Create Ad From Post

Promotes posts that already exist in an X Ads ad group, up to 50 at once, creating the ads (promoted tweets)

Promotes posts that already exist in an X Ads ad group, up to 50 at once, creating the ads (promoted tweets). Use it with organic posts from x_ads_list_posts, or with posts built by the format ad nodes using post_only. To create a new post and promote it in one step, use x_ads_create_text_ad, x_ads_create_image_ad, x_ads_create_video_ad, or x_ads_create_carousel_ad.

Inputs

Field	Type	Required	Default	Description
account	DynamicAccount	Yes	-	Select the X Ads account that owns the ad group.
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.

SelectItem

Field	Type	Required	Default	Description
value	string	Yes	-	The value of the selectable item.
label	string	Yes	-	The label of the selectable item, used for display purposes. If not provided, defaults to the value.

Output

Type: List[Dict]

Returns the created promoted tweet records.
