# Method name: updatePlan(planInfo: UpdatePlanInfo)

# Method package: wixPricingPlansBackend

# Method menu location: wixPricingPlansBackend --> updatePlan

# Method Link: https://dev.wix.com/docs/velo/apis/wix-pricing-plans-backend/update-plan.md

# Method Description:

Updates a pricing plan.

The `updatePlan()` function returns a Promise that resolves to an updated plan. 

 Updating a plan does not impact existing purchases made for the plan. All purchases keep the details of the original plan 
 that was active at the time of purchase.

 Only users with "Manage Pricing Plans" [permissions](https://support.wix.com/en/article/roles-permissions-accessing-roles-permissions) can update plans.



# Method Code Examples:

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