How to connect: credentials you need

Western Post uses a single connection type. Add a Western Post source, start configuring an operation, and when Flxpoint prompts you click + New Connection, enter the APP KEY, APP TOKEN and Environment, then Test Connection → Save Connection.

Field	What to enter
APP KEYRequired	Issued by Western Post for this connection.
APP TOKENRequired	Issued by Western Post for this connection.
EnvironmentRequired	The Western Post environment this connection targets.

The APP KEY and APP TOKEN are issued by Western Post. Request them from your Western Post account contact if you don't already have them, and confirm which Environment your account is provisioned for.

Important: read before configuring

Three credentials are required

The connection needs the APP KEY, APP TOKEN and Environment. All three must be present for the connection to test successfully. Domain, Retailer ID, Consumer Key and Consumer Secret are not used by this connection.

Common issues

Test Connection fails

All three values are required: APP KEY, APP TOKEN and Environment. Note that Domain, Retailer ID, Consumer Key and Consumer Secret are not used by this connection, so filling those does not help.

Stock numbers look off

Map the sellable bucket to quantity: it is the saleable on-hand count. The other buckets (unsellable, reserved, pending, onway and so on) are breakdowns Western Post reports alongside it.

Shipments come in without a ship date

Western Post does not always return Shipped At. When it is missing, Flxpoint stamps the shipment with the sync time.

FAQs

Where do the APP KEY and APP TOKEN come from?

They are issued by Western Post. Request them from your Western Post account contact, and confirm which Environment your account is provisioned for.

Which quantity field should I map to stock?

The sellable field. Map the other warehouse buckets only if you need the breakdown.

Does Western Post support cross-border shipments?

Yes. The feed carries productDeclaredName and productDeclaredValue, the customs declaration name and value used on cross-border shipments.
