If you have a corporate account with Hermes you can connect to their corporate shipment API.
This tends to be for high volume shippers.
You'll need to contact your account manager who will be able to provide the following details:
Hermes sometimes might ask for all the IP addresses to whitelist to connect to their API. All our IP addresses have already been whitelisted and no further action needs to be taken here
Child Client Mappings:
If you are operating in a 3PL context and the client is using your hermes shipping account it's possible to brand shipments to front end customers so instead of coming through as the 3PL e.g. "Mintsoft Fulfillment have a parcel for you" it could be "My Brand have a parcel for you"
You need to advise hermes of the clients you want to configure they will then supply you with the fields that we need.
Click Manage Client Mappings:
You can then view or manage all the mappings
e.g. for Client aa-testclient it would supply ChildClientId and ChildClientName.
