Workday RaaS 403 "not authorized" when the agent's integration user lost a security group

Workday RaaS 403 "not authorized" when the agent's integration user lost a security group

TL;DR

The integration user's security group assignment changed, and Workday started 403ing its report calls. Re-grant the security group (or the underlying domain permissions), and monitor the integration user's group membership. Permission drift is the usual cause of 'it worked yesterday'.

403 Forbidden: "not authorized" (Workday RaaS, integration user lost security group)

Steps

1. Confirm the drift: compare the integration user's current security groups against the known-good set. Expected: The missing group is identified.

2. Re-grant the security group or have the Workday admin restore it. Expected: Calls succeed again.

3. Find what removed it: an automated deprovisioning, a role change, or a tenant config push. Expected: The cause is known.

4. Monitor the integration user's group membership with a periodic check. Expected: The next drift pages before it breaks the sync.

5. Document the required groups as code or config so rebuilds restore them. Expected: The permission set is reproducible.

When to use

• Workday RaaS 403s on previously working calls
• the integration user's groups changed
• after tenant updates or deprovisioning runs

When not to use

• it never worked (then the groups were never right; configure from scratch)
• the 403 is on a specific report (check the report's own permissions)
• the credentials expired (that is a 401, not a 403)

Tool compatibility

• Workday RaaS
• security group administration

Variant phrasings

• "workday 403 not authorized integration user"
• "workday security group lost"
• "workday raas forbidden"

Why it happens

Workday permissions flow through security groups, and integration users are subject to the same lifecycle as humans: role changes, automated cleanups, and tenant refreshes all move group memberships. The agent's calls did not change; the user's permissions did. 'It worked yesterday' almost always means drift.

Edge cases

• tenant refreshes from production can wipe test-tenant group assignments; reapply after refresh
• the monitor should check effective permissions, not just group names
• document the groups outside Workday; the tenant is not its own backup
