| Error code | `transaction_requires_currency_code_for_custom_discount` |
| Error message | Cannot create transaction without currency code |

## Common causes

- Transaction requires a `currency_code` when a custom `discount` of `type` `flat` or `per_seat` is set.

## Common solutions

- Include a `currency_code` in the transaction payload.
- Update the `type` for the `discount` to `percentage`.
