(C# UWP/WinRT) Xero Get Attachment (Download a Xero Attachment)

Demonstrates how to get the content of an attachment in Xero.

Note: This example requires Chilkat v9.5.0.64 or greater.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

// Note: Requires Chilkat v9.5.0.64 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Rest rest = new Chilkat.Rest();
bool success;

// Before sending REST API calls, the REST object needs to be
// initialized for OAuth1.
// See Xero 2-Legged OAuth1 Setup for sample code.

// Assuming the REST object's OAuth1 authenticator is setup, and the initial
// connection was made, we may now send REST HTTP requests..

// --------------------------------------------------------------
// First get a list of attachments for a given document (in this case a Receipt).

string endPoint = "Receipts";
string receiptID = "c4f40e59-c390-0001-caff-ce731c707d00";

int numReplaced = sbPath.Replace("{Endpoint}",endPoint);

string responseXml = await rest.FullRequestNoBodyAsync("GET",sbPath.GetAsString());
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// A 200 response is expected for actual success.
if (rest.ResponseStatusCode != 200) {
    Debug.WriteLine(responseXml);
    return;
}

// Examine the response.
Debug.WriteLine(responseXml);

// A sample response looks like this:
