Constructor Details

#initialize(auth_token, dev_id, app_id, cert_id, opt = {}) ⇒ API

Creates an eBay caller object.

You will need this object to make any API calls to eBay’s servers, so instantiation is required before you can use any other part of this library.

:call-seq:

new(auth_token, dev_id, app_id, cert_id)
new(auth_token, dev_id, app_id, cert_id, <em>:sandbox => true</em>)
new(auth_token, dev_id, app_id, cert_id, <em>:sandbox => false, :site_id => 3</em>)

The first four (4) arguments are required (all String’s):

auth_token = Your eBay Authentication Token
dev_id     = Your eBay Developer's ID
app_id     = Your eBay Application ID
cert_id    = Your eBay Certificate ID

The optional fifth argument is a hash where you can pass additional info to refine the caller object.

The key “sandbox”, for example:

eBay = EBay::API.new("my_auth_tok", "dev_id", "cert_id", "app_id", :sandbox => true)

creates a caller that works with the eBay “sandbox” environment. By default, the “live” environment is used.

You may also pass the key “site_id” to specify calls to be routed to international or special (e.g. “eBay Motors”) sites.
