Endpoints#

GET/shipments/{id}/packages 200422

Packages in a shipment, with their tracking numbers.

Parcel-level detail: what went in which box, what it weighed, what the carrier charged, and the tracking number. This is where tracking numbers live. The order-level audit trail records that a shipment happened; the number a customer types into a carrier's site is here, per package - which matters because one shipment is often several boxes with several numbers.

Requires scope shipments:read.

Parameters

Name	In	Type	Notes
idrequired	path	integer	The shipment id.

When it fails

Status	Code	Meaning
422	unknown_value	No such parent record in this company.

Body array

Field	Type	Description

Parameters

Name	In	Type	Notes
locationid	query	string	Restrict to one locationid.
orderid	query	string	Restrict to one orderid.
invoiceid	query	string	Restrict to one invoiceid.
cancel	query	string	Defaults to `false`. Pass `true` or `any`.
modifiedsince	query	string	RFC 3339 UTC timestamp. Returns only records changed since then, including cancelled ones - so `cancel` defaults to any rather than `false` when this is used. The response carries `_meta.synced_through`; store it and send it back next time.
externalid	query	string	Exact match on your own key.
include	query	string	Comma-separated extras to embed. Only `custom_fields` is available: the extra fields this install has defined on the record. Off by default, and an unrecognised value is refused rather than ignored. See Conventions.

Status	Code	Meaning

POST/shipments/{id}/invoice 200404409422

Invoice this shipment.

Not available through the API yet. The single-shipment branch of arorder2invoice.php terminates the request with its own page output, so this cannot be served as JSON without changing page code.

Requires scope invoices:write.

Parameters

invoicedate	string	Invoice date. Defaults to what NolaPro would use.

When it fails

Status	Code	Meaning
