Onboard DAM to CMS (SaaS)

At present, you must contact Support to integrate DAM in CMS (SaaS) and grant access to an experimental preview 3 of the API. There are three types available for the DAM integration and these need to configured accordingly in a request to the API.

Type	Key	Source Key	Source Type	Base Type
Images	DamImageSource	cmp	cmp_PublicImageAsset	image
Videos	DamVideoSource	cmp	cmp_PublicVideoAsset	video
Files	DamRawFileAsset	cmp	cmp_PublicRawAsset	media

Replace the parameters key, sourceKey, sourceType and contentBaseType with the values in the previous table. The remainder of the request should remain intact.

📘
Note
This step is temporary and the CMS API in preview3 is experimental and is subject to change. Go to Settings > API Keys to create the credentials used to interact with the API. Create a key for this purpose and use the Client Id and Secret when authenticating.

Authenticate

curl --location '{{host}}/\_cms/preview3/oauth/token'  
--header 'Content-Type: application/json'  
--data  '  
{  
   "grant_type": "client_credentials",  
   "client_id": "{{clientid}}",  
   "client_secret": "{{clientsecret}}"  
}'

Create Content Source

curl --location '{{host}}/\_cms/preview3/experimental/contentsources'  
--header 'Content-Type: application/merge-patch+json'  
--header 'Authorization: Bearer {{your_access_token}}'  
--data '  
{  
      "key": "DamImageSource",  
      "displayName": "DAM Image",  
      "sourceKey": "cmp",  
      "sourceType": "cmp_PublicImageAsset",  
      "type": "graph",  
      "guidIdFormat": "digits",  
      "propertyMappings":[  
        {  
            "cmsKey": "Id",  
            "sourceKey": "Id"  
        },  
        {  
            "cmsKey": "Name",  
            "sourceKey": "Title"  
        },  
        {  
            "cmsKey": "Url",  
            "sourceKey": "Url"  
        }  
      ],  
      "contentBaseType": "image"  
}'

Delivery to the frontend

Optimizely Graph is the delivery channel for content in CMS SaaS and this is also true for DAM assets. Content is indexed into Optimizely Graph including the reference of the DAM assets identity. Optimizely Graph queries for CMS content include the DAM asset with its data in a shared result. You do not need additional lookups to retrieve DAM data because the data is included in the response.

Query example of CMS and DAM content

In Optimizely Graph, the following code shows how to query an Examplecontent type page that has three ContentReference properties, MainImage, Video and Pdf and return a joint result of CMS and DAM data. In the example is Video and Pdf ordinary ContentReference properties without item type specified. The ContentReference property MainImage on the other hand has item type specified as 'cmp_PublicImageAsset' and therefore that does not need to be projected/casted in query.

query PageWithAssetsQuery {
  Example(
    where: { _metadata: { key: { eq: "303ddcad1b7c4895a730abbb0730a677" } } }
  ) {
    items {
      _id
      Title
      MainImage {
        url {
          graph
        }
        item {
           Id
           Url
           Title
        }
      }
      Video {
        item {
          ... on cmp_PublicVideoAsset {
            Id
            Url
            Title
          }
        }
      }
      Pdf {
        item {
          ... on cmp_PublicRawFileAsset {
            Id
            Url
            Title
          }
        }
