# Can I use mixed form types in the same bulk-upsert request?

Learn whether you can include different form types in a single bulk-upsert request.

No. You can’t include forms of different types (for example, `1099-NEC`, `1099-MISC`, `1099-K`) in the same `bulk-upsert` request. However, you can include forms of multiple Issuers in the same request, if all of them are of the same form type.
