Hi Naga,
SCIM user schema does not have something like **birthday** or **gender** attrs, so it's not supported by default. If you want to add those, you will have to resort to using the schema extension. Suggested reading: [Creating your own attributes by using extensions](https://www.gluu.org/docs/ce/user-management/scim2/#creating-your-own-attributes-by-using-extensions).
Example of a POST payload for creating a user that includes custom attributes:
```
{
"schemas": [
"urn:ietf:params:scim:schemas:core:2.0:User",
"urn:ietf:params:scim:schemas:extension:gluu:2.0:User"
],
"urn:ietf:params:scim:schemas:extension:gluu:2.0:User": {
"scimCustomFirst": "String single-valued",
"scimCustomSecond": [
"2016-02-23T15:35:22Z"
],
"scimCustomThird": 3000
},
"userName": "scim_test_bjensen",
"name": {
"familyName":"Jensen",
"givenName":"Barbara",
"middleName":"Jane"
},
"displayName": "Brava",
"nickName": "Babas"
}
```
In your case, as **birthday** and **gender** already exist as LDAP attributes, you would just need to flag those as scim'd: in oxTrust go to `Configuration` > `Attributes`, click on **birthday**, and under "SCIM Attribute" choose `True`. The same goes for **gender**.
Regards,
Jose.
