• API Docs
• Examples

Note on v1 and breaking changes

If migrating from a previous version of the library, there was a large refactor with breaking changes released to address some design issues with the library. See the migration guide for steps on how to migrate to the latest version.

This is recommended for all users.

Quickstart

Construct a new Recurly client, then use the various services on the client to access different parts of the Recurly API. For example:

client := recurly.NewClient("your-subdomain", "APIKEY")

// Retrieve an account
a, err := client.Accounts.Get(context.Background(), "1")

Examples and How To

Please go through examples for detailed examples of using this package.

The examples explain important cases like:

• Null Types
• Error Handling
• Get Methods
• Pagination

Here are a few snippets to demonstrate library usage.

Create Account

account, err := client.Accounts.Create(ctx, recurly.Account{
    Code: "1",
    FirstName: "Verena",
    LastName: "Example",
    Email: "verena@example.com",
})

NOTE: An account can also be created along a subscription by embedding the account in the subscription during creation. The purchases API also supports this, and likely other endpoints. See Recurly's documentation for details.

Get Account

account, err := client.Accounts.Get(ctx, "1")
if err != nil {
    return err
} else if account == nil {
    // account not found
    // Note: this nil, nil response on 404s is unique to Get() methods
    // See GoDoc for details.
}

Create Billing Info

// Using token obtained with recurly.js
// If you want to set billing info directly, omit the token and set the
// corresponding fields on the recurly.Billing struct.
billing, err := client.Billing.Create("1", recurly.Billing{
    Token: token,
})

NOTE: See the error handling section in GoDoc for how to handle transaction errors

Creating Purchases

purchase, err := c.Client.Purchases.Create(ctx, recurly.Purchase{
    Account: recurly.Account{
	    Code: "1",
    },
    Adjustments: []recurly.Adjustment{{
	    UnitAmountInCents: recurly.NewInt(100),
	    Description:       "Purchase Description",
	    ProductCode:       "product_code",
    }},
    CollectionMethod: recurly.CollectionMethodAutomatic,
    Currency:         "USD",
})
if err != nil {
    // NOTE: See GoDoc for how to handle failed transaction errors
}

NOTE: The purchases API supports subscriptions, adjustments, shipping addresses, shipping fees, and more. This is one of many possible examples. See the underlying structs and Recurly's documentation for more info.

Creating Subscriptions

subscription, err := client.Subscriptions.Create(ctx, recurly.NewSubscription{
    PlanCode: "gold",
    Currency: "USD",
    Account: recurly.Account{
        // Note: Set the Code for an existing account
        // To create a new account, omit Code but provide other fields
    },
})
if err != nil {
    // NOTE: See GoDoc for how to handle failed transaction errors
    return err
}

NOTE: Recurly offers several other ways to create subscriptions, often embedded within other requests (such as the Purchases.Create() call). See Recurly's documentation for more details.

Webhooks

This library supports webhooks via the webhooks sub package.

The usage is to parse the webhook from a reader, then use a switch statement to determine the type of webhook received.

// import "github.com/blacklightcms/recurly/webhooks"

hook, err := webhooks.Parse(r)
if e, ok := err.(*webhooks.ErrUnknownNotification); ok {
    // e.Name() holds the name of the notification
} else if err != nil {
    // all other errors
}

// Use a switch statement to determine the type of webhook received.
switch h := hook.(type) {
case *webhooks.AccountNotification:
    // h.Account
case *webhooks.PaymentNotification:
    // h.Account
    // h.Transaction
case *webhooks.SubscriptionNotification:
    // h.Account
    // h.Subscription
default:
    // webhook not listed above
}

Testing

Once you've imported this library into your application, you will want to add tests.

Internally this library sets up a test HTTPs server and validates methods, paths, query strings, request body, and returns XML. You will not need to worry about those internals when testing your own code that uses this library.

Instead we recommend using the mock package. The mock package provides mocks for all of the different services in this library.

For examples of how to test your code using mocks, visit the GoDoc examples.

NOTE: If you need to go beyond mocks and test requests/responses, testing.go exports TestServer. This is how the library tests itself. See the GoDoc or the *_test.go files for usage examples.

Contributing

We use dep for dependency management. If you do not have it installed, see the installation instructions.

To contribute: fork and clone the repository, cd into the directory, and run:

dep ensure

That will ensure you have google/go-cmp which is used to run tests.

If you plan on submitting a patch, please write tests for it.
