Examples
Sync COGs for a survey
This query is used by a client to sync COGs for a specific survey with COGs stored on the server. This query will return up to the first 1,000 COGs in a survey that are different from the COGs held by the client. To retrieve the remaining COGs, a client should call this query repeatedly, passing in the full set of content hashes for COGs it holds, until no more COGs are returned, or the remaining count returned is 0.
Try this example in GraphiQLquery SyncSurveyCogs {
