How the deliveries of one integration went over a period: the deliveries created in it by current status, how many were tried more than once, and the largest groups of failed and unfinished ones by response code and reason. The counts cover every delivery of the period, not one page. Call it to size a problem, then list_integration_deliveries for the records behind a count; per day, week or month: get_integration_stats_timeline.

The period is whole UTC days, at most 31, with from at most 30 days before today. Statuses are the current ones, not the ones at the end of the period. Zero deliveries does not mean the integration works, or that nobody sent the form: a response that never reached this integration leaves nothing here.
