Update a shipment line

PUT/
Changes one shipment line and recalculates the shipment. Send only what you change; returns the action envelope (UPDATED, or NONE when nothing changed).
- An
order_itemline can change itsquantityandposition, not the order line it points at. - A
shipment_costline can changename,description,shipment_package_id,shipment_estimate_id(null unlinks) and itspricing.
Numbers are { value, dp } pairs: value is the number without its decimal point and dp the count of decimal places, so 12.50 is { "value": 1250, "dp": 2 } (or { "value": 125, "dp": 1 }). value is a JSON integer or a digit string, never a float: 12.5 is refused. Quantities take up to 8 decimal places; shipping costs and a pricing mode's rate take 6. More significant decimals than that are a 422, not rounded. Send very large numbers as strings. Answers send prices at the stored scale (6 decimal places), quantities without trailing zeros, and _meta.subtotal (price × quantity) at the combined scale, compacted when it would exceed a safe integer: always read dp.
Business rules
- A line's kind can't change: 422 "Cannot update the product type...".
- A locked Shopify shipment (or one with a broken Shopify link): 422
validation_error"Cannot update Shopify-synced shipment item from API." - An externally synced line on a draft order: 422
validation_error"Publish this order before updating an externally synced shipment item.", witherror.context.reasonparent_order_publish_required. quantity.typeis required whenever you sendquantity, andpricing.typewhenever you sendpricing(422validation_failed).
Side effects
- Recalculates the shipment's cost and billable fee totals and the order's shipping totals.
- Updates each order line's shipped status (not allocated, partly, fully or over-allocated).
- On an Auto Invoice order, shipping cost lines are mirrored as shipping fees on the managed invoice.
- Open Admin Portal pages refresh, and so do Customer Portal pages the order's customer has open. No webhook or email is sent.

Errors
401The API key is missing or wrong (
unauthenticated).403You are not allowed to do this.
api_access_not_in_plan: your team's plan doesn't include API access (Pro and above, with an active subscription or trial), so every request answers this until the team upgrades. When your role lacks the permission the operation needs, the body is only{"message": "Insufficient Permission"}. Other refusals use the error envelope, withunauthorizedoruser_is_not_authorized.- When
- Your role can't edit this order.
- Fix
- Ask the team owner to adjust your role or assign you to the order.
404Not found.
page_not_found: the team slug is unknown, you are not a member of the team, or an id in the path is not one of this team's.code: null, with a message that starts "No query results for": there is no record with that id.- When
- The line isn't your team's.
- Fix
- Check the id.
422The request was refused and changed nothing.
validation_failedlists what to fix inerror.fields; other codes name a business rule, explained inerror.message. A few checks answer with only{"message": "..."}. An operation that calls another service (a payment provider, a carrier, an accounting app) can answerconnect_timeout("Please retry again") when that service does not answer in time: the change may or may not have happened there, so read the record back before you retry.- When
- Validation or a business rule fails.
- Fix
- Read
error.messageanderror.fields.
Notes
lock_versionis returned but not checked on shipment lines: the last write wins.
