# Better handling of rss_opts for POST Campaigns

We fixed a bug in the [POST Campaigns endpoint](/developer/marketing/api/campaigns/create) regarding invalid request body parameters for non-rss campaigns.

We were receiving requests that were attempting to create non-`rss` type campaigns with an `rss_opts` field. These requests were throwing exceptions and returning `500` status codes to users. We now return a `400` status code if `rss_opts` are provided for non-`rss` type campaigns.
