Courier-assigned v3 webhook update: Stacked packages

:new: What’s new?

We are pleased to announce an enhancement to the courier assigned webhook event. We’re introducing a new field, “details.packages” that includes the ID(s) of the stacked packages, when applicable.

:bulb: How does it work?

The payload now includes a new “packages” field. This new field is an array that lists the IDs of additional stacked packages, if any.


"details": {
    "account": {
        "id": 1
    "courier": {
        "name": "Adriel Pfeffer"
    "package": {
        "id": "10000000001",
        "reference": "1682689274",
        "tracking_url": ""
    "packages": [
