Pagination
It might happen that some of the GET requests return a very large response of values. With the use of offset and limit you can set up a pagination which help you to limit the results.
offset is the start value, per default is 0
limit is value end value.
For example you can use this pagination to GET your orders /openapi/v2/orders:
GET /openapi/v2/orders ->
GET /openapi/v2/orders&offset=0&limit=20 -> This result will give you the 0-20 latest orders
GET /openapi/v2/orders&offset=20&limit=20 -> This result will give you the 20-40 latest orders.
