Enterprise SSO

Enterprise Single Sign-On (SSO) lets organization members authenticate through your identity provider (IdP) over OIDC. This guide walks through configuring an OIDC application, registering it on the organization, verifying a domain so members are auto-routed to SSO, and choosing the right authentication requirement for the organization.

Overview

Enterprise SSO provides:

• OIDC sign-in through your identity provider (Okta, Azure AD, Google, or any compliant OIDC IdP)
• Email-domain auto-redirect: members signing in from a verified company domain are sent to your IdP automatically
• Organization-level authentication policy that can require MFA or restrict members to SSO only

Prerequisites

Before configuring SSO:

1. Insights plan for the organization — Insights grants both SSO and custom-domain verification.
2. Owner role in the organization — SSO and security settings are restricted to the organization owner.
3. An OIDC-compliant identity provider with the ability to register a confidential client.
4. A domain you can prove ownership of if you want email-based auto-redirect or stricter enforcement.

Organizations without the Insights entitlement receive the normal public API error shape with HTTP 403 and code: "FORBIDDEN"; provider credentials are not saved.

Step 1 — Configure your identity provider

Create an OIDC application in your IdP with these settings:

Identity provider examples

Okta

1. Create a new Web Application
2. Set the Sign-in redirect URI shown above
3. Enable the Authorization Code grant
4. Copy the Client ID and Client Secret

Azure AD

1. Register a new application
2. Add a Web platform redirect URI
3. Create a client secret
4. The Issuer URL is https://login.microsoftonline.com/{tenant-id}/v2.0

Step 2 — Register SSO on the organization

Once your IdP application exists, send the credentials to the API. SSO settings live under the organization, so the call is tenant-scoped — the organization id sits in the URL path and authentication is the same as any other API request (session cookie or X-Api-Key).

ORG_ID="01HZ3K5R4X9Y2V6QF8TJ7W0CDN"
curl -X PUT "https://api.indexhog.com/api/user/organizations/${ORG_ID}/settings/sso" \
-H "X-Api-Key: tkn_AbCdEf..." \
-H "Content-Type: application/json" \
-d '{
  "provider": "okta",
  "issuerUrl": "https://your-org.okta.com",
  "clientId": "your-client-id",
  "clientSecret": "your-secret"
}'

const apiKey = '<your-api-key>'; // load this from a secure env var — never hardcode
const organizationId = '01HZ3K5R4X9Y2V6QF8TJ7W0CDN';
const res = await fetch(
`https://api.indexhog.com/api/user/organizations/${organizationId}/settings/sso`,
{
  method: 'PUT',
  headers: {
    'X-Api-Key': apiKey,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    provider: 'okta',
    issuerUrl: 'https://your-org.okta.com',
    clientId: 'your-client-id',
    clientSecret: 'your-secret',
  }),
},
);

The request body has exactly four fields:

Email-domain auto-redirect is configured separately on the verified domain (Step 3), not on the SSO settings body. To remove SSO, send DELETE to the same URL.

Step 3 — Verify your domain

Domains are managed as a separate resource. Once a domain is verified, members signing in with a matching email address are auto-routed to your IdP, and the domain becomes eligible for auto-join and SSO enforcement.

1. Add the domain via POST /api/user/organizations/{organizationId}/domains — the response includes a DNS TXT record name and value.
2. Add that record to your DNS provider.
3. Trigger verification with POST /api/user/organizations/{organizationId}/domains/{domainId}/verify.

ORG_ID="01HZ3K5R4X9Y2V6QF8TJ7W0CDN"

# Add a domain

curl -X POST "https://api.indexhog.com/api/user/organizations/${ORG_ID}/domains" \
-H "X-Api-Key: tkn_AbCdEf..." \
-H "Content-Type: application/json" \
-d '{ "domain": "yourcompany.com" }'

# After publishing the DNS TXT record, run verification

DOMAIN_ID="01HZ3KA7V0J9Z8Q2G5B1T7XWDN"
curl -X POST "https://api.indexhog.com/api/user/organizations/${ORG_ID}/domains/${DOMAIN_ID}/verify" \
-H "X-Api-Key: tkn_AbCdEf..."

const apiKey = '<your-api-key>'; // load this from a secure env var — never hardcode
const organizationId = '01HZ3K5R4X9Y2V6QF8TJ7W0CDN';

// Add the domain
const added = await fetch(
`https://api.indexhog.com/api/user/organizations/${organizationId}/domains`,
{
method: 'POST',
headers: {
'X-Api-Key': apiKey,
'Content-Type': 'application/json',
},
body: JSON.stringify({ domain: 'yourcompany.com' }),
},
);

// After publishing the DNS TXT record, run verification
const domainId = '01HZ3KA7V0J9Z8Q2G5B1T7XWDN';
const verified = await fetch(
`https://api.indexhog.com/api/user/organizations/${organizationId}/domains/${domainId}/verify`,
{
method: 'POST',
headers: { 'X-Api-Key': apiKey },
},
);

Step 4 — Choose an authentication requirement

Each organization carries a security configuration with two fields. Update them via PUT /api/user/organizations/{organizationId}/settings/security.

PUT /api/user/organizations/{organizationId}/settings/security
{
"authRequired": "any",
"requireMfa": false
}

authRequired

requireMfa

A boolean that enforces MFA on session sign-ins independently of authRequired. PATs are not subject to MFA — scope and pin them carefully to keep automated access safe.

Test the configuration

Trigger a server-side validation of the configured issuer URL with POST /api/user/organizations/{organizationId}/settings/sso/test. It performs OIDC discovery against the saved issuer and returns whether the configuration is reachable. The endpoint takes no body.

{
"success": true,
"status": 200,
"code": "OK",
"message": "SSO configuration is valid",
"data": { "success": true, "message": "SSO configuration is valid" }
}

SSO login flow

Users with verified-domain emails follow this flow:

1. User submits an email at sign-in.
2. The sign-in flow detects a verified domain pointing to an SSO-enabled organization.
3. The client is redirected to /api/auth/sso/{slug}/login, which forwards to your IdP.
4. After IdP authentication, the IdP redirects back to /api/auth/sso/callback.
5. A session is established and the user is returned to the app.

/api/auth/sso/{slug}/login is the canonical entry point — {slug} is the organization's slug, available on GET /api/user/organizations.

Auto-join configuration

Each verified domain carries an auto-join policy. Update it via the domain settings endpoint to enable automatic organization membership for users with matching email domains. Optionally require admin approval before joining — pending requests can then be reviewed via the organization members API.

Troubleshooting

Best Practices

• Configure and test before enforcing: Set authRequired to any while you validate the IdP, then raise it once members can sign in.
• Keep at least one non-SSO admin during rollout: A backup credential prevents lockouts if the IdP misbehaves.
• Use a verified domain for auto-redirect: Without it, SSO works but members must navigate to the SSO login URL manually.
• Treat the client secret as sensitive: It is stored encrypted at rest, but anyone who can read it can sign in as your application.
• Document SSO sign-in for your team: Include the email they should use and the expected IdP screen to reduce support traffic.

Next Steps

After setting up SSO:

1. Configure API keys: Set up API Keys for integrations.
2. Review security settings: Manage settings via the Organizations API.
3. Manage domains: Add additional domains via the Organizations API.
