}Create an Engage feed
Save a new Engage feed on the account: a set of keywords, a public X
list, or one of the account’s own contact lists. The feed appears in
GET /v1/engage/feeds, can be fetched with
GET /v1/engage/feeds/{id}/posts, and shows up for the person in the
SuperX app’s Engage tab.
The new feed does NOT become the feed the app has open: the API must
not move someone’s view while they are working in it. The response
carries the account’s current active feed unchanged.
Send exactly ONE source: keywords (1-5), x_list_id or
x_list_url, or list_id. type must agree with the fields you
send. An X list is looked up live and only PUBLIC lists are accepted,
so those calls also consume one unit of the tighter enrichment
allowance; keyword and contact-list feeds consume none. Up to 8 feeds
per account. Works for your main account or any account linked to it
(account_id); accounts shared with you are read-only.
