Adobe Target Recommendations using Server Side Delivery

Hi Team,

 

We are planning to use Adobe Target Recommendations using Server Side.

I am referring the help doc developer.adobe.com/target/before-administer/recs-api/fetch-recs-server-side-delivery-api/ to implement this. I need to check the json response of the recommendation activity

I have already defined the json design (non html) and form based recs activity using Adobe Target . I am facing issue with API body so wanted to check the exact structure (it is not clear in the help doc)

 

Any pointers  in this regard will be really helpful.

Hi @ambikatewari_atci 

It looks like your delivery api mbox response is coming through without issue (and you are able to see the mbox trace).

The response code NO_CONTENT indicates the issue most likely lies with your Recommendations Criteria.

 

I would review your criteria and maybe use a basic one like "most popular" (and enable backup recommendations) as a starting point and remove any inclusion/exclusion rules.

You might also want to review the Global Exclusions, I can see there are a bunch defined in your Mbox Trace that could be stopping you getting any Recommendations back.

 

There are some common causes documented here:

Hello @ambikatewari_atci,
maybe this will help you from the API documentation to validate your design?

Hi @ambikatewari_atci 

 

Assuming you have created a Recommendations Activity with the form based composer that returns a JSON recommendations design as outlined on that page.

 

Is your issue related to formatting the body of the /delivery API call? (in JSON format)

This page contains some good examples:

Thank you @jacobto1  @perrin_ennen  thank you for your response.

 

I have used this request body alongwith trace:

{
    "id": {
        "tntId": "fa7a61803b44410a80d412fe47646090.31_0"
    },
    "context": {
        "channel": "web",
        "address": {
            "url": "https://www.abc.com/default"
        },
        "screen": {
            "width": 1536,
            "height": 864
        }
    },
     "property" : {
        "token": "c72849c6-2a3c-8a3b-xx00-12345baf1234"
      },
    "trace": {
        "authorizationToken": "685dfad4-951b-4d93-a5dc-e9a6af26327a"
    },
    "execute": {
        "mboxes": 
        [
            {
            "name": "recommendationMbox",
            "index": 1
        }
        ]
    }
}

but getting no recommended entities under the option but got this :

does it mean system doesnt have any entities to recommend thats why it showed this ?
 
Baically I need json response for the recommendation delivery API and entity mbox are still not implemented on the category and entities pages. 
Can I still expect my recommendation activity to return the items ?
