Royal Mail labels, printed as the parcel is packed.
Through Royal Mail's Pro Shipping API: labels with customs details and service extras, tracking, cancelling, and an optional switch to Large Letter for items that qualify.
Royal Mail labels straight from your warehouse, without retyping a thing.
For many UK sellers, Royal Mail is the everyday courier, and the label is where the time goes. Someone copies the address from the order into Royal Mail's own screens, picks the service, types the customs details for parcels going abroad, then copies the tracking number back. It is slow, and a single wrong digit in a postcode or a forgotten customs line means a parcel that comes back.
With Pulsa connected, the label is made from the order itself. Your team picks and packs by scan, and the Royal Mail label is printed at packing, or for every order when a picking list is finished. The service comes from the delivery option the customer chose, customs items travel with international parcels, and the tracking link is saved on the order. A label can be cancelled from the orders list.
You keep your own Royal Mail business account, your contract and your rates. Pulsa uses the Pro Shipping API, so it suits sellers whose account has access to it. Picking, packing and stock work as for any other order; only the label step changes. If your account runs on Royal Mail Click & Drop instead, there is a separate integration for that.

Questions about Royal Mail
What does the Royal Mail integration do?
It creates Royal Mail labels from your orders as they are packed, with customs details for international parcels, and saves the tracking link on each order. Labels can also be cancelled from Pulsa.
Do I need a developer to set it up?
No. You paste the API credentials and shipping account from your Royal Mail account, then match your delivery options to Royal Mail services on one page.
Can I send parcels abroad?
Yes. Labels carry the customs items that international parcels need.
Can I try it before the whole team uses it?
Yes. Print and check the first labels on a few orders before switching your daily work over. A label you do not need can be cancelled from the orders list.
Can I use Royal Mail alongside other couriers?
Yes. Each delivery option in your shops is matched to a service, so some orders can go with Royal Mail and others with another courier connected to Pulsa.
How is this different from Click & Drop?
This integration uses Royal Mail's Pro Shipping API. Click & Drop is a separate integration for accounts that use Royal Mail's Click & Drop platform. Choose the one your Royal Mail account uses.
