| `ad_group_id` | string or SelectItem      | Yes      | -       | Ad group (line item) to promote the posts in.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                |
| `tweet_ids`   | string or array of string | Yes      | -       | IDs of the posts to promote (list or comma-separated string, up to 50). Use an organic post's ID from x\_ads\_list\_posts, or a Promoted-only post created by x\_ads\_create\_post or by one of the format ad nodes with post\_only enabled. X rejects posts that do not fit the ad group's objective; notably, WEBSITE\_CLICKS ad groups only accept posts containing a website link or card. Take the IDs from the id\_str or tweet\_id field, never a numeric id: X ids are 64-bit and any tool that stores them as a number rounds them into a post that does not exist. |
