Requesting banner ads

Requesting ads

As product ads and banners are generated on the same endpoint, if your placement's context is the same, you are able to request product ads in the same request as banners.

The number of products ads you may receive is configured by defining the maxNumberOfAds parameter. The number of banner ads you may receive can be configured with the maxNumberOfAds property per unique slotId

All banner ad requests require the contentStandardId and the bannerSlots you are requesting ads for. In addition, your banner call should include the context's customerId,sessionId,placement, and catalogId.

📘

You might notice some changes here!

We're introducing a change to how you request banner ads from CitrusAd. If you are already integrated, you might request with a property called bannerSlotIds. We've superseded this with our new bannerSlots capability. If you'd like to review how to request ads with the bannerSlotIds property, please navigate to the bottom of this page.

This bannerSlots capability was rolled out in September, 2022.

Search placements

Search placements are typically the easiest to request. They require a searchTerm to be specified in the request, like the example below:

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "search",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "searchTerm": "chocolate",
    "options": {
   						 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ],           
    "maxNumberOfAds": 3    
}

Category placements

Category placements require productFilters to be specified in the request. Below is an example of where you would send the category filters:

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "category",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "productFilters": [
     	 ["category:Cupboard/Snacks"]
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ],            
    "maxNumberOfAds": 3
}

As additional categories are perused, you should update your API call accordingly.

Cross-sell category placements

Cross-sell category placements have a very similar request to category placements. You will want to specify the exact category you are requesting ads for. This is typically the page you are on. Specify the category in the productFilters of the request. The example below shows where you would send the category filters:

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "category-cross-sell",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "productFilters": [
     	 ["category:Cupboard/Snacks"]
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ],            
    "maxNumberOfAds": 3
}

As additional categories are perused, you need to update your API call accordingly.

Merging organic and cross-sell category targeting?

If you're looking to merge an organic and cross-sell category ad request into a single placement, you will need to implement merging and delivery logic to your customers. This is the integator's responsibility, though CitrusAd are happy to be consulted.

In general, we advise that you show organic category ads, and position and category cross-sell advertisements after the organic placements.

Broad match placements

Broad placements such as home or checkout pages do not require any productFilters to be specified in the request. Any filters the retailer would like to specify (on offer, new, etc) can be specified in the productFilters to ensure CitrusAd only serve ads within the requirements, like the example below:

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "home",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "productFilters": [
     	 []
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ], 
    "maxNumberOfAds": 3
}

Request enhancements

We advise you to consider the below enhancements to improve your user experience.

Filtered searches

If your customer filters their search, you can extend your context to provide productFilters. Below is an example where the customer is filtering by the category "Cupboard" and the dietary restriction "Gluten-free". This same principle can be applied to any category or broad match placement.

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "search",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "searchTerm": "chocolate",
    "productFilters": [
     	 ["category:Cupboard"],["dietary:Gluten-free"]
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ], 
    "maxNumberOfAds": 3
}

Filtering by location

If you are synchronising location filters in your catalog, you can extend your context to provide the customer's store location in the productFilters, like the example below:

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "search",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "searchTerm": "chocolate",
    "productFilters": [
     	 ["category:Cupboard"],["dietary:Gluten-free"],["location:Westenbury"]
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlots": [
           {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 1
    },
    {
      "slotId": "<SLOT_ID>",
      "maxNumberOfAds": 2
    }
    ], 
    "maxNumberOfAds": 3
}

Using the bannerSlotIds parameter (legacy)

If you're already integrated, you might be requesting ads with bannerSlotIds instead of bannerSlots. This is an array of strings wherein you would specify the banner slots you require ads for. We've improved our capability so that you can request more than one ad for the same banner slot. If you are interested, you will need to enhance your integration to the bannerSlots method outlined above.

POST $BASE_URL/v1/ads/generate HTTP/1.1
accept: application/json
content-type: application/json
Authorization: Basic <API_KEY>
{
    "customerId": "wertg5432a",
    "sessionId": "ec9-4e07-881d-3e9",
    "dtmCookieId": "AAAF8xLBTA968AB6TOthAAAAAAE",
    "placement": "search",
    "catalogId": "628dbe95-2ec9-4e07-881d-3e9f92ab2e0b",
    "searchTerm": "chocolate",
    "productFilters": [
     	 ["category:Cupboard"],["dietary:Gluten-free"],["location:Westenbury"]
    ],
    "options": {
   							 "filterMode": "AndOr"
 							 },
    "contentStandardId": "fec2ab89-7a29-42b5-b58a-5675688b52d9",
    "bannerSlotIds": [
        "<SLOT_ID>","<SLOT_ID>"
    ], 
    "maxNumberOfAds": 3
}

The banner ad response

All responses follow the same JSON format. If you are requesting product ads, the ads array will be populated as per the example below. Banners populate the banners array, so content is only returned for banner slots with ads.

The id field is your Ad ID used in impression and click reports. Please refer to the reference for more information on each string.

Marketplace sellerId

If onboarding marketplace sellers, you may see an additional sellerId per ad in the response. This will only appear if the team that owns the campaign being served has a seller ID configured in the UI. The example below shows one ad with a sellerId, one without.

CitrusAd support the tracking tags below:

  • DoubleVerify
  • DCM Click
  • DCM Impression
  • IAS

If a campaign has a tracking tag configured, it will present as the relevant field in the tags object below. Please note, if a campaign does not have a tag configured, the tags object will remain empty.
