Before usage

To get started with the SDK, you'll need:

Terminal key - seller's terminal key;
Password - terminal password (optional);
Public key – public key. Used to encrypt data. Required to integrate your application with Tinkoff Internet acquiring.

These values are issued in your personal account after connecting to Tinkoff Internet Acquiring.

SDK allows you to configure operating mode (debug / prod), by default - debug. The SDK also allows you to configure request proxying, by default all requests go to Tinkoff servers.

Credential

To configure the operation mode, set the following parameters:

final TinkoffAcquiring acquiring = TinkoffAcquiring(
  TinkoffAcquiringConfig.credential(
    terminalKey: terminalKey,
    password: password, // if not passed, it will work in passwordless mode
    isDebugMode: false,
  ),
);

Token

If your request is signed on the side, then you can use the following constructor:

final TinkoffAcquiring acquiring = TinkoffAcquiring(
  TinkoffAcquiringConfig.token(
    terminalKey: terminalKey,
    isDebugMode: false,
  ),
);

In this case, you need to add signToken to the request model:

InitRequest(
  signToken: ...,
  ...
)

request.copyWith(signToken: ...);

Proxy

If you want to use a proxy, use the following constructor:

final TinkoffAcquiring acquiring = TinkoffAcquiring(
  TinkoffAcquiringConfig.proxy(
    proxyDomain: 'myserver.com',
    proxyPath: '/acquiring',
    isDebugMode: false,
    globalHeaders: <String, String>{...},
    mapping: (AcquiringRequest request, bool isDebugMode) {
      if (request is InitRequest) {
        return const ProxyRequest(
          headers: <String, String>{...},
          methodPath: '/Init',
        );
      }

      ...

      return null;
    },
  ),
);
