xerogolang (deprecated as of April 2021)

Looking for OAuth 2.0?

This repository xerogolang was hand written for use with OAuth1.0a. For OAuth 2, we've moved to building next generation SDKs in an automated fashion using OpenAPI specifications.

OAuth 1.0a was officially deprecated on March 31, 2021. We've made the decision to archive xerogolang and not update to OAuth 2 as this is not inline with our strategy to automate the creation of them from OpenAPI specs.

Our official Golang OAuth2 SDK is development is on hold until we secure resources to get the code to MVP status.

In the meantime, we do have a golang example project that can help you authenticate and roll your own API calls without a full blown SDK.

What about updating xerogolang to OAuth 2.0?

We are devoting resources towards building and improving our new OAuth 2.0 SDKs which don't share a code base with this library. For those using xerogolang, you have the option of forking this repository and modifying it for future use.

This is the Xero Golang SDK for the Xero API.

Currently it only supports the Accounting API.

Xero App

You'll need to decide which type of Xero app you'll be building Private, Public, or Partner. Go to http://app.xero.com and login with your Xero user account to create an app.

Download Xero Golang SDK

Download the SDK using the following command:

$ go get github.com/XeroAPI/xerogolang

Configure

The Xero Golang SDK is easily configured using environment variables to configure values unique to your Application.

The following values need to be set:

XERO_KEY=Your_Consumer_Key
XERO_SECRET=Your_Consumer_Secret
XERO_USER_AGENT=Your_application_name

Find the Consumer_Key and Consumer_Secret you want to use at developer.xero.com under My Apps > Select App > OAuth Credentials.

You must also set a method - this must be either "public", "private", or "partner"

XERO_METHOD=public_private_or_partner

If you are using the "private" or "partner" method you'll also need a Private key path:

XERO_PRIVATE_KEY_PATH=/Path/to/your/privatekey.pem

We include an Example App (in this repo) built using Gorilla.

Example App

This repo includes an Example App mentioned above. The app contains examples of most of the functions available via the API.

To run the example app do the following:

$ cd xerogolang/example
$ go get -v
$ go build
$ ./example

Now open up your browser and go to http://localhost:3000 to see the example.

The example app uses a filesystem store for sessions - you will need to implement your own store when using this SDK within your own app. We recommend Gorilla Sessions

Data Endpoints

The Xero Golang SDK contains the Accounting package which has helper methods to perform (Create, Find, Update and Remove) actions on each endpoints and structs of each endpoint's response. If an endpoint does not have one of the methods then that method is not available on the endpoint. E.g. Branding Themes can only use Find methods because you cannot Create, Update, or Remove them via the API.

Create

Create can be called on structs that have been populated with data:

c := &Contacts{
  Contacts: []Contact{
    Contact{
      Name: "Cosmo Kramer",
    },
  },
}
r, err := c.Create(provider, session)

Find

Find is called either to get a single entity given an id:

i, err := accounting.FindInvoice(provider, session, id)

all entities from an endpoint:

i, err = accounting.FindInvoices(provider, session, nil)

all entities from an endpoint since a specific time:

i, err = accounting.FindInvoicesModifiedSince(provider, session, time.Now().Add(-24*time.Hour), nil)

all entities from an endpoint using paging:

querystringParameters := map[string]string{
  "page": 1,
}

i, err = accounting.FindInvoices(provider, session, querystringParameters)

all entities from an endpoint that match a given where clause:

querystringParameters := map[string]string{
  "where": "Contact.Name==\"Vanderlay Industries\"",
}

i, err = accounting.FindInvoices(provider, session, querystringParameters)

all entities from an endpoint in a particular order:

querystringParameters := map[string]string{
  "order": "DueDate",
}

i, err = accounting.FindInvoices(provider, session, querystringParameters)

all entities from an endpoint using a filter:

querystringParameters := map[string]string{
  "Statuses": "DRAFT,SUBMITTED",
}

i, err = accounting.FindInvoices(provider, session, querystringParameters)

a combination of all of the above:

querystringParameters := map[string]string{
  "page": 1,
  "where": "Contact.Name==\"Vanderlay Industries\"",
  "order": "DueDate",
  "Statuses": "DRAFT,SUBMITTED",
}

i, err = accounting.FindInvoicesModifiedSince(provider, session, time.Now().Add(-24*time.Hour), querystringParameters)

Update

Update can be called on a struct containing the data to update. You can only update one entity at a time though.

a, err := accounts.Update(provider, session)

Remove

Remove can be called to remove an entity if you provide an ID - it is not provided on all endpoints though.

t, err := RemoveTrackingCategory(provider, session, "trackingCategoryID")

Acknowledgement

The Xero golang SDK is extended from the great oauth work done by markbates' Goth and mrjones' oauth. We have added support for Xero a provider directly in goth as well so if for some reason you don't want models and methods you can use goth directly.

The gorilla web toolkit is used throughout this SDK and comes highly recommended.
