How do I get full messages and attachments from my Gmail inbox using an API?

I want to download an entire inbox (email body text and attachments) from my Gmail. Using message IDs, I can get Gmail.Message objects, but these only appear to contain snippets (about 200 characters).

For C#, is there a way to get the whole inbox in XML format using the Gmail API?

Looking at the API you would need to make a request to /users/me/threads then to users/me/threads/<id>within that response there is a body.data value that is base 64 encoded. I am not 100% sure with the c# API but i assume that you would do something like: 

var request = service.Users.Threads.List("me");

var labels = request.Execute().Threads;
foreach(var thread in lables){
    var threadReqeust = service.Users.Threads.Get("me", thread.Id);
    var data = threadReqeust.Execute();
    //you have your entire message now
}

(do take note that this is semi pusudo code, as i have not checked this with the gmail api)

(https://developers.google.com/gmail/api/v1/reference/users/threads/list) (https://developers.google.com/gmail/api/v1/reference/users/threads/get) "An attachment ID is present if the body data is contained in a separate attachment."

Another option is to always login with IMAP (using ImapX or equivalent), and collect data that way, but using the API would be better.

According to the documentation, you can use

GET https://www.googleapis.com/gmail/v1/users/userId/messages/id

Is this the call you are using? It says the default format is Full :

"full": Returns the full email message data with body content parsed in the payload field; the raw field is not used. (default)

For getting attachments you can try Users.messages.attachments :

GET https://www.googleapis.com/gmail/v1/users/userId/messages/messageId/attachments/id

But for this you will need the attachment ID. You may want to check the User.messages overview, which shows the available data, maybe you can try the Payload calls?

For gmail API please refer to https://developers.google.com/gmail/api/v1/reference/users/messages/list#parameters

HTTP request

GET https://www.googleapis.com/gmail/v1/users/userId/messages

Make sure you are applying correct authorization headers on your requests.
