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.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
- None of the ids is a shipment of your team (
shipment_not_found). - Fix
- Send shipment hash ids from Filter shipments.
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
- More than 100 ids (
limit_reached), or an item without a validid. - Fix
- Send at most 100
{ "id": ... }objects.
