It seems that there's some confusion about the
verify-purchase API methods.
download-purchase is for buyers to generate their download link for a purchase. This method requires the use of the buyer's username and API key.
verify-purchase is for sellers to retrieve details about a purchase. This method requires the use of the seller's username and API key.
Hope that clears things up!
That's what I thought, I mean it makes sense to be that way, but it would have been nice if there was a way to provide a download link without the client's API, a download link for my items only per say, only what he / she purchased from me, not all his downloads.
Also, another good thing would be if there were some info on the updates in the API, a way to inform the clients that we updated our items.
