## Okta integration
- https://developer.okta.com/docs/guides/scim-provisioning-integration-prepare/main/
Sample provisioning settings that work. Capabilities can be disabled and attributes can be removed as needed.
![Okta to Fleet provisioning](./assets/SCIM-Okta-provisioning.png)
From our testing with Okta, we see the following behavior that is worth noting:
- Okta does not use PATCH endpoint
- Okta does not DELETE users; if a new user needs to be created with the same username as a "deleted" user, then it overwrites the old user
### Automated test for Okta integration
First, create at least one SCIM user:
```
POST https://localhost:8080/api/latest/fleet/scim/Users
Authorization: Bearer <API key>
{
"schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
"userName": "test.user@okta.local",
"name": {
"givenName": "Test",
"familyName": "User"
},
"emails": [{
"primary": true,
"value": "test.user@okta.local",
"type": "work"
}],
"active": true
}
```
Run test using [Runscope](https://www.runscope.com/). See [instructions](https://developer.okta.com/docs/guides/scim-provisioning-integration-prepare/main/#test-your-scim-api).
## Entra ID integration
- [SCIM guide](https://learn.microsoft.com/en-us/entra/identity/app-provisioning/use-scim-to-provision-users-and-groups)
- [SCIM validator](https://scimvalidator.microsoft.com/)
- Only test attributes that we implemented
### Testing Entra ID integration
Use [scimvalidator.microsoft.com](https://scimvalidator.microsoft.com/). Only test the attributes that we have implemented. To see our supported attributes, check the schema:
```
GET https://localhost:8080/api/latest/fleet/scim/Schemas
```
## Authentication
We use same authentication as API. HTTP header: `Authorization: Bearer xyz`
