How To Save Data From Remote APIs To ACF?

I've been attempting to ingest remote data from an api partner into Wordpress. To data I've used wpallimport plugin, but it's quite limited.

How would one connect with a remote api and then save the data to a an ACF field either one time or periodically?

I've test out wp_remote_get($apiUrl); and even created a POC but saving the data to the WP database has not been successful yet.
