Hi Richard, I see this is a post from the summer, I’m just catching up on some past posts now that the Gibbon team is back in school. This process should still work for custom fields in v22 as well. If you’re writing an import for something other than Users, you’d need to update the table: and <code class="CodeInline">primaryKey: fields in the import file to point to a different table (eg: Staff).
I’ve made a note to add example imports for each of the new custom field contexts for v23. Thanks!
