I want to download all the records from the open group.
I use wall.get, and download 100 (max.) By increasing the offset while the query succeeds. It works well for downloading, but in order to check whether one more record was added, it is necessary to make requests for all records again - this is a long and inefficient process.
Is it possible to somehow easier survey the number of records in one request?

And is it possible to get a list of changes in the group that occurred during a specified time?

    Got it! You just need to set the offset to 0, count to 1 and remove the filter. In the response object, the count field shows the number of messages.

    wall.get?domain=autism1&offset=0&count=1&extended=0&params[v]=5.50 response: { count: 2155,
