Is it possible to send the prices for all marketplaces with different prices in one feed at the same time? We quickly reach the limits if we send one feed per marketplace.
Not that I can think of. But you could likely send them through the different Endpoints.

We send the price every about 3 minutes. The problem is that the limit of 30 affects not only the prices but all api calls.
We have a lot of products and therefore a lot of price changes on the products.
