dwolla-php

The official PHP SDK for the Dwolla API. Supports server-side PHP calls to Dwolla’s endpoints with typed models, simple client helpers, and OAuth token handling to manage customers, funding sources, transfers, webhooks, and more.

Important

Beta Release – This SDK is currently in beta. We have run smoke coverage (SDK build/clients) and a sandbox getting-started flow (root, list customers, create unverified customer, add funding source). Broader operation coverage and retry wiring are still in progress. Breaking changes may occur as we continue hardening and expanding tests; use with caution in production. We welcome beta users to integrate, report issues, and help us catch edge cases.

Summary

Dwolla API: Dwolla API Documentation

SDK Installation

The SDK relies on Composer to manage its dependencies.

To install the SDK and add it as a dependency to an existing composer.json file:

composer require "dwolla/dwolla-php"

SDK Example Usage

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Operations;

$sdk = Dwolla\Dwolla::builder()->build();

$request = new Operations\CreateApplicationAccessTokenRequest(
    grantType: Operations\GrantType::ClientCredentials,
);
$requestSecurity = new Operations\CreateApplicationAccessTokenSecurity(
    basicAuth: '<YOUR_API_KEY_HERE>',
);

$response = $sdk->tokens->create(
    request: $request,
    security: $requestSecurity
);

if ($response->object !== null) {
    // handle response
}

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
`clientID` `clientSecret` `tokenURL`	oauth2	OAuth2 Client Credentials Flow

You can set the security parameters through the setSecurity function on the SDKBuilder when initializing the SDK. For example:

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Components;

$sdk = Dwolla\Dwolla::builder()
    ->setSecurity(
        new Components\Security(
            clientID: '<YOUR_CLIENT_ID_HERE>',
            clientSecret: '<YOUR_CLIENT_SECRET_HERE>',
        )
    )
    ->build();



$response = $sdk->root->get(

);

if ($response->root !== null) {
    // handle response
}

Per-Operation Security Schemes

Some operations in this SDK require the security scheme to be specified at the request level. For example:

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Operations;

$sdk = Dwolla\Dwolla::builder()->build();

$request = new Operations\CreateApplicationAccessTokenRequest(
    grantType: Operations\GrantType::ClientCredentials,
);
$requestSecurity = new Operations\CreateApplicationAccessTokenSecurity(
    basicAuth: '<YOUR_API_KEY_HERE>',
);

$response = $sdk->tokens->create(
    request: $request,
    security: $requestSecurity
);

if ($response->object !== null) {
    // handle response
}

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or throw an exception.

By default an API error will raise a Errors\APIException exception, which has the following properties:

Property	Type	Description
`$message`	string	The error message
`$statusCode`	int	The HTTP status code
`$rawResponse`	?\Psr\Http\Message\ResponseInterface	The raw HTTP response
`$body`	string	The response content

When custom error responses are specified for an operation, the SDK may also throw their associated exception. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the create method throws the following exceptions:

Error Type	Status Code	Content Type
Errors\UnauthorizedException	401	application/json
Errors\APIException	4XX, 5XX	/

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Errors;
use Dwolla\Models\Operations;

$sdk = Dwolla\Dwolla::builder()->build();

try {
    $request = new Operations\CreateApplicationAccessTokenRequest(
        grantType: Operations\GrantType::ClientCredentials,
    );
    $requestSecurity = new Operations\CreateApplicationAccessTokenSecurity(
        basicAuth: '<YOUR_API_KEY_HERE>',
    );

    $response = $sdk->tokens->create(
        request: $request,
        security: $requestSecurity
    );

    if ($response->object !== null) {
        // handle response
    }
} catch (Errors\UnauthorizedExceptionThrowable $e) {
    // handle $e->$container data
    throw $e;
} catch (Errors\APIException $e) {
    // handle default exception
    throw $e;
}

Server Selection

Select Server by Name

You can override the default server globally using the setServer(string $serverName) builder method when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:

Name	Server	Description
`prod`	`https://api.dwolla.com`	Production server
`sandbox`	`https://api-sandbox.dwolla.com`	Sandbox server

Example

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Operations;

$sdk = Dwolla\Dwolla::builder()
    ->setServer('prod')
    ->build();

$request = new Operations\CreateApplicationAccessTokenRequest(
    grantType: Operations\GrantType::ClientCredentials,
);
$requestSecurity = new Operations\CreateApplicationAccessTokenSecurity(
    basicAuth: '<YOUR_API_KEY_HERE>',
);

$response = $sdk->tokens->create(
    request: $request,
    security: $requestSecurity
);

if ($response->object !== null) {
    // handle response
}

Override Server URL Per-Client

The default server can also be overridden globally using the setServerUrl(string $serverUrl) builder method when initializing the SDK client instance. For example:

declare(strict_types=1);

require 'vendor/autoload.php';

use Dwolla;
use Dwolla\Models\Operations;

$sdk = Dwolla\Dwolla::builder()
    ->setServerURL('https://api.dwolla.com')
    ->build();

$request = new Operations\CreateApplicationAccessTokenRequest(
    grantType: Operations\GrantType::ClientCredentials,
);
$requestSecurity = new Operations\CreateApplicationAccessTokenSecurity(
    basicAuth: '<YOUR_API_KEY_HERE>',
);

$response = $sdk->tokens->create(
    request: $request,
    security: $requestSecurity
);

if ($response->object !== null) {
    // handle response
}

Maturity

This SDK is currently in beta; expect potential breaking changes while we stabilize. We follow Semantic Versioning for published versions, but until GA we recommend pinning to an exact version and validating in your environment.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
