Custom SCIM extension attributes not sent by ISC connector on CREATE

When creating an account through the ISC native SCIM connector, attributes declared under the “urn:ietf:params:scim:schemas:extension:custom:2.0:User” namespace are not included in the payload sent to the target API, despite:

- The extension schema being declared in the “schemas” array

- The attributes (“codeUni”, “codePar”) being defined in the source **Provisioning Policy**

- The target API expecting the following payload structure:

{

  "schemas": [

    "urn:ietf:params:scim:schemas:core:2.0:User",

    "urn:ietf:params:scim:schemas:extension:custom:2.0:User"

  ],

  "userName": "userName",

  "name": {

    "givenName": "givenName",

    "familyName": "familyName"

  },

  "emails": [

    {

      "value": "test@email.com",

      "type": "work",

      "primary": true

    }

  ],

  "urn:ietf:params:scim:schemas:extension:custom:2.0:User": {

    "codeUni": [{ "value": "LOK009"}],

    "codePar": [{ "value": "YOP006"}]

  }

}

The connector correctly sends **core** attributes (“userName”, “name”, “emails”) but **silently drops** the custom extension block, causing the target API to return “HTTP 400”.

Hey @FXNOAHOWONO you need to add Before provisioning rule
Provisioning of Extended Attributes{

In ISC, defining the custom extension URN and adding codeUni / codePar in the provisioning policy may not be enough if the target expects them under a nested SCIM extension object during CREATE. SailPoint’s SCIM extended-attributes guidance points to using a Before Provisioning rule to modify the provisioning plan for this kind of case.

Since your target expects:


"urn:ietf:params:scim:schemas:extension:custom:2.0:User": {
"codeUni": [{ "value": "LOK009" }],
"codePar": [{ "value": "YOP006" }]
}

I would read the flat values from the provisioning policy, remove them as standalone attributes, and then add a single attribute request for the extension block with the nested structure.

Also note that these are complex multi-valued attributes, so the exact array/object shape matters. If the native SCIM connector still doesn’t serialize the extension correctly on CREATE after that, I’d consider a Web Services source for full payload control.

as @raghav_chouda mentioned, a Provisioning rule should be written. Reference: Provisioning of Extended Attributes
