Single or Batch Delivery

The Adobe Target Delivery API supports a single or batch delivery call. One can make a server request for content for single or multiple mboxes.

Weigh performance costs when deciding to make a single call versus a batched call. If you know all the content that needs to be shown for a user, the best practice is to retrieve content for all mboxes with a single batch delivery call, in order to avoid making multiple single delivery calls.

Single Delivery Call

You can retrieve an experience to display to the user for one mbox via the Adobe Target Delivery API. Note that if you are making a single delivery call, you would need to initiate another server call to retrieve additional content for an mbox for a user. This can become very costly over time, so please make sure to evaluate your approach when using the single Delivery API call.

  },
  "context": {
    "channel": "web",
    "browser" : {
      "host" : "demo"
    },
    "address" : {
      "url" : "http://demo.dev.tt-demo.com/demo/store/index.html"
    },
    "screen" : {

    }
  },
    "execute": {

      {
        "name" : "SummerOffer",
        "index" : 1
      }
    ]
  }
}'

In the single delivery call example above, the experience is retrieved to display to the user with tntId: abcdefghijkl00023.1_1 for an mbox:SummerOffer on the web channel. This single delivery call will generate the following response:

{
  "status": 200,
  "requestId": "25e0cc42-3d7b-456a-8b49-af60c1fb23d9",
  "client": "demo",
  "id": {
      "tntId": "abcdefghijkl00023.1_1"
  },
  "edgeHost": "mboxedge28.tt.omtrdc.net",
  "execute": {
      "mboxes": [
          {
              "index": 1,
              "name": "SummerOffer",
              "options": [
                  {
                      "content": "<p><b>Enjoy this 15% discount on your next purchase</b></p>",
                      "type": "html",
                  }
              ]
          }
      ]
    }
}

In the response, note the content field contains the HTML that describes the experience to be shown to the user for the web that corresponds to the SummerOffer mbox.

Execute Page Load

If there are experiences that should be shown when a page load happens in the web channel, such as AB testing the fonts located in the footer or header, you can specify pageLoad in the execute field to retrieve all modifications that should be applied.

curl -X POST \
  'https://demo.tt.omtrdc.net/rest/v1/delivery?client=demo&sessionId=d359570e04f14e1faeeba02d6ab9914e' \
  -H 'Content-Type: application/json' \
  -H 'cache-control: no-cache' \
  -d '{
  "id": {
    "tntId": "84e8d0e211054f18af365d65f45e902b.28_131"
  },
  "context": {
    "channel": "web",
    "window": {
      "width": 1819,
      "height": 842
    },
    "browser": {
      "host": "target.enablementadobe.com"
    },
    "address": {
      "url": "https://target.enablementadobe.com/react/demo/#/"
    }
  },
  "execute": {
    "pageLoad": {}
  }
}'

The sample call above retrieves any experiences to show a user when the page https://target.enablementadobe.com/react/demo/#/ loads.

{
      "status": 200,
      "requestId": "355ebc47-edb6-481f-aeae-ae55d71afaca",
      "client": "demo",
      "id": {
          "tntId": "84e8d0e211054f18af365d65f45e902b.28_131"
      },
      "edgeHost": "mboxedge28.tt.omtrdc.net",
      "execute": {
          "pageLoad": {
              "options": [
                  {
                      "content": [
                          {
                              "type": "setHtml",
                              "selector": "#app > DIV:nth-of-type(1) > DIV:nth-of-type(1) > NAV.nav:eq(0) > DIV.container:eq(0) > DIV.nav-right:eq(0) > A.nav-item:eq(0)",
                              "cssSelector": "#app > DIV:nth-of-type(1) > DIV:nth-of-type(1) > NAV:nth-of-type(1) > DIV:nth-of-type(1) > DIV:nth-of-type(2) > A:nth-of-type(1)",
                              "content": "Modified Home"
                          }
                      ],
                      "type": "actions"
                  }
              ],
              "metrics": [
                  {
                      "type": "click",
                      "selector": "#app > DIV:nth-of-type(1) > DIV:nth-of-type(2) > SECTION.section:eq(0) > DIV.container:eq(0) > FORM.col-md-4:eq(0) > DIV.form-group:eq(0) > BUTTON.btn:eq(0)",
                      "eventToken": "QPaLjCeI9qKCBUylkRQKBg=="
                  }
              ]
          }
      }
  }

In the content field, the modification that needs to be applied on a page load can be retrieved. In the example above, note that a link on the header needs to be named Modified Home.
