go-xero is a Go client library for accessing the Xero API.
The go-xero library does not directly handle authentication.
Instead, when creating a new client, pass an http.Client that can handle authentication for you.
The easiest and recommended way to do this is using the oauth2 library,
but you can always use any other library that provides an http.Client.
Note that a XERO_TENANT_ID is required creating the Xero client instance.
If you have an OAuth2 XERO_ACCESS_TOKEN, you can use it with the oauth2 library using:
import (
"context"
"fmt"
"golang.org/x/oauth2"
"github.com/ezerw/go-xero"
)
func main() {
tokenSource := oauth2.StaticTokenSource(
&oauth2.Token{AccessToken: "ACCESS_TOKEN"}
)
ctx := context.Background()
httpClient := oauth2.NewClient(ctx, tokenSource)
xeroClient := xero.NewClient(httpClient, "XERO_TENANT_ID")
}
