With Control Center, you can initially map a transaction type only with one processing code, but you can add more later. When you create a new transaction type, Control Center automatically creates a corresponding reversal processing code and transaction type for you.

Create a processing code

To create a processing code:

1. From the main menu, select Configurations > Processing codes & transaction types.
   The Processing codes & transaction types screen displays with the Processing codes tab open by default.
2. On the Processing codes & transaction types screen, select Create.
3. On the Processing code tab, enter a unique Processing code name and an ID using 1–6 letters and numbers.
4. Select the type of balance impact for the transaction. Balance impact indicates how a transaction affects an account: it can credit funds, debit funds, or have no impact, known as Zero balance.
5. Optionally, select the appropriate tags to identify related processing codes.
6. Select Next.
7. On the Reversal processing code tab, select either Create new or Select existing.
   1. If you chose Create new:
      1. Enter a unique Reversal processing code name or leave the default.
      2. Define a Reversal processing code ID using 1–6 letters and numbers.
   2. If you chose Select existing, choose the Select button next to the existing Reversal processing code you want to add.
8. In the Partial reversal processing code section, you will select or create a partial reversal processing code. This code is used to cancel or reverse part of a previously authorized transaction. It releases a portion of the funds. For example, it adjusts the payment amount when a customer returns part of an order.
   Select Use default, Create new, or Select existing.
   1. If you chose Create new:
      1. Enter a unique Partial reversal processing code name or leave the default.
      2. Define a Partial reversal processing code ID using 1–6 letters and numbers.
      3. Select Next.
   2. If you chose Select existing:
      1. Choose the Select button next to the existing Partial reversal processing code you want to add.
      2. Select Next.
   3. If you chose Use default, select Next.
9. On the Review tab, verify that the information you provided is correct and select Finish.
   The Processing codes details screen for the processing code you just created is displayed.
10. Since no transaction types have been created yet for this processing code, its status on the Authorization PC tab will be Missing TT. To add a transaction type, select the Add transaction type button at the bottom of the screen.

For details on adding a transaction type to your new processing code, follow the instructions in the Add a transaction type to an existing processing code guide.

To create a processing code using the APIs, use the Create processing code endpoint.

Processing codes details

When you select a processing code from the list on the Processing codes tab, its details are displayed on the Processing codes details screen. This screen has three tabs and open by default to the Authorization PC tab.

• Authorization PC tab—Displays a list of all authorization processing codes associated with the selected code.
• Reversal PC tab—Displays a list of only reversal processing codes associated with the selected code.
• Partial reversal PC tab—Displays a list of only partial reversal processing codes associated with the selected code.

To edit a processing code name, select the Edit icon to the right of the name on its details screen then make the desired change and select Save.
