Implementing SCIM Provisioning with Okta

Overview

SCIM (System for Cross-domain Identity Management) is an open standard protocol (RFC 7644) that automates the exchange of user identity information between identity providers like Okta and service providers. This skill covers building a SCIM 2.0-compliant API endpoint and integrating it with Okta for automated user lifecycle management including provisioning, deprovisioning, profile updates, and group management.

When to Use

• When deploying or configuring implementing scim provisioning with okta capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

Prerequisites

• Okta tenant with admin access (Developer or Production)
• Application with REST API capable of user management
• TLS-secured endpoint (HTTPS required)
• Okta API token or OAuth 2.0 client credentials
• Python 3.9+ with Flask or FastAPI

Core Concepts

SCIM 2.0 Protocol

SCIM defines a standard schema for representing users and groups via JSON, with a RESTful API for CRUD operations:

Operation	HTTP Method	Endpoint	Description
Create User	POST	/scim/v2/Users	Provisions a new user account
Read User	GET	/scim/v2/Users/{id}	Retrieves user details
Update User	PUT/PATCH	/scim/v2/Users/{id}	Modifies user attributes
Delete User	DELETE	/scim/v2/Users/{id}	Removes user account
List Users	GET	/scim/v2/Users	Lists users with filtering
Create Group	POST	/scim/v2/Groups	Creates a group
Manage Group	PATCH	/scim/v2/Groups/{id}	Add/remove group members
