Currently, it seems to be impossible to query a notion API resource in a workflow setting "start_cursor" parameter in the body JSON. This blocks the ability to treat pagination as it should.
It's only possible to set the "filter" body JSON parameter.
As a workaround, I'm using a generic HTTP Request Resource, which removes all the fun of having provider out-of-the-box integrations.
It would be nice to have the option of customizing this kind of fields.
I see what you mean. Unfortunately, I'd also recommend using our generic REST api integration instead of the notion integration as a workaround. I'll reach back out when our team ships a fix for this bug
