I use https://api.stackexchange.com/docs. To get a sample question, I use the address https://api.stackexchange.com/2.2/questions/6827752?&site=stackoverflow. Thanks to this, he gains a question. The following page shows https://api.stackexchange.com/docs/types/question that with the default filter, the question will not have a body. I know I use a filter to get a body filter=withbody that is, the address comes out

https://api.stackexchange.com/2.2/questions/6827752?&site=stackoverflow&filter=withbody

Now I would like to get answers to the question. That's why I want to use a filter filter=withanswers. This address

https://api.stackexchange.com/2.2/questions/6827752?&site=stackoverflow&filter=withanswers

returns an error

{
  "error_id": 400,
  "error_message": "Invalid filter specified",
  "error_name": "bad_parameter"
}

How to get answers or comments using a filter?

I think that 2 patterns can be thought for your solution. One is a method using custom filter. Another is a method using the endpoint for retrieving answers.

Pattern 1 :

You can create a custom filter for retrieving answers and answer's body using the endpoint of https://api.stackexchange.com/2.2/questions/### questionId ###.

  1. You can create the custom filters at http://api.stackexchange.com/docs/create-filter.
    • In your case, you can use this.
      • question.answers;answer.body;question.body was used as including filters.
      • The delimiter is ;.
    • As a result, you retrieve "filter": "!T*hPNRA69ofM1izkPP".
    • When you use the filter, please do URL encode it.
      • !T*hPNRA69ofM1izkPP becomes %21T%2ahPNRA69ofM1izkPP.
  2. You can retrieve answers and answer's body using the endpoint.
    • When the question ID of your question is used, it's https://api.stackexchange.com/2.2/questions/6827752?&site=stackoverflow&filter=%21T%2ahPNRA69ofM1izkPP.

Result of pattern 1

When you can access to https://api.stackexchange.com/2.2/questions/6827752?&site=stackoverflow&filter=%21T%2ahPNRA69ofM1izkPP, you can get answers and answer's body.

Pattern 2 :

As the endpoint for retrieving answers, you can use /questions/{ids}/answers. If the question ID is 6827752 in your question, the endpoint is as follows. In this case, in order to retrieve answer's body, filter=withbody is used.

Result of pattern 2

If this was not useful for you, I'm sorry.
