# Method name: updatePolicy(_id: string, policy: UpdatePolicy, options: UpdatePolicyOptions)

# Method package: wixEventsV2

# Method menu location: wixEventsV2 --> policies --> updatePolicy

# Method Link: https://dev.wix.com/docs/velo/apis/wix-events-v2/policies/update-policy.md

# Method Description:

Updates a policy.

<!--
> Note: This function is restricted and only runs if you elevate permissions using the [wix-auth.elevate()](https://www.wix.com/velo/reference/wix-auth/elevate) function.
-->

The `updatePolicy()` function returns a Promise that resolves to the newly-updated policy.

Each time the policy is updated, `revision` increments by 1. The existing `revision` must be included when updating the policy. This ensures you're working with the latest policy and prevents unintended overwrites.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Update Policy (dashboard page code)

```javascript
import { policies } from 'wix-events.v2';

// define policy ID and policy object to update
const id = '52f15c5c-ea06-44f4-866a-b1cfa6f4f790';
const policy = {
   name: 'Terms and Conditions Event 1',
   body: 'If the Event is rescheduled, changed, moved or cancelled the Organiser cannot be held responsible for any resulting costs you may incur for travel, accommodation and other related goods, services or compensation.',
   revision: '2',
   eventId: '3d3d5c04-ece0-45a8-85f0-11a58edaa192'
 };

// update policy
async function elevatedUpdatePolicyFunction(){
  const elevatedUpdatePolicy = wixAuth.elevate(policies.updatePolicy);
   try {
     const result = await elevatedUpdatePolicy(id, policy);
     return result;
   } 
   catch (error) {
     console.error(error);
     // Handle the error
   }
 };

/* Returns a promise that resolves to
   the updated policy.

## Update Policy (export from backend code)

```javascript
import { Permissions, webMethod } from 'wix-web-module';
import { policies } from 'wix-events.v2';
import { elevate } from 'wix-auth';

// define policy ID and policy object to update
const id = '52f15c5c-ea06-44f4-866a-b1cfa6f4f790';
const policy = {
   name: 'Terms and Conditions Event 1',
   body: 'If the Event is rescheduled, changed, moved or cancelled the Organiser cannot be held responsible for any resulting costs you may incur for travel, accommodation and other related goods, services or compensation.',
   revision: '2',
   eventId: '3d3d5c04-ece0-45a8-85f0-11a58edaa192'
 };

// update policy
export const elevatedUpdatePolicyFunction = webMethod(Permissions.Anyone, async () => {
  const elevatedUpdatePolicy = elevate(policies.updatePolicy);
   try {
     const result = await elevatedUpdatePolicy(id, policy);
     return result;
   } 
   catch (error) {
     console.error(error);
     // Handle the error
   }
 });
