I feel like I’m missing something obvious, but I’ve tried all sorts of paging options etc and the /wp-json/gf/v2/entries endpoint only returns 10 items, even if the “total_count” result is in the hundreds. If I filter or change sorting, it returns the first 10 and then skips the rest.
FWIW I was able to work around this by adding the paging[page_size]=100 to the REST query parameters. I guess the default is 10, which seems undocumented in my searches. I thought sure I had tried this before, but I guess not! If this isn’t a bug, then I’ll rework my calls to use paging to get complete results, but for now I don’t expect to get more than 40-50 results.
