# Partners

## Partner Code: <a href="#partner-sandbox-partnercode" id="partner-sandbox-partnercode"></a>

Please note that each partner will be assigned a three-letter word by Merrco Payfirma (please ask us if you require one).

To tag all transactions originating from your application, please send your assigned three-letter word

in the custom\_id field in the sales request packet. This identifying word will help us to reconcile all data for

merchants using your application.

### Test Case: <a href="#partner-sandbox-testprocessor" id="partner-sandbox-testprocessor"></a>

The Test Processor is a simulated processor designed for testing purposes, featuring placeholder processing logic. Specific outcomes are triggered based on the following conditions:

1. All transactions with an odd amount (digits before decimals) will be approved.
2. All transactions with an even amount (digits before decimals) will be declined.
3. Refunds exceeding the actual sale amount will be declined.
4. Captures with an even amount will also be declined.

Special Cases:

* $2.10 will result in a decline with the reason "Failed to tokenize card information."
* $2.20 will result in a decline with the reason "Email is required."
* $2.30 will result in a decline with the reason "Missing mandatory card information field(s) in the request."
* $2.40 will result in a decline with the reason "Transaction Not Supported."
* $2.50 will result in a decline with the reason "Failed to de-tokenize card information."
* $2.60 will result in a decline with the reason "Failed to authorize."
