These were done a while ago but are worth mentioning.
My Parcel Locker
This integration has been updated with the latest information from the MPL API.
For sites using MPL, the new changes should be of no impact.
GroundFloor PL
GroundFloor integration was added mid-release in about July this year and has been rolled out to a number of sites.
GroundFloor supports a greater level of integration than MPL with synchronization of users between connecX and GF, removing the need for user accounts to be created manually.
In both cases, parcel locker deliveries create notifications for residents and provide parcel locker access codes or QR codes for resident to access their lockers. Collection notificaitons are also provided.
