createPayment method

Future<Payment> createPayment({
  1. required CreatePaymentRequest request,
  2. String? authToken,
})

Creates a payment using the provided source.

You can use this endpoint to charge a card (credit/debit card or Square gift card) or record a payment that the seller received outside of Square (cash payment from a buyer or a payment that an external entity processed on behalf of the seller).

Implementation

Future<Payment> createPayment({
  required CreatePaymentRequest request,
  String? authToken,
}) async {

  authToken ??= authenticationService.getCachedToken()?.accessToken;

  Map<String, String> headers = {
    "Authorization": "Bearer ${authToken ?? ""}",
    'Content-Type': 'application/json; charset=UTF-8',
    'Accept': 'application/json',

  };

  Uri endpoint = Uri.https(
      baseUrl, "/v2/payments");

  //print (endpoint.toString());

  var response = await
  http.post(endpoint, body: jsonEncode(request.toJson()), headers: headers);

  if (response.statusCode == 200) {
    print (jsonDecode(response.body));
    return SquarePaymentResponse.fromJson(jsonDecode(response.body)).payment!;
  }
  else {
    print (response.body);
    throw PaymentException(statusCode: response.statusCode, message: SquarePaymentResponse.fromJson(jsonDecode(response.body)).errors?[0].detail?.toString());
  }
}
