Bulk-update multiple When I Work shifts in a single API request
domain: hr-payroll · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate and obtain a session token as described in When I Work's auth flow
Build an array of shift objects, each including the shift ID and only the fields being changed
Submit the array to the shifts update endpoint in one request instead of issuing one call per shift
Inspect the response for per-item results, since a batch call can partially succeed
Re-fetch affected shifts after the update to confirm the final state, especially for shifts linked to Schedules/Locations or Positions
Known gotchas
Because Shifts link to Schedules, Positions, Sites, Users, Tasks, and Tags, a bulk update that changes a shared attribute can have wider downstream effects than a single-shift edit
Confirm which fields are safely batchable versus which require individual calls, since not all fields necessarily support bulk semantics
Session tokens obtained via user login can expire mid-batch on large jobs - handle re-authentication defensively
