Assets API: Unable to Create Content Fragment via post request.

[spidey1405]

I am trying to create content fragment using Assets API via POST request. Here's how my JSON looks like:

{

"class": [

"assets/asset"

],

"properties": {

"description": "Content Cateogry: Mutation-Example-02",

"title": "Mutation-Example-02",

"contentFragment": true,

"createdBy": "shivam_sahil@optum.com",

"elementsOrder": [

"title",

"uri"

],

"elements": {

"title": {

"variationsOrder": [],

"translatable": true,

":type": "string",

"variations": {},

"dataType": "string",

"title": "Title",

"multiValue": false,

"value": "Mutation Example"

},

"uri": {

"variationsOrder": [],

"translatable": true,

":type": "string",

"variations": {},

"dataType": "string",

"title": "URI",

"multiValue": false,

"value": "health-resources/mutation-example-02"

}

},

"name": "Mutation-Example-02"

}

}

Endpoint:

https://<HOST>/api/assets/<LOCATION>/mutation-example-02.json

However this fails with 500 internal server error. Can someone tell me the right structure of JSON?

I am having content fragment model category as shown below:

title: string (Text Field)

uri: string (Text Field)

Hi @spidey1405,

In general, it looks some information are missing in your JSON, e.g. cq:model property which is mandatory. Please have a look under below documentation:

• AEM Assets API in context of CF - https://experienceleague.adobe.com/docs/experience-manager-65/assets/extending/assets-api-content-fr...
• CF Swagger that shows structure of JSON for all endpoints - https://developer.adobe.com/experience-manager/reference-materials/6-5/assets-api-content-fragments/...

According to above, this is how correct JSON structure looks like for CF creation:

{
  "properties": {
    "cq:model": "/conf/path/to/model",
    "title": "string",
    "description": "string",
    "metadata": {
      "additionalProp1": "string",
      "additionalProp2": "string",
      "additionalProp3": "string"
    },
    "elements": {
      "{element1Name}": {
        "value": "<p>The HTML content of the element.</p>",
        ":type": "text/html",
        "variations": {
          "{variation1Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{variation2Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{elementNName}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          }
        }
      },
      "{element2Name}": {
        "value": "<p>The HTML content of the element.</p>",
        ":type": "text/html",
        "variations": {
          "{variation1Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{variation2Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{elementNName}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          }
        }
      },
      "{elementNName}": {
        "value": "<p>The HTML content of the element.</p>",
        ":type": "text/html",
        "variations": {
          "{variation1Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{variation2Name}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          },
          "{elementNName}": {
            "value": "<p>The HTML content of the element.</p>",
            ":type": "text/html"
          }
        }
      }
    }
  }
