How to place an order from REST Api

[wakespirit]

Dear all,

I have a need to place an order from REST Api through an external application in ServiceNow

For that I have seen we need to use the service catalog Api and undertand that we need to :

- collect items from a given category
- place item in a cart using dedicated api

All those steps are ok and clear.

Now at some point there is the need to validate the order based on given cart items collection.
For that I have seen there are different API where I am confused on which to use :

- Check out Cart
- Submit Order

Which one to use in order that ServiceNOw generate in background the ServiceCatalog Task and Request Item ?

How to handle order if it is need to go through a Record Producer instead of getting individual items ?

Thanks for help

regards

Hi

Submission of the cart via the REST API depends on the two step checkout parameter. 

Please refer to the documentation on API and two step checkout.

Thanks for your reply

By the way if I am using one step checkout to be simple, when I am submitting my cart, how do I know that

I am submitting the correct cart as I can have different ongoing cart ?

Thanks for your reply

By default,  logged in user's cart is used to submit the order. All the items added to the default cart are going to be submitted.

In case, if you have a requirement to submit the cart of multiple users. You may retrieve the default cart of the user with Gliderecord on sc_cart table and submit the order of each user cart
