Update a receipt

Operation ID: updateReceipt

Group: Inventory › Receipts

PATCH /inventory/receipts/{id}

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

Updates a receipt with the fields you send. A field you leave out keeps its current value.

Use the receipt's id, not its documentNumber.

Lines change through three separate arrays. updateLines and createLines are applied first, then deleteLines. Leave out all three to keep the lines as they are. On an updateLines item, a field you leave out keeps its current value.

On an updateLines item, sending batches, serials, or binLocations replaces all of that line's tracking, so send every batch, serial, and bin detail the line should keep. Leave all three out to keep the line's tracking as it is.

Changes a draft receipt's details and its lines. A receipt in any other status can't be changed.

One request can remove a line and add its replacement. If a line id in deleteLines or updateLines is not on this receipt, the request fails with REFERENCE_NOT_FOUND.

Every line's warehouse must belong to the receipt's legal entity, including a line moved to another warehouse. Otherwise the request fails with LOCATION_ENTITY_MISMATCH.

The response is the updated receipt, with the same fields GET inventory/receipts/:id returns.

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.
`id`	path	string	yes	The unique identifier of the receipt you want to update.
