Is there a way to get the raw response?

[JensDeMuynck]

For example: $rawResponse = $CashEntry->save()->getRawResponse() ?

As far as I can see from looking at the save and fill methods, the raw response is not preserved.

Your best option would be to use the insert or update method directly, but since the fill method is protected you cannot use it directly without some workaround.

Potential workaround:

$cashEntry = new CashEntry($connection);

$rawResponse = Closure::bind(function () use ($cashEntry) {
    $data = $cashEntry->update();

    $cashEntry->fill($data);

    return $data;
}, null, CashEntry::class)();

Perhaps the Guzzle middleware option could be helpful in you case.
