recommendationTypes property

List of eligible recommendation_types to generate.

If the uploaded criteria isn't sufficient to make a recommendation, or the campaign is already in the recommended state, no recommendation will be returned for that type. Generally, a recommendation is returned if all required fields for that recommendation_type are uploaded, but there are cases where this is still not sufficient. The following recommendation_types are supported for recommendation generation: KEYWORD, MAXIMIZE_CLICKS_OPT_IN, MAXIMIZE_CONVERSIONS_OPT_IN, MAXIMIZE_CONVERSION_VALUE_OPT_IN, SET_TARGET_CPA, SET_TARGET_ROAS, SITELINK_ASSET, TARGET_CPA_OPT_IN, TARGET_ROAS_OPT_IN

Required.
