I’ve used @ScottWorld’s excellent suggestions from this post to append values to a multi-link field (whether it already has values or not, so slick). Now I’m trying to do the same for a collaborator field, and I’m running into trouble. You can set a collaborator field by providing the name or email address of the Airtable user, but it seems like appending to an array of collaborators requires you to use their internal IDs, which I’m not sure how to look up. I’ve tried a variety of array merge/append tricks, but nothing seems to work. Anyone know how to either append to a collaborator field using email address or name, or lookup the internal Airtable user id from an email address to use for the append operation?
