import { items } from '@wix/data';

async function removeReference(dataCollectionId,field,referringItem,referencedItem,options) {
  const response = await items.removeReference(dataCollectionId,field,referringItem,referencedItem,options);
};
```

### removeReference (with elevated permissions)
```javascript
import { items } from '@wix/data';
import { auth } from '@wix/essentials';

async function myRemoveReferenceMethod(dataCollectionId,field,referringItem,referencedItem,options) {
  const elevatedRemoveReference = auth.elevate(items.removeReference);

```javascript
import { createClient } from '@wix/sdk';
import { items } from '@wix/data';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { items },
  // Include the auth strategy and host as relevant
});


async function removeReference(dataCollectionId,field,referringItem,referencedItem,options) {
  const response = await myWixClient.items.removeReference(dataCollectionId,field,referringItem,referencedItem,options);
};
```
