## parametersToMedicationCheckoutResponse() function

Decodes the `Parameters` response from the `$checkout-medications` custom operation into a typed [MedicationCheckoutResponse](/content/docs/sdk/core.medicationcheckoutresponse). Throws `INVALID_MEDICATION_CHECKOUT_RESPONSE` when required top-level fields are missing.

The repeating `items` parameter is collected across every occurrence (each is one queued/failed line); the scalar `approvalUrl` / `vendorPatientId` are read once.

**Signature:**

```typescript
export declare function parametersToMedicationCheckoutResponse(params: Parameters): MedicationCheckoutResponse;
```
