PATCH /psa/allocations

Retry-safe: A write that accepts Idempotency-Key: repeating a request with the same key replays the stored answer instead of executing twice.

Updates multiple allocations in one request, with the fields you send. A field you leave out keeps its current value. To clear notes or workingDays, send null.

To reassign an allocation, send a new memberId. memberEmployeeId, memberPlaceholderId, and psaProjectId are ignored, and an allocation can't move to another project. Every update recalculates the allocation's daily entries from its dates, totalHours, method, and workingDays.

If any id matches no allocation, the request fails with NOT_FOUND and nothing is updated. The response is empty. Read an updated allocation with GET psa/allocations/:id.

Parameters

Name In Type Required Description
Api-Version header string · v1 yes The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version v1.
Idempotency-Key header string no An opaque caller-chosen string (1-255 characters) that makes this request safe to retry. Repeating the same key with an identical request body replays the original response instead of re-executing - but only once that original request succeeded; a failed attempt re-executes on retry. Repeating the key with a different body is answered with 422. A key still in flight is answered with 409 - as is a key whose original request was interrupted before it finished, for a few minutes afterwards, until that attempt is presumed dead. A completed response stays replayable for 24 hours. The key is scoped to the caller, not to the action: reusing it for a different action is answered with 409 or 422 rather than treated independently. On read actions this header is ignored. On write actions that cannot offer the guarantee it is answered with 400 IDEMPOTENCY_NOT_SUPPORTED rather than silently ignored.

Request body

Required, application/json: updateAllocationsInput.

Field Type Required Description
allocations array<object> yes The allocations to update. Example: [{"id":"3f2a91c7-5d84-4b1e-9c60-8a7e2d4f0b13","totalHours":"32.00"},{"id":"b7c40e29-1af6-42d8-8e55-6d3b9c018a74","memberId":51204,"projectActivityId":8317,"startDate":"2026-09-01","endDate":"2026-11-30","totalHours":"160.00","method":"hoursPerWeek","notes":"Rescoped after the change order.","workingDays":["Monday","Tuesday","Wednesday","Thursday"],"memberEmployeeId":3889611,"psaProjectId":32341}].
allocations[].id string yes The unique identifier of the allocation to update. The call is all-or-nothing: if any identifier matches no allocation, nothing is updated.
allocations[].memberId number no A new timetracking member assignment to book the allocation against. It is a numeric key, not the UUID that GET psa/team-members/:id takes.
allocations[].projectActivityId number no A new project activity for the allocation. It is a numeric key, not the UUID that GET psa/activities/:id takes.
allocations[].startDate date no A new first day of the allocation period, inclusive. Use format YYYY-MM-DD.
allocations[].endDate date no A new last day of the allocation period, inclusive. Use format YYYY-MM-DD.
allocations[].totalHours decimal no New planned hours, interpreted according to method as on create. Changing this regenerates the allocation's daily entries.
allocations[].method any no The distribution method for the planned hours. One of: "totalHours", "hoursPerDay", "hoursPerWeek", "hoursPerMonth".
allocations[].notes string | null no Free-form notes stored on the allocation.
allocations[].workingDays array<any> | null no The days of the week the allocation applies to.
allocations[].psaProjectId number no The PSA project of the allocation. It's ignored on update, because an allocation can't change project. It's a numeric key, not the UUID that GET psa/projects/:id takes.
allocations[].memberEmployeeId number | null no The employee on the allocation. It's ignored on update. To reassign the allocation, send memberId.
allocations[].memberPlaceholderId number | null no The placeholder on the allocation. It's ignored on update. To reassign the allocation, send memberId.
