'b' ] AND [ URL = 'd' ]. These relationships are not represented in in CORTEX XSOAR TIM indicators. You can opt to create them while ignoring these relations, or you can opt to ignore these expressions - if you chose the latter, then no indicator will be created for complex observations.
