hah is an opaque value returned by the server to track a paging cursor

. It is commonly used in web development to implement pagination for large datasets. The server generates a unique hah value for each page of data and sends it back to the client along with the requested data. The client can then use this hah value to request the next page of data. The hah value is typically an encoded string that contains information about the current page and the data it contains. The client does not need to understand the hah value, it simply passes it back to the server to request the next page of data
