Syntax to specify time grain for field for JSON API

[justin-tay]

What is the syntax to specify an attribute for a field for JSON API?

/playerStats?fields[playerStats]=gameOn,highScore&sort=highScore

For instance if I want to get the gameOn field to use the MONTH time grain.

For the filter I see that using gameOn[grain:MONTH]=='2020-08' in the filter seems to work but this same syntax in the sparse fieldset does not work.

JSON-API unfortunately doesn't support parameterized attributes. That is only a feature in GraphQL. You would need to create separate attributes in your model for each time grain in JSON-API (single grain per attribute).
