Overview
This guide outlines the integration of Opensense, an email signature management platform, with Okta Universal Directory. The integration enables read-only access to user directory information to dynamically personalize email signatures with real-time profile data. No write or admin access is granted.
Integration Components
Component | Description |
---|---|
Service | Opensense (Email Signature Management) |
Directory Source | Okta Universal Directory |
Integration Type | REST API using Okta API Token (Read-only) |
Data Flow | One-way: Okta ➜ Opensense (No data is pushed to Okta) |
Required Configuration Inputs
Parameter | Description |
---|---|
Okta Directory API URL | Example: |
API Token | A read-only API token generated in Okta Admin Console |
💡 The API token must be created from a dedicated API-only service account with minimal directory access.
Purpose of Access
The integration reads user and group data for the following functions:
Personalized Email Signatures: Pull user profile data (name, title, department) to generate dynamic email footers.
Conditional Signature Rules: Apply logic based on group or department for different signature formats.
Profile Syncing: Ensure signature updates reflect changes in Okta user profiles.
API Scopes and Permissions
The API token must be assigned the minimum necessary scopes:
Scope | Purpose |
---|---|
| Fetch user profile attributes (name, email, job title, etc.) |
| Retrieve group memberships (for conditional signature logic) |
| (Optional) If using app assignments for user scoping |
📌 Avoid assigning broader scopes. The principle of least privilege should be enforced.
Security Considerations
Access Scope
API token is read-only.
No capability to create, update, or delete users or groups.
Principle of Least Privilege
The service account should be scoped only to necessary user and group data.
Avoid granting access to unnecessary Okta directories or applications.
Secure Storage & Transmission
Tokens are encrypted at rest by Opensense.
All communication between Opensense and Okta occurs over HTTPS (TLS 1.2+).
Token Lifecycle Management
Token can be revoked or rotated via:
Okta Admin Console → Security → API → TokensOpensense supports seamless re-authentication after token replacement.
Zero Access to Authentication or Mail
The integration does not access:
User authentication flows
Mailboxes or email content
Admin or app control interfaces
