Postman Sample Request - Create API

Hi,

Is there any sample code available for calling the create API [POST /data/:ledgerId/v1/create] using Postman?

I am trying to call the CreateQuoteRequest choice from the BuyerRole and need some help.

Stripped out Workflow
Operator -> Create Network
Operator -> ExerciseCmd BuyerInvitation on Network - Buyer1
Operator -> ExerciseCmd SellerInvitation on Network- Seller1
Operator -> ExerciseCmd CreateProductCard on Network- PID : 100
Buyer1 -> AcceptBuyerInvitation
Seller1 -> AcceptSellerInvitation
Buyer1 -> ExerciseCmd CreateQuoteRequest with quoteInfos [PID:100, Seller 1]
Seller1 -> Accept QuoteRequest
Buyer1 -> AcceptQuote

(below is stripped out model)

Hi @Arvind_Rao. I’m not aware of any examples, but I have seen people use Postman to interact with the API so I know it works. What have you tried so far? Are you experiencing any errors?

Thanks, no worries figured it out (looking at the documentation)

Team was running into issues in calling the APIs’ directly, so wanted to see the bare request/response so they would implement that in their reactjs code.
