StatusCode.hpp
namespace verifone_sdk
struct StatusCode
- Known status codes. Purposes of a predefined status code:
- The error can be handled heuristically by the POS, e.g., recieving device_not_ready should retry the command after a short delay without user input.
- The POS may want to translate the error message itself, instead of the localized prompts that we provide.
- The POS might need to display a different prompt than the normal error message, e.g., show a “Display Configuration” button in addition to the standard “Cancel” and “Retry” buttons for the other error prompts.
Public Static Attributes
static constexpr int32_t SUCCESS
- The constant status code for success.
static constexpr int32_t GENERAL_ERROR
- An error code that is not defined elsewhere. The message should be displayed to the user with options to retry, abort, or wait.
static constexpr int32_t DEVICE_NOT_FOUND
- A device is configured but could not be found using the known connections. The message should be displayed to the current user so that they can make sure that the device is turned on, connected, and ready.
static constexpr int32_t DEVICE_NOT_READY
- The device can be contacted, but it is still loading or otherwise preparing. Resend the command after a brief delay to allow it to finish preparing.
static constexpr int32_t DEVICE_CONNECTION_FAILED
- The connection was not able to be established with the device. This can happen because the device cannot pair with another device, or the network fails, or a variety of reasons. This should include an option to launch DeviceConfiguration() for more information.
static constexpr int32_t DEVICE_CONNECTION_LOST
- The connection to the device has been lost unexpectedly.
static constexpr int32_t DEVICE_BUSY
- The device is currently handling other commands or interacting with other devices and cannot perform the request. The request should be retried after a period of time, and it might be helpful to display the error to the user.
static constexpr int32_t DEVICE_WARNING
- A general warning about the device, such as a low battery, with a message that should be displayed to the user, but does not require input.
static constexpr int32_t DEVICE_ERROR
- A general error has occurred with the device, such as powering off due to insufficient battery. The message should be displayed to the user, and should include an option to launch DeviceConfiguration() for more information.
static constexpr int32_t DEVICE_REJECTED_PAIRING
- Unable to pair, unexpected server response to request. Only occurs when the host or a server decides which devices are allowed to connect to this terminal. This is rare. This cannot be retried, and generally implies that tech support should be contacted.
static constexpr int32_t NOT_ALLOWED
- The command requested is not allowed, most likely due to the permission granted to the application or the user.
static constexpr int32_t CANCELLED
- The operation was cancelled on the customer-facing display.
static constexpr int32_t ABORTED
- The operation was aborted by using the abort command.
static constexpr int32_t REAUTHENTICATION_REQUIRED
- Reauthenticaton required. This can occur when the current configuration is now out-of-date and must be updated, or the terminal must reauthenticate with the host to continue working. The POS can either call Login() automatically, or prompt the user to login.
static constexpr int32_t CONTACT_ACQUIRER
- Contact acquirer. Terminal should provide any relevant details for the merchant when contacting the acquirer, including phone #, account information, and the reason.
static constexpr int32_t INVALID_STATE
- The current state cannot process the command. This refers to the state as returned by TransactionManager.getState(). The state should be retrieved, and the proper steps taken to enter the desired state.
static constexpr int32_t INVALID_CONFIGURATION
- Returned when the internal configuration of the SDK is invalid. This should generally be resolved during development, and should not occur in production. This command cannot be retried, the configuration should be fixed before proceeding.
static constexpr int32_t INVALID_ARGUMENTS
- Returned when the command is missing some required field. This should generally be resolved during development, though it might occur in production when moving to a different region without testing.
static constexpr int32_t COMMAND_IN_PROGRESS
- Command is already in progress. For example, when a payment is currently in progress and another payment is started. The current payment must be completed before another payment can be started. This can occur for other similar commands as well.
static constexpr int32_t UNSUPPORTED_COMMAND
- Invalid command. Occurs when the current device does not support the requested command. Please use the isCapable() methods to determine if the action can be performed before calling the API to avoid this error.
static constexpr int32_t COMMAND_TIMED_OUT
- A response was not received from the terminal in time. If this happens during a payment, querying the last transaction status can help recover. For most other operations, the command can simply be reissued.
static constexpr int32_t CONFIGURATION_REQUIRED
- The SDK requires configuration, generally because no devices have been paired. This generally happens during the first time the app is being used, and will not happen on subsequent launches, unless the persistent app data is lost. Please use the DisplayConfiguration method when this is encountered.
static constexpr int32_t MISSING_LISTENER
- Missing listener. Please attach a listener to perform any actions.
static constexpr int32_t RECEIPT_SUPPORT_REQUIRED
- Must Support Receipt Printing. TODO: Indicate if the POS that it can handle the receipt
static constexpr int32_t CACHED_CONFIGURATION_MISMATCH
- A device is configured but could not recognize using the known parameters. POS needs to clear the cache and retry the connection.
