    // Like this:
add_filter('wpcf7_hidden_field_value', 'my_function_to_change_hidden_field_value');

// or like this, if your field has an ID of "example_id"
add_filter('wpcf7_hidden_field_value_example_id', 'my_function_to_change_hidden_field_value');

function my_function_to_change_hidden_field_value($value) {
	return 'a different value';
}

    After half an hour of searching the problem because it did not work:
    ID means literally the ID and not the name of the field

    [hidden Fieldname id:FieldID “—“]
    add_filter(‘wpcf7_hidden_field_value_FieldID‘, …)
