Learning objective

Send a simulated Order Shipped event to trigger the journey using Postman

Streaming to Hub vs Edge

Earlier, we sent in an Event to the Edge. There are some use cases where we may have a back-end system that wants to stream in an event, but does not need to send it to the Edge. This lab shows how to do that by streaming in an Order Shipped event to the Hub (aka server to server, e.g. Commerce Server to AEP signaling an order has shipped).

Validate event is not in Profile

  1. Go over to your Profiles and lookup the Profile.

    • Identity namespace -> email
    • Identity value -> henry.creel@emailsim.io

  2. Click on Events tab.

    • There should be no orders.shipped events

Modify API request

To create the API request, you need to fill in the following pieces in the body of the API request.

Start by gathering the following values:

Find account streaming endpoint

  1. Navigate to Sources in the left rail and then click on Accounts in the top nav
  2. Search for dep: HTTP API [raw], highlight the row and copy and save the value of the Streaming Endpoint somewhere you can reference later

dep: HTTP API raw account row highlighted with Streaming Endpoint value

Find dataflow ID

  1. Click on dep: HTTP API [raw]
  2. Find the record for dep: Orders (stream) click on the dataflows link
  3. In the right rail copy and save the Dataflow ID values somewhere you can reference later
WARNING
Click in an empty space on the row. DO NOT click on the blue links!

Open Postman

Launch Postman on your computer and navigate to the following API call:

  • Postman Left Sidebar --> Collections
  • Collection --> AJO Bootcamp (Labs)
  • Folder --> Profile & Journey Labs
  • API Request --> Ship Order Event

Create final API request

  1. Copy the values you saved in the previous steps into the places highlighted below.

  2. Click on Headers and paste in these values (remove any trailing spaces):

    • Red --> Streaming Endpoint URL
    • Green --> Dataflow ID
      • Value looks like a GUID (does not start with http)
CAUTION
DO NOT EXECUTE YET!
