Add custom fields to your playbook

You can define and use your own custom fields for events — either globally or for specific event types — in a playbook. For example, you might add a custom field named Department and assign it a list of values for each department in your organization (for example, IT Ops, Sales, and Business).

Using custom fields in playbooks requires special coding.

Plan your naming convention carefully. Custom field names described here require additional special handling:

• names containing characters other than letters, numbers, or underscores (_)
• names starting with a space

Update and read custom field values

To update custom field values in containers, use the following code examples with the container.update API :

Update a custom field value

Example code to update a custom field value from a container.

    outputs = {}
    
    # Write your custom code here...
    container = {"id": container_id}
    update = {
        "custom_fields": {
            field_name: field_value,
        },
    }

    # Make the HTTP request
    success, message = phantom.update(container, update)
    
    assert success, message
    
    # Return a JSON-serializable object
    assert json.dumps(outputs)  # Will raise an exception if the :outputs: object is not JSON-serializable
    return outputs

Read a custom field value

While not technically an update function, reading a custom field value also uses the container.update API.

Example code to read (get) a custom field value from a container.

   outputs = {}
    
    # Write your custom code here...
    container = phantom.get_container(container_id)
    custom_fields = container.get("custom_fields", {})
    outputs["field_found"] = field_name in custom_fields
    outputs["field_value"] = custom_fields.get(field_name)
    
    # Return a JSON-serializable object
    assert json.dumps(outputs)  # Will raise an exception if the :outputs: object is not JSON-serializable
    return outputs
