# Create adjustment

Adjustments allow you to directly impact the balance of an account outside of normal usage processing.

This might be necessary to reflect out-of-bound operations such as refunds, or if you operate a hybrid setup and collect funds outside of Credyt.

Every adjustment must have a corresponding `reason` that influences how revenue is ultimately recognized.

The adjustment `transaction_id` is used as an idempotency key to ensure safe retries.
