Check these setup points in this order:

1. EasyPost's status page, in case EasyPost itself has a problem (see How do I check whether EasyPost is having problems?).
2. In Configuration > Delivery > Delivery Computation, the EasyPost row has Is active ticked on this storefront.
3. Api Key holds the key for the mode you want: your test key while testing, your production key when live.
4. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Vendor Info, every required ship-from field is filled in and Vendor's Country (Two Letter Iso Code) is a two-letter code such as GB or US.
5. If you use Auto calculated parcels, Auto Calculated Parcel Max Weight and Auto Calculated Parcel Max Size are filled in (a blank Max Size stops rates) and not left at the default of 1, which splits baskets into many parcels and inflates rates.
6. At least one service in Carriers and Services has Enabled for Checkout ticked.
7. In EasyPost, under Account Settings > Carriers, the carrier you expect is connected.

If all of these are right, turn on verbose logging and look at the log for the request.

Checkout only tells your customers that something went wrong. The reason is written to your store's log, but only while verbose logging is on.

1. Go to Configuration > Settings > Integrations > Connect Settings.
2. Tick Verbose Logging Enabled.
3. Check Verbose logging areas. Keep Get Price, Create Quote, Create Order and Webhooks ticked unless you only need one area. Clearing every area stops area logging.
4. Save the page.
5. Repeat the problem, for example go to the delivery step at checkout, and note the time.
6. Read the new log entries, or send the time of your test to support.
7. Untick Verbose Logging Enabled when you have finished. The entries are large, so don't leave it on.

If Disable verbose logging platform wide is set, verbose logging stays off for your store. Do not use the plugin's Debug Mode for this: it shows the details to shoppers at checkout.

If rates or labels stop working for every order at once, check EasyPost's own status page before you change any settings.

1. Open easypoststatus.com.
2. Look at the parts that matter to you, for example API, Label Purchases, Webhooks or your carrier.
3. If EasyPost reports a problem or maintenance, wait for it to clear, then try again.

Learn more: EasyPost status page

Your customers see No shipping options found when no EasyPost rate came back. Work through these checks in order.

1. Rates are switched on. Go to Configuration > Delivery > Delivery Computation and check the EasyPost row has Is active ticked.
2. Your ship-from details are complete. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Vendor Info, fill in Vendor's Company Name, Vendor's Phone and Vendor's Zip Postal Code. Enter Vendor's Country (Two Letter Iso Code) as a two-letter code such as GB or US.
3. Your store has the measures EasyPost needs. In Configuration > Measures, you need a weight measure with the system keyword ounce and a dimension measure with the system keyword inches.
4. Your currencies exist. Every currency EasyPost quotes in must be set up in Configuration > Currencies. If one is missing, every rate from that request is lost.
5. Parcel limits are filled in. Under Parcels, Auto Calculated Parcel Max Size must not be blank.
6. The services are switched on. Under Carriers and Services, pick each carrier in Select carrier and check Enabled for Checkout is ticked for the services you want. This list only filters the rates EasyPost returns. It never creates a rate.
7. Your carrier accounts work. In your EasyPost account, check the carrier is connected under Account Settings > Carriers.
8. EasyPost itself is working. Check easypoststatus.com.

If something fails part-way, checkout can show a technical message instead, for example Object reference not set to an instance of an object. Look it up in the error messages below. Still stuck? Turn on verbose logging, repeat the checkout and read the log.

Check Connection only proves EasyPost accepts your keys. It lists your carrier accounts with the Production Api Key and lists shipments with the Api Key. It does not ask for a rate, so it can pass while checkout still shows no rates.

Next, work through Why does checkout say "No shipping options found"? above. The most common gaps are Is active not ticked in Configuration > Delivery > Delivery Computation, incomplete Vendor Info, and services not ticked as Enabled for Checkout.

Learn more: Lesson 4: Turn EasyPost on and connect your keys | Lesson 8: Test it as a customer

High rates nearly always come from how parcels are built, or from extra charges added on top. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), check these in order.

1. Parcel limits left at 1. Under Parcels, Auto Calculated Parcel Max Weight and Auto Calculated Parcel Max Size both start at 1. Left like that, one order is split into many tiny parcels and every parcel is charged. Set them to the real limits of the parcels you send.
2. Parcels Allocation Level. OrderLineQuantity makes at least one parcel per unit. OrderLine makes at least one per order line.
3. Predefined parcels. In Predefined Parcels mode, every box in the Predefined parcels grid is quoted together.
4. Multiply Quantity by Record Count. If it is ticked, quantity is multiplied by record count when parcels are worked out.
5. Cube root. Check Use cube root for determining total package dimension in Configuration > Settings > Delivery Settings. It is used to estimate the size of stacked items.
6. Your own fees. The fees under Shipping Fees and any fees on a service are added together.
7. Rate type. Rate type set to Retail Rate or List Rate shows a price other than the rate you actually pay (Rate).
8. Test mode. With a test key, EasyPost returns retail or slightly discounted rates, not your negotiated rates (USPS through the EasyPost Wallet is an exception).
9. Exchange rate. Rates are converted into your store currency with the exchange rate in Configuration > Currencies. Check it is up to date.

When the items in a parcel group are heavier than Auto Calculated Parcel Max Weight or bigger than Auto Calculated Parcel Max Size, the group is split into several parcels. The goods are shared out across them, so each parcel sent to EasyPost is smaller than the real goods and the carrier charges for every one.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Parcels, replace the default 1 in both max fields with real limits. Max Weight is in ounces. Max Size is a girth figure in inches: 2 × length + 2 × height + width.
2. Give every product variant a real weight and real dimensions. Products with no dimensions are sent at the minimum size of 1 inch.
3. Turn on Use cube root for determining total package dimension in Configuration > Settings > Delivery Settings.
4. Run a test checkout and compare the rate with what you expect.

This happens when Parcel Size Calculation is set to Predefined Parcels. With Parcels Allocation Level set to Order, every box in the Predefined parcels grid is quoted at its fixed size and weight, whatever is in the basket. The storefront does not pick a best-fitting box.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Parcels, set Parcel Size Calculation to Auto calculated.
2. Set real values in the two max fields.
3. Make sure every product variant has a real per-unit weight and size.

If you must keep predefined boxes, Use Infigo calculated weight in parcels fills in the calculated weight for any box whose weight is 0.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Carriers and Services, pick the carrier in Select carrier.
2. Find the service in the table and check Enabled for Checkout is ticked. If not, click Edit, tick it and click Save. Services EasyPost returns that the storefront did not know about are added switched off for checkout, and so are built-in services added to a carrier later.
3. If the service is not in the table at all, click Add Service and type the service code exactly as EasyPost names it. For example, UPS GroundSaver is added this way.
4. Remember the table only filters what EasyPost sends back. It never creates a rate.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under General, check Signature and Saturday delivery. Optional shows every service both with and without that option, so services repeat with "Signed" or "Saturday" in the name. Choose None or Required to show each service once.
2. In your EasyPost account, under Account Settings > Carriers, check you have only one account connected for that carrier.
3. In Configuration > Delivery > Delivery Computation, check no other active method also returns rates for the same carrier.

Learn more: Lesson 7: Choose carriers and services

The Carriers and Services list shows the carrier accounts in your EasyPost account, read with the Production Api Key. If the box only shows "The carriers and services settings will be availble after you enter valid ApiKeys and save it", your Production Api Key is blank or not valid.

1. In your EasyPost account, open Account Settings > Carriers and check the carrier is connected. If not, click Add Carrier. It must be on your production account, even while you test.
2. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), check Production Api Key holds your production key, then click Save.
3. Wait about a minute and reload the page. The carrier list is kept for a short time before it is read again.

Watch out: if you save the settings while a carrier is missing from your production EasyPost account, its service settings and manifest settings are deleted. Reconnect the carrier in EasyPost before you save.

This is the plugin's Debug Mode. It writes the parcel calculation into the delivery option text your customers see.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under General, untick Debug Mode.
2. Click Save.

Keep it off on a live store. To investigate a problem, use verbose logging instead.

Learn more: Lesson 8: Test it as a customer

If only one delivery option is available and the order setting below is ticked, checkout skips the delivery step, so your customers never see the list of rates.

1. Go to Configuration > Settings > Order Settings.
2. Find Hide delivery method step if only one options is available under Checkout Flow.
3. Untick it if your customers should always see and confirm the delivery step, then save.

If you expected several EasyPost services but only one shows, see A service I want doesn't show at checkout.

For each item in the basket, your storefront sends EasyPost a weight worked out like this:

• If the item's job has its own weight, that weight is used. A pricing script can set this weight.
• Otherwise the product variant's weight is used, plus any weight added by the attributes the customer chose.

Things to know:

• If a pricing script sets the weight to 0, 0 is used. A parcel that ends up under 1 ounce is sent to EasyPost as 1 ounce, so you still get a rate, but it is the rate for a 1-ounce parcel.
• For MegaEdit products with Adjust ME weight ticked, the job weight is recalculated from the product, its attributes and the pages or stock, and that weight is what EasyPost receives. This can raise rates.
• Use Infigo calculated weight in parcels only fills in a parcel's weight when the parcel's own weight is 0. It applies to predefined parcels and to parcels you add by hand in the order's shipping panel.

If rates look wrong, check the weight on the exact product variant you are testing with, and any pricing script that sets weight.

Labels are only bought automatically when Is Buy Shipping Instantly is ticked on the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under General. It is off by default. When it is on, the purchase is tried when one of these happens:

• the order status changes to Complete or Confirmed;
• an order line is approved;
• the payment status becomes Paid;
• a line's production status becomes Complete;
• output is created for an order line;
• the order is sent to Connect plugins, following Send to Connect plugins when in Connect Settings.

Even then, nothing is bought if:

• no line in the order has shipping enabled;
• the order's delivery method is not an EasyPost rate or a delivery method mapped with Connect Link;
• the order is not ready yet;
• a label has already been bought for the order (it runs once only);
• the order is international and Use accurate customs info is off. The lines then show Connect Additional Action Required.

To ship the order now, open it in your admin area, go to the Delivery info tab, click Show shipping information and click Create Shipment.

Every label you buy is always available in the order's shipping panel under Postage labels. Copies only go to a hotfolder if you set one.

1. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), find Plugin Artifacts.
2. Enter a hotfolder id in Labels (Paperwork) Hotfolder Id. The hint under the field lists the hotfolders you can use.
3. If you also want packaging slips or job paperwork copied, fill in Packaging Slip hot folder and the Job Ticket hot folder field below it. These do nothing unless Labels (Paperwork) Hotfolder Id is set.
4. Click Save.

EasyPost offers two kinds of carrier account:

• EasyPost Wallet carriers: accounts EasyPost provides, paid from your EasyPost wallet. Each one only covers certain origin countries, and many are for shipments from the US. Check EasyPost's Wallet page for where you ship from.
• Your own carrier accounts: your own contract with a carrier, added in EasyPost under Account Settings > Carriers > Add Carrier. If no Wallet carrier covers the country you ship from, you need one of these. Using your own carrier accounts needs EasyPost's Bring Your Own Carrier Accounts plan; check EasyPost's current pricing.

Credentials and sign-in problems for your own carrier accounts are fixed in the EasyPost dashboard, not in your storefront.

• EasyPost Wallet carriers are paid from your EasyPost Wallet. Keep it funded or turn on auto-reload, otherwise label purchases fail.
• Your own carrier accounts are billed by the carrier for postage, and EasyPost bills its plan and label fees.

To use your own carrier account, for example your Royal Mail or DPD contract, your EasyPost account needs EasyPost's Bring Your Own Carrier Accounts plan (required since April 2026). Then add the account in EasyPost under Account Settings > Carriers > Add Carrier. On EasyPost's Wallet plan, your own carrier accounts are switched off and hidden, but not deleted.

Yes. Map one of your own delivery methods, such as a fixed rate or shipping by weight method, to an EasyPost service with the green Connect Link button in Configuration > Delivery > Delivery Methods. Your customers pay the delivery method's price. The label is bought from EasyPost for the service you mapped.

Only services with Enabled for connect plugins ticked can be chosen in the mapping.

Not inside the EasyPost settings. Use your storefront's own tools instead:

• the usage rule Usage requirement by Shipping Country;
• departments, which control which delivery methods each group of customers gets;
• your own delivery methods mapped to EasyPost with Connect Link.

Your products can keep your store's own weight and size units. They are converted to ounces and inches before they are sent, because EasyPost works only in ounces and inches. For that, your store needs the ounce and inches measures.

The EasyPost settings themselves (the parcel max weight and size, and predefined parcel sizes) are entered in ounces and inches.

Yes. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Carriers and Services, pick the carrier and click Edit on the service.

• Untick Enabled for Checkout to hide it.
• Type a Friendly Name to show your own name instead of EasyPost's.

Yes. On the EasyPost Settings page (Configuration > Plugins > Connect Plugins, then Configure on the EasyPost row), under Shipping Fees, set Additional Shipping Fee type to Absolute amount or Percentage, then fill in Additional Shipping Fee Per Parcel and/or Additional Shipping Fee Per Order.

Show Delivery Date/Days shows the carrier's own transit time from EasyPost. It does not include your production time. If that misleads your customers, set it to No.

If you use delivery restrictions, Use Easypost Delivery Days in delivery offsets uses EasyPost's delivery days in place of the day offset set in the restriction.

From your storefront, EasyPost does not:

• ship from more than one address (each storefront has one ship-from address, under Vendor Info);
• verify addresses;
• create returns or return labels;
• book pickups;
• add insurance;
• refund or void labels;
• change the label format or size;
• update orders to Shipped or Delivered.

The reference sent with each shipment is set by your storefront and can't be changed.

Your admin role needs these permissions:

For the full integration, yes. Each part does a different job.

• Configuration > Delivery > Delivery Computation, EasyPost Is active: live rates at checkout.
• Configuration > Settings > Integrations > Connect Settings, EasyPost ticked in Enabled Connect Plugin and Connect Plugins to Handle Delivery: labels, the order's shipping panel, tracking and manifests.

Only partly. EasyPost rate requests ignore a product's free-shipping setting, so a free-shipping item still adds its weight to the rate. Your storefront sets delivery to zero only when every item in the basket has free shipping, or the customer has a role with free shipping.

If you need an item to add nothing to the rate, turn shipping off for that product instead. Items with shipping turned off are left out of the EasyPost request.

Yes. Every delivery computation method that is active adds its options to the same list at checkout. If, for example, Fixed Rate Shipping and EasyPost both have Is active ticked in Configuration > Delivery > Delivery Computation, your customers see your fixed-rate methods and the live EasyPost rates together.

To control who sees what, use the Usage rules button on each row in Delivery Computation, or departments. Apart from your EasyPost service settings (such as Enabled for Checkout), only usage rules and departments remove options from this list.

To set up the fixed-rate methods themselves, see Managing the basics of shipping and payment. To charge your own price but still buy an EasyPost label, map the method with Connect Link instead.

EasyPost has two switches. Turn off the parts you no longer want:

• Rates at checkout: in Configuration > Delivery > Delivery Computation, click Edit on the EasyPost row, untick Is active and click Update.
• Labels, tracking and manifests: in Configuration > Settings > Integrations > Connect Settings, untick EasyPost under Enabled Connect Plugin and click Save. EasyPost webhook messages are then refused.

Before you switch off rates, make sure another delivery method is active, or your customers will have nothing to choose at checkout.
