# 11.2. BLIK in the sandbox environment.

To test BLIK transactions, use the following data.

| Code         | Behavior                                      |
|---------------|-----------------------------------------------|
| 777000       | Completed                                     |

# Testing asynchronous errors
      The Axepta API enables you to test Blik payments by simulating asynchronous errors through the use of the amount, title, and blikCode parameters.

# Throwing asynchronous errors using `blikCode`
      Here’s a table representation of the provided Blik codes and their statuses:

| blikCode  | Status                            | Status Code          |
|-----------|-----------------------------------|----------------------|
| 999000    | SETTLED    |                      |
| 912111    | REJECTED   | ALIAS_DECLINED       |
| 927111    | REJECTED   | TAS_DECLINED         |
| 934111    | REJECTED   | USER_DECLINED        |
| 969111    | REJECTED   | SEC_DECLINED         |
| 956111    | REJECTED   | SYSTEM_ERROR         |
| 961111    | REJECTED   | GENERAL_ERROR        |
| 960111    | REJECTED   | INSUFFICIENT_FUNDS   |

| 949111    | REJECTED   | USER_TIMEOUT         |
| 902111    | REJECTED   | ISSUER_DECLINED      |

- Important note!

>Despite the transaction status being set to "Rejected", an additional asynchronous notification is sent at the end of the transaction process. This notification includes the relevant `StatusCode`.

#Throwing asynchronous errors using `amount`
    Here’s a table representation of the provided amount values and their statuses. 
    For testing errors with amounts, you should use the blikCode: 777 xxx (where xxx can be any digits).

| amount | Status                          | Status Code          |
|-----------|---------------------------------|----------------------|
| 28800     | REJECTED   | ALIAS_DECLINED       |
| 19200     | REJECTED   | TAS_DECLINED         |
| 14400     | REJECTED   | USER_DECLINED        |
| 21600     | REJECTED   | SEC_DECLINED         |
| 26400     | REJECTED   | SYSTEM_ERROR         |
| 36000     | REJECTED   | GENERAL_ERROR        |
| 12000     | REJECTED   | INSUFFICIENT_FUNDS   |
| 31200     | REJECTED   | TIMEOUT              |

| 16800     | REJECTED   | ISSUER_DECLINED      |

#Testing synchronous errors
    The Axepta API enables you to test Blik payments by simulating synchronous errors through the use of the blikCode value.

#Throwing synchronous errors using blikCode
     Here’s a table representation of the provided blikCode values and transaction statuses:
    
| blikCode | Status                          | Status Code          |
|-----------|---------------------------------|----------------------|
| 123444    | REJECTED    | ER_WRONG_TICKET                     |
