I am trying to use the changes endpoints (ex: https://www.trade-tariff.service.gov.uk/api/v2/commodities/0207600510/changes) but it’s unclear to me how this works.
The documentations is not very helpfull so what I am interested in is to understand:
1.what kind of changes can be found here, only measure changes?
2.are there any fields that are not changed like maybe id or origin or anything else?
3.what does “operation” field represent (are these abbreviations for something?) and are there any other values than “C” and “U” for this field?;
4.what does “operation_date” represent - maybe the date when the change occurred?;
5.is the measure id the same as the one from commodity details? looks like some of them are not found in commodity details( endpoint https://www.trade-tariff.service.gov.uk/api/v2/commodities/0207600510), so I’m confused. Otherwise how can I identify the measure I need to change?
