How to receive the body of the answer?
You can retrieve the body by adding a query parameter of filter=withbody. For example, when /2.2/answers/43919322?order=desc&sort=activity&site=stackoverflow in URL of your question is used, the URL is as follows.
https://api.stackexchange.com/2.2/answers/43919322?order=desc&sort=activity&site=stackoverflow&filter=withbody&access_token=#####&key=#####
If you want to retrieve the data using curl, you can use this.
curl "https://api.stackexchange.com/2.2/answers/43919322?order=desc&sort=activity&site=stackoverflow&filter=withbody&access_token=#####&key=#####" | gunzip
