Currently with the SE api, you can get all the answers on a specific question using /question/ID/answers
. You can also get all the answers by a specific user on a post using /users/ID/answers
.
The problem is I don't see anyway to get all the answers on a specific question by a specific user.
I do know that I can filter the api response but my target question is the PPCG sandbox in which there are much more than a 100 questions meaning I could possible have to do up to 19 requests to get all the answers considering the maximum page size is 100.
