Example JSON service request
You need a valid Access Token before accessing the 2BA web services.
- one time: Acquire the Refresh- and Access Token using OAuth2 Flow1 (Resource Owner Password Credentials Grant) or OAuth2 Flow2 (Authorization Code). Store the Tokens.
- continuously: Only(!) retrieve the access token if expired using the Refresh Token service (Refresh Access Token Service). Store the Access Token.
- Invoke the desired service, supplying the Access Token in the request header:
C# code example
<br>private void GetProductJson()
{
var request = (HttpWebRequest)WebRequest.Create(GlobalVariables.ResourceServer + "/json/product/details/" + this.txtGTIN.Text);
request.Method = "GET";
request.Headers.Add("Authorization", "Bearer " + _accessToken);
var response = (HttpWebResponse)request.GetResponse();
// Use your own preferred JSON parser here.
XmlReader reader = JsonReaderWriterFactory.CreateJsonReader(response.GetResponseStream(), new XmlDictionaryReaderQuotas());
var root = XElement.Load(reader);
// The fields we'd like to extract
var id = root.XPathSelectElement("//ID");
var manufacturerGLN = root.XPathSelectElement("//ManufacturerGLN");
var manufacturerName = root.XPathSelectElement("//ManufacturerName");
txtId.Text = (id == null) ? null : id.Value;
txtManufacturerGLN.Text = (manufacturerGLN == null) ? null : manufacturerGLN.Value;
txtManufacturerName.Text = (manufacturerName == null) ? null : manufacturerName.Value;
}
