Testing against a live sandbox
The SCIM Playground at scim.dev (base URLhttps://api.scim.dev) is a free, live SCIM 2.0 API. Point a SCIM Token connection at it with your scim.dev API key to see the full connector lifecycle against a compliant implementation before touching a real tenant. It’s also the fastest way to compare your own application’s SCIM responses against a known-good reference.
Lifecycle payloads
Listing users (sync)
Lumos pages through/Users with standard SCIM pagination parameters:
ListResponse with totalResults, and each user carries at minimum id, userName, emails, and active:
/Users response against this shape first. Missing userName or emails attributes and broken pagination are the two most common causes.
Creating a user (provisioning)
id. Lumos uses that id for every later operation on the account.
Deactivating a user (deprovisioning)
A partial update settingactive to false:
DELETE /scim/v2/Users/{id} instead. Which one Lumos calls depends on the deprovisioning action configured for the app.
Managing group membership
Group assignment and removal are PATCH operations against the group, not the user:"op": "remove" with the same shape. If membership changes fail, check that your provider supports PATCH on /Groups (some only support PUT replacement) in its /ServiceProviderConfig.
Custom attributes
Attributes beyond the core schema, such as the enterprise extension’sdepartment or employeeNumber, sync into Lumos as custom attributes. Lumos discovers them from your API’s /Schemas endpoint. If an expected attribute isn’t appearing, confirm your provider declares it in its schema response and populates it on user records:
Verifying a provider before connecting
Three requests tell you most of what you need:GET /ServiceProviderConfig: confirms SCIM 2.0 and lists supported operations (PATCH support matters for groups and deactivation).GET /Users?count=1: confirms auth works and shows you the user shape, including which attributes are populated.GET /Groups?count=1: confirms groups havedisplayNameand a well-formedmembersarray.
