rest_api: extend the endpoint configuration allowing to pass `data` for the POST requests

[francescomucio]

Source name

rest_api

Describe the data you'd like to see

GraphQL APIs and in general endpoints used with the POST method, requires additional data to be passed in the body of the requests (in the case of graphQL APIs, this data will be the query for the endpoint).

What we need:

• [ ] A new argument for endpoint to pass the data.
• [ ] For incremental resources the data should also be modified to load the most recent results

I would be nice to validate that POST requests have the data parameter, but I am wondering if out there there are weird POST apis which need no body

Hey @francescomucio I think it's already partly implemented in https://github.com/dlt-hub/verified-sources/pull/431. Could you take a look and see if this can work for you? By the way I was thinking that maybe for GraphQL we'd need another "source", parallel to rest_api.
