Hello Andrey,

I will check the documentation again to find the solution.

Just for your knowledge:
There is some info like pincode i am having to call the API one by one for each entry . Now you think , because i know you also have technical knowledge so you can think . How time taking process to calling an api 100k time for the 100k entry and how the server will react you can think about it.
I have suggested mark when i was in talk with him that instead of fetching the data from the API we should store it inside our own database, so whenever we need to fetch it we can fetch without long time waiting.May be they do have some genuine reason to denied this suggestion and we haven’t did it.
