How to get history of changes to contact OR history of changes to field value through API?
Let's say I have a custom field for my contacts named "Other_Phone". Its value for Jane Doe was 555-1234 in October, then got changed to 999-7410 in December.
Is there way way I can (using the API) get the previous value for that field for Jane Doe? (Ex: some kind of query or function where I say "getRecords for ID xxxxxx on date 2021-10-01 or similar)?
Or, failing that, is there any way through the API to simply see a list of changes made to Jane Doe's contact record, and then I can parse out the old field value in code?
Thanks,
Richard
