Any tutorials for a different way to update multi-reference fields without PATCH and Zapier?

[The_Attributes (Team Attributes)]

Still looking for a solution on this. I’m currently getting an error: ValidationError: Validation Failure (HTTP Status Code: 400)

This is the JSON I have setup:

{"fields":{
"reviewees":[{{188846960__TF -> TM 3as Webflow Item ID Formatted (from Trust Fall Results)}}]}
}

https://api.webflow.com/collections/6421dc821bb59c40aab6cd4f/items/{COLLECTION ID GOES HERE}?live=true

I saw you might have a solution @Drew_Schafer from this post?
