Fatal error: Uncaught DwollaSwagger\ApiException

Hello Team,
I want to connect Dwolla to my Wordpress site, but after adding code and loading the page it shows this error (please see attached image).

This is my code:
require get_stylesheet_directory() . ‘/vendor/autoload.php’;
include get_stylesheet_directory() . ‘/dwolla-swagger-php/DwollaSwagger.php’;
DwollaSwagger\Configuration::$username = ‘I’;
DwollaSwagger\Configuration::$password = ‘’;
$apiClient = new DwollaSwagger\ApiClient(“https://api-sandbox.dwolla.com”);
$customersApi = new DwollaSwagger\CustomersApi($apiClient);

$customer = $customersApi->create([
‘firstName’ => ‘Jane’,
‘lastName’ => ‘Merchant’,
‘email’ => ‘jmerchant@nomail.net’,
‘type’ => ‘receive-only’


Did I use the wrong code? Sorry I’m new so I don’t understand much

Hi @devrentaraj

That error looks like it’s saying you are lacking valid authentication credentials. It looks like you’re trying to call the sandbox api, have you set up a sandbox account in order to obtain you key and secret?


Hmm…looks like @devrentaraj does have the Sandbox credentials in his code. A 401 error usually means there’s something wrong with the request-body.

@devrentaraj, you should be able to catch the error and get the JSON response-body by wrapping the request in a try/catch and display the error response by calling the getResponseBody() method.


    $new_customer = $customersApi->create([
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getResponseBody(), "\n";

Yes, I already have the Sandbox credentials, please see attached image below.

I tried catching the error as per your instructions and I get the following error:

Hi @devrentaraj

I erased your creds from the your posts so it won’t be shared with the public.

I was also wondering if you could try formulating your code the way it is in the Swagger “Quick start” section of the Readme

I’m seeing a few minor differences in your original req that may be throwing things off

Hi @kmoreira
Thank you for responding, but I can’t access this page Readme

Hi, I was missing access token, I added it in my code and now it worked for me. Thank you so much!

Our pleasure. And apologies for the link. Here is the correct link in case anything else comes up GitHub - Dwolla/dwolla-swagger-php: Autogenerated PHP SDK client for API V2

Hello @kmoreira,
Can I ask you to delete some accounts that I no longer need from my sandbox account? I can only change them to suspended and deactivate but I want to remove it completely from my account.

Hi @devrentaraj

While you can deactivate and suspend a Customer, the functionality to delete a Customer isn’t supported as per the data retention guidelines that Dwolla is subject to within the USA.

Hi @kmoreira, I got it, thank you very much!
