Magento 2 Create an order using Integration token in REST API

Question

I want to place orders on behalf of a customer. I have an integration token for this. I have followed the below steps.

Create Empty Cart = POST /V1/carts (Passing customer Id as param)
Add product to cart = POST "/V1/carts/".$quote_id."/items" (Passing product data)
Get Shipping methods = POST "/V1/carts/".$quote_id."/estimate-shipping-methods"
Set shipping and billing = POST "V1/carts/".$quote_id."/shipping-information"

The above steps are working fine. Now I need to set the payment method and place the order. How can I do it?

Create Empty Cart: /V1/carts/mine => POST with payload {'customer_id':{customerId}}. It returns the cartId
Add Products to cart: /V1/carts/{cartId}/items => POST Request
Get Cart Totals: /V1/carts/{cartId}/totals => GET Request
Estimate Shipping methods: /V1/carts/{cartId}/estimate-shipping-methods => POST Request ( It list all availble shipping methods)
Set Billing and Shipping: /V1/carts/{cartId}/shipping-information => POST Request (It returns the availble payment methods)
Set Payment and place order: /V1/carts/mine/payment-information => POST Request (It returns the Order increment Id)
To get the order Details: /V1/orders => GET Request with search criteria

searchCriteria[filter_groups][0][filters][0][field]=increment_id&searchCriteria[filter_groups][0][filters][0][value]={IncrementId}
