SCIM ProvisioningDoc Design

Why SCIM docs matter

SCIM (System for Cross-domain Identity Management) is the standard protocol for automated user provisioning. Poor docs cause integration backlogs, support tickets, and churn. Great docs turn a multi-week integration into a one-afternoon task.

Core recipe

1. 1
   Schema map first.

   List every SCIM attribute your service consumes. Mark required vs optional. Document mutability (readWrite, readOnly, immutable). Include a full example User and Group resource.

2. 2
   Endpoint contract.

   Document every endpoint: GET/POST/PUT/PATCH/DELETE for /Users and /Groups. Include query filters (eq, sw, co), pagination (startIndex, count), and exclusion attributes.

3. 3
   Error catalog.

   Every SCIM error response must include status, scimType, and detail. Publish a complete table of scimType values (uniqueness, invalidFilter, mutability, etc.) with resolution steps.

4. 4
   Auth & rate limits.

   Specify bearer token format, OAuth2 grant flow, scopes required per endpoint, and rate-limit headers (X-RateLimit-Remaining). Include a curl example that works in one copy-paste.

IdP-specific guides

Supplement the generic SCIM doc with short, tested guides for Okta, Entra ID, and OneLogin. Each guide should include the exact provisioning app setup steps, attribute mapping screenshots, and a troubleshooting FAQ for the top three integration failures.
