What about passing

[
  'email' => null,
  'invoice_settings' => [
    'default_payment_method' => 'null',
  ],
]

As in, this method didn't seem recurring or able to handle non top-level params

I don't quite follow -- this PR adds a recursive call https://github.com/stripe/stripe-php/pull/933/files#diff-d6b577df0148860a08e6dfb3025bd0d0R52

and this test case covers non top-level params -- everything is nested one level under "foo".

static::assertTrue('bar' === $result['foo'][0]);
static::assertTrue('' === $result['foo'][1]);
static::assertTrue('' === $result['foo'][2]);
static::assertTrue('baz' === $result['foo'][3]);
}
}
