The parameters passed to the API were invalid. Check your inputs!

[lmquang]

Hello,
This is my code:

$to           = 'abc@yahoo.com';
$subject      = 'offline';
$html_message = 'test offline';

$data = array(
    'customer' => 'John Smith',
    'url' => 'http://laravel.com'
);

Mailgun::send('mail', $data, function($message) use ($to,$subject)
{
    $message->to($to, 'John Smith')->subject($subject);
});

But it show error which is:
The parameters passed to the API were invalid. Check your inputs!
Can you explain ?
Thank you

Hi @ivkean,
Do you have a mail.blade.php template in your views directory?

[lmquang]

yes, and it's code:
{{ $customer }}

[Bogardo]

All required fields in the configuration file are entered?

@ivkean Have you managed to solve the issue?

[lmquang]

@Bogardo
Not yet, i set up mailgun account free. Is that why i can not send mail ?

[CupOfTea696]

I have the same issue. I checked my config file a million times. I always get those kinds of errors.

I get the error The parameters passed to the API were invalid. Check your inputs! on Mailgun::lists()->create() I'm using the exact code from the documentation.
When I call Mailgun::lists()->all(); everything works perfectly.

[CupOfTea696]

I found the error. The problem is that the Mailgun-PHP package just throws that exception and disregards the data it gets. I edited the file where the error was and just did a var_dump() of the response it actually gets. Here's what came out:

{
  "message": "The 'address' parameter should be a valid email address"
}

Maybe you could find a way to catch the exception and add the data from the response? Because otherwise with errors like this you just have no clue what went wrong.

[Bogardo]

@CupOfTea696 I'm glad you found the problem.
What kind of list 'address' did you create in the Mailgun Control Panel?
Never mind, you were creating a new list... :)

And which file did you change to get the error message?

[Bogardo]

@CupOfTea696 I see you're already creating a PR on the mailgun/mailgun-php repo.

They should probably do something like this:

public function responseHandler($responseObj){
        $httpResponseCode = $responseObj->getStatusCode();
        if($httpResponseCode === 200){
            $data = (string) $responseObj->getBody();
            $jsonResponseData = json_decode($data, false);
            $result = new \stdClass();
            // return response data as json if possible, raw if not
            $result->http_response_body = $data && $jsonResponseData === null ? $data : $jsonResponseData;
        }
        elseif($httpResponseCode == 400){
            $response = json_decode((string)$responseObj->getBody(), false);
            if (isset($response->message)) {
                throw new MissingRequiredParameters(EXCEPTION_MISSING_REQUIRED_PARAMETERS . " " . $response->message);
            }
            throw new MissingRequiredParameters(EXCEPTION_MISSING_REQUIRED_PARAMETERS);
        }
        elseif($httpResponseCode == 401){
            throw new InvalidCredentials(EXCEPTION_INVALID_CREDENTIALS);
        }
        elseif($httpResponseCode == 404){
            throw new MissingEndpoint(EXCEPTION_MISSING_ENDPOINT);
        }
        else{
            throw new GenericHTTPError(EXCEPTION_GENERIC_HTTP_ERROR, $httpResponseCode, $responseObj->getBody());
        }
        $result->http_response_code = $httpResponseCode;
        return $result;
    }

[CupOfTea696]

Yeah, that's pretty close to what I have. I'll create a pull request in a sec.

[Bogardo]

@CupOfTea696 There is no need to add this to the EXCEPTION_INVALID_CREDENTIALS and EXCEPTION_MISSING_ENDPOINT these are fine the way they are. Just the EXCEPTION_MISSING_REQUIRED_PARAMETERS should do.

[CupOfTea696]

Trust me, I had a 404 error earlier which I wouldn't have figured out if it wasn't for the response data. It just said the url was wrong, while the actual problem was that I was trying to get() a list that didn't exist (because I thought you could check if the list existed that way but instead it throws this error).

[Bogardo]

The InvalidCredentials exception returns the message "Your credentials are incorrect." which should be sufficient.
The MissingEndpoint exception does return the message Mailing list abc@abc.com not found when trying to get a non-existent resource.

But when you try to access a completely non-existent url/path like /test you get the following response:

Which isn't really what you want.

Hi @Bogardo ,

I faced same issue ("The parameters passed to the API were invalid. Check your inputs!") when I tried to add a domain that exists already in the same account. I updated responseHandler function to get correct error message. Just want to check whether the code is merged into main repo or not.
