with my AppSID and Appkey

but alwayes i received an error parsing error

Hi Ossama,

Thank you for contacting support. It appears as you’re not signing URI before the REST API call. Please make sure that you’re concatenating URI with appSID and signature parameters as follows:

http://api.aspose.com/v1.1/barcode/generate?text=Barcode%20Text%20Here&type=DataMatrix&format=PNG&appSID=***********&signature=*******************

Sign method code is documented there:

http://www.aspose.com/docs/display/rest/REST+API+Methods

Please refer to the following REST API page:

In case, this does not help then please provide us your sample code in this forum thread. We’ll take a closer look and guide you accordingly.
