This gem integrates ShipStation with Solidus. It enables ShipStation to pull shipments from the system and update tracking numbers.

This integration is a fork of spree_shipstation that adds Solidus and Rails 4.2+ compatibility.

Add solidus_shipstation to your Gemfile:

gem 'solidus_shipstation', github: 'solidusio-contrib/solidus_shipstation'

Bundle your dependencies and run the installation generator:

bin/rails generate solidus_shipstation:install

The installer will create a configuration initializer that you'll need to customize.

The installer will also create a migration, which is required by the API integration. If you are going to use the XML integration, feel free to delete the migration file, as those columns won't be used by the extension.

This extension can integrate with ShipStation in two ways.

The XML integration works by exposing a route in your Solidus application that generates an XML feed of all recently created and updated shipments in your Solidus store.

In order to enable the XML integration, make sure to configure the relevant section of the configuration initializer, and configure your ShipStation store accordingly:

• Username: the username defined in your configuration.
• Password: the password defined in your configuration.
• URL to custom page: https://yourdomain.com/shipstation.xml.

You can also configure your ShipStation store to pull the XML feed automatically on a recurring basis, or manually by clicking the "Refresh stores" button.

There are five shipment states for an order (= shipment) in ShipStation. These states do not necessarily align with Solidus, but you can configure ShipStation to create a mapping for your specific needs. Here's the recommended mapping:

Once you've configured the XML integration in your app and ShipStation, there's nothing else you need to do. ShipStation will

There's nothing you need to do. Once properly configured, the integration just works!

There are a few gotchas you need to be aware of:

• If you change the shipping method of an order in ShipStation, the change will not be reflected in Solidus and the tracking link might not work properly.
• When shipstation_capture_at_notification is enabled, any errors during payment capture will prevent the update of the shipment's tracking number.

The API integration works by calling the ShipStation API to sync all of your shipments continuously.

Because ShipStation has very low rate limits (i.e., 40 reqs/minute at the time of writing), the API integration does not send an API request for every single shipment update, as you would expect from a traditional API integration.

Instead, a background job runs on a recurring basis and batches together all the shipments that need to be created or updated in ShipStation. These shipments are then sent in groups of 100 (by default) to ShipStation's bulk order upsert endpoint.

This allows us to work around ShipStation's rate limit and sync up to 4000 shipments/minute.

As you may imagine, this technique also comes at the expense of some additional complexity in the implementation, but the extension abstracts it all away for you.

In order to enable the API integration, make sure to configure the relevant section of the configuration initializer. At the very least, the integration needs to know your API credentials and store ID, but there are additional options you can configure — just look at the initializer!

Once you've configured the integration, you will also need to enqueue the ScheduleShipmentSyncsJob on a recurring basis, to kick off the synchronization process. Because every app uses a different background processing library, this is left up to the user.

Here's what an example with sidekiq-scheduler might look like:

# config/sidekiq.yml
:schedule:
  schedule_shipment_syncs:
    every: ['1m', first_in: '0s']
    class: 'SolidusShipstation::Api::ScheduleShipmentSyncsJob'

This will schedule the job to run every minute. This is generally a good starting point, but feel free to adjust it as needed.

There's one possible problem you need to be aware of, when integrating via the API.

You should make sure the interval between your syncs is, on average, larger than your latency in processing background jobs, or you are going to experience sync overlaps.

As an example, if it takes your Sidekiq process 10 seconds to execute a job from the time it's scheduled, but you schedule a shipment sync every 5 seconds, your sync jobs will start overlapping, making your latency even worse.

This is a problem that is faced by all recurring jobs. The solution is two-fold:

1. Monitor the latency of your background processing queues. Seriously, do it.
2. Make sure your sync interval is not too aggressive: unless you really need to, there's no point in syncing your shipments more often than once a minute.

Because of the object abstractions in this gem, some find it difficult to test API responses vis the console. To ease such console work, a 'console harness' was developed that provides several affordances to exploratory development.

Create a new harness in the console via

h = SolidusBactracs::ConsoleHarness.new

The easiest way to test the API, seeing both the output of the shipment when serialized as a XML SOAP request, and the result from the Bactracs API.

h.try_one

or try a few

h.try_batch(4)

maybe you have a shipment with particular issues, e.g. shipment number H123456789

h.shipment_number('H123456789')

h.try_one(h.shipment_number('H123456789'))

.shipment_number retries that shipment from the scope of available h.shipments.

If that was successful, you may find your list of shipments has one or more shipments that are already synced

h.shipments.size # => 7
h.refresh
h.shipments.size # => 6

You can set where in the recordset you want to continue trying from

h.cursor = 5
h.try_one

You can also change the default batch size

h.batch = 10
h.try_batch
# output from 10 runs, if not errors occur

Several deeply-nested objects are exposed for convenience

• runner
• syncer
• sync (job)

h.serialize(shipment)
# see the output of serialization

h.runner.authenticated_call(shipment: h.shipments[0], serializer: h.syncer.client.shipment_serializer)

Remember that you can monkey patch code in the console, to test the improvement the harness or the gem itself.

First bundle your dependencies, then run bin/rake. bin/rake will default to building the dummy app if it does not exist, then it will run specs. The dummy app can be regenerated by using bin/rake extension:test_app.

bin/rake

To run Rubocop static code analysis run

bundle exec rubocop

When testing your application's integration with this extension you may use its factories. Simply add this require statement to your spec/spec_helper.rb:

require 'solidus_shipstation/testing_support/factories'

Or, if you are using FactoryBot.definition_file_paths, you can load Solidus core factories along with this extension's factories using this statement:

SolidusDevSupport::TestingSupport::Factories.load_for(SolidusShipstation::Engine)

To run this extension in a sandboxed Solidus application, you can run bin/sandbox. The path for the sandbox app is ./sandbox and bin/rails will forward any Rails commands to sandbox/bin/rails.

Here's an example:

$ bin/rails server
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
* Listening on tcp://127.0.0.1:3000
Use Ctrl-C to stop

Before and after releases the changelog should be updated to reflect the up-to-date status of the project:

bin/rake changelog
git add CHANGELOG.md
git commit -m "Update the changelog"
