ACP - Questions about Product Feed size limits and update strategy

API
1

Hello,

I’m implementing a Product Feed for the Agentic Commerce Protocol and have a couple of quick questions:

  1. Is there a maximum file size for a Product Feed? If so, are there recommended limits or best practices for splitting large feeds?

  2. For updates, do we need to send the full product catalog every time, or are incremental (delta) updates with only changed products supported or recommended?

Also, if there is a dedicated place in the OpenAI community or documentation to ask Product Feed–related questions, please let me know.

Thanks in advance!
