Open APIs

Hi All,
What API would be used to get customer's product inventory from a CRM? I believe it would be TMF637 Product Inventory? Looking at the API Specification, there is 
List products - Which is to get all the products from the inventory and we can specify which fields we are interested .
Retrieve product - To get the detail about a product from the inventory using Product.id as input.

How do we get list of products that the customer has against his Billing Account for example?

HI Saravana
First, let me relate to your question - there is no guarantee that the product inventory will come from a CRM system. The TMF Open APIs do not make any assumptions about implementation or deployment architecture.
You are correct, you would use TMF637.
To understand which products are paid for by a particular billing account, you would need to use the list operation (GET without ID), and provide an appropriate filter expression to find the products whose productPrices are charged to the billing account. Something like an inclusive join between
billingAccount.id=<billingaccountID>
productPrice.billingAccount.id=<billingaccountID>

Of course, you need to ensure that your implementation will support this filter.
A json path filter might also be used, if your implementation supports that, refer to the design guidelines TMF630 for more details.

Hope it helps

Thanks Jonathan. This is useful as always. Just another query, how do I filter with relatedParty.id where @referredType is Individual? Given relatedParty is a list it can have many objects representing organization or individual.

Hi Saravana
Thanks for the compliment :)
I'm not sure I understand the problem - if you have the ID of the related party (or related party role) you would just use this in the query params, something like
filter="relatedParty.id==<theID>"
The fact that a product has a list of related parties does not make a difference.
If it is important to you the role being played by the party, you could add a join such as relatedParty.role=<role> (e.g. customer).
