Usage

A simple create & buy shipment example:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using EasyPost;
using Newtonsoft.Json;

namespace example
{
    class exampleClass
    {
        static async Task Main()
        {
            EasyPost.ClientManager.SetCurrent(Environment.GetEnvironmentVariable("EASYPOST_API_KEY"));

            Dictionary<string, object> fromAddress = new Dictionary<string, object>() {
                { "name", "Dr. Steve Brule" },
                { "street1", "417 Montgomery Street" },
                { "street2", "5th Floor" },
                { "city", "San Francisco" },
                { "state", "CA" },
                { "country", "US" },
                { "zip", "94104" },
                { "phone", "4153334444" }
            };

            Dictionary<string, object> toAddress = new Dictionary<string, object>() {
                { "company", "EasyPost" },
                { "street1", "417 Montgomery Street" },
                { "street2", "Floor 5" },
                { "city", "San Francisco" },
                { "state", "CA" },
                { "country", "US" },
                { "zip", "94104" },
                { "phone", "415-379-7678" }
            };

            Dictionary<string, object> parcel = new Dictionary<string, object>() {
                { "length", 8 },
                { "width", 6 },
                { "height", 5 },
                { "weight", 10 },
            }

            Shipment shipment = await Shipment.Create(new Dictionary<string, object>() {
                { "from_address", fromAddress },
                { "to_address", toAddress },
                { "parcel", parcel },
            });

            await shipment.Buy(shipment.LowestRate());

            Console.WriteLine(JsonConvert.SerializeObject(shipment, Formatting.Indented));
        }
    }
}

Configuration

Single API Key

If you are operating with a single EasyPost API key, during the initialization of your application add the following to configure EasyPost.

using EasyPost;

ClientManager.SetCurrent("ApiKey");

Multiple API Keys

If you are operating with multiple EasyPost API keys, or wish to delegate the construction of the client requests, configure the ClientManager with a delegate at application initialization.

using EasyPost;

ClientManager.SetCurrent(() => new Client(new ClientConfiguration("yourApiKeyHere")));

Warning about Threads

NOTE: The EasyPost .NET client library (in particular, the ClientManager global object) is not threadsafe; do not attempt to perform requests from multiple threads in parallel. This can be particularly problematic if using multiple API keys; make sure to always use a Mutex, Monitor, or other synchronization method to ensure that concurrent requests do not enter the EasyPost library from different threads.

Development

It is highly recommended to use a purpose-built IDE when working with this project such as Visual Studio. Most actions such as building, cleaning, and testing can be done via the GUI.

# Build project
make build

# Lint project
make lint

# Format project
make format

# Run tests (recommended to instead run via an IDE like Visual Studio)
EASYPOST_TEST_API_KEY=123... EASYPOST_PROD_API_KEY=123... make test

# Generate coverage reports
EASYPOST_TEST_API_KEY=123... EASYPOST_PROD_API_KEY=123... make coverage

# Run security analysis
make scan

NuGet Dependencies

The NuGet package dependencies for this project are listed in the .csproj files. This project uses NuGet package locks to keep specific versions of dependencies. The lock files will be used during NuGet restore, if present.

If you need to update or alter NuGet dependencies, delete the package.lock.json files first. They will be regenerated during the next restore.

Testing

The test suite in this project was specifically built to produce consistent results on every run, regardless of when they run or who is running them. This project uses EasyVCR to record and replay HTTP requests and responses via "cassettes". When the suite is run, the HTTP requests and responses for each test function will be saved to a cassette if they do not exist already and replayed from this saved file if they do, which saves the need to make live API calls on every test run.

Sensitive Data: We've made every attempt to include scrubbers for sensitive data when recording cassettes so that PII or sensitive info does not persist in version control; however, please ensure when recording or re-recording cassettes that prior to committing your changes, no PII or sensitive information gets persisted by inspecting the cassette.

Making Changes: If you make an addition to this project, the request/response will get recorded automatically for you if a _vcr.SetUpTest("testName"); is included on the test function. When making changes to this project, you'll need to re-record the associated cassette to force a new live API call for that test which will then record the request/response used on the next run.

Test Data: The test suite has been populated with various helpful fixtures that are available for use, each completely independent from a particular user with the exception of the USPS carrier account ID ( see Unit Test API Keys for more information) which has a fallback value of our internal testing user's ID. Some fixtures use hard-coded dates that may need to be incremented if cassettes get re-recorded (such as reports or pickups).

Unit Test API Keys

The following are required on every test run:

• EASYPOST_TEST_API_KEY
• EASYPOST_PROD_API_KEY

The following are required when you need to re-record cassettes for applicable tests (fallback values are used otherwise):

• USPS_CARRIER_ACCOUNT_ID (eg: one-call buying a shipment for non-EasyPost employees)
• REFERRAL_USER_PROD_API_KEY (eg: adding a credit card to a referral user)

Some tests may require a user with a particular set of enabled features such as a Partner user when creating referrals. We have attempted to call out these functions in their respective docstrings.

Test Coverage

Unit test coverage reports can be generated by running the generate_test_reports.sh Bash script from the root of this repository.

A report will be generated for each version of the library. Final reports will be stored in the coveragereport folder in the root of the repository following generation.

The script requires the following tools installed in your PATH:

• dotnet
• reportgenerator
