Hello @Theolodewijk,

Is my_key in your code the actual SendGrid API Key? If so, it should not be, instead it should be the name of the environment variable where your API key is stored, such as SENDGRID_API_KEY.

With Best Regards,

Hi,
Although I followed the instructions appear on SendGrid official web https://app.sendgrid.com/guide/integrate/langs/php, I have the same problem:
401 Array ( [0] => HTTP/1.1 401 Unauthorized [1] => Server: nginx [2] => Date: Sat, 04 May 2019 17:22:44 GMT [3] => Content-Type: application/json [4] => Content-Length: 88 [5] => Connection: keep-alive [6] => Access-Control-Allow-Origin: https://sendgrid.api-docs.io [7] => Access-Control-Allow-Methods: POST [8] => Access-Control-Allow-Headers: Authorization, Content-Type, On-behalf-of, x-sg-elas-acl [9] => Access-Control-Max-Age: 600 [10] => X-No-CORS-Reason: https://sendgrid.com/docs/Classroom/Basics/API/cors.html [11] => [12] => ) {"errors":[{"message":"Permission denied, wrong credentials","field":null,"help":null}]}

Where should I locate the sendgrid.env file?

Which text should include in it exactly?

The 401 problem is about wrong credentials.

And you can look at the JSON response that you paste.

To debug the problem conveniently, I suggest that you can set the SenfGrid key directly instead of using environment variables at this moment on the following code snippets:

```php
.....
$sendgrid = new \SendGrid('your_sendgrid_key');
.....

Hello @Theolodewijk, @orhagashi,

Another thing you may try to rule out the API Key as the cause, if you don't want to include the API Key directly as @peter279k suggested, is to make a call using our interactive docs. If your call is successful there, it means that the issues is the API Key is not getting set properly in your code.
