### updateTier (self-hosted)
Self-hosted SDK calls require you to [create a client](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-the-wix-client.md).

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

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


async function updateTier(_id,tier) {
  const response = await myWixClient.tiers.updateTier(_id,tier);
};
```
