Hi,
I wonder if you can give us a hand on this matter :)
We are trying to validate that a GET api call comes with at least one of two defined filter fields with valida data, but don't know how to accomplish this and what's the best way.
Let me give you and example, imagine we have a user entity with 2 filter fields: id and email. We need only one of them with a non empty right value, and we need a validation in a GET request before making a custom filter.
Thanks a lot!

Hey @SamuelVicent!

Sorry for the very slow reply. I'm not aware of a native feature for this, which is ok - it just means that we need to do a bit of work ourselves. If you're creating a custom filter to handle this, then that might be the place to add this logic. The flow internally looks like this:

GET request is made. API Platform calls the data provider for the correct API Resource class.
That class is ultimately responsible for returning the array of results, which includes (if applicable) reading any query parameters and using them to build (filter) the results. For Doctrine, there is a built-in entity provider that reads the query parameters, calls the filters and passes them the query param values.

So custom validation on the query parameters could live in a data provider or (for Doctrine) in custom filter class: https://symfonycasts.com/screencast/api-platform2-extending/entity-filter-logic

Either way, what you would do is this:

If invalid, the simplest would be to ignore all of the filters and return the full result set or an empty set. The downside would be that the user doesn't get any feedback about what they did wrong.
If that's important, I think you can, at any time, throw a BadRequestException to trigger a 400 response. I can't remember, but I think the message you pass to this object is ultimately shown to the user.

Let me know if this helps!

Cheers!
