See more GMail REST API Examples

Demonstrates how to get a list of message IDs in a GMail mailbox. The "userId" can be either the user's email address or the special value "me" to indicate the authenticated user. Go

    success := false

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

    http.SetAuthToken("ACCESS_TOKEN")

        http.DisposeHttp()
        resp.DisposeHttpResponse()
        return

    fmt.Println("Response Status Code: ", resp.StatusCode())

    jsonResponse := chilkat.NewJsonObject()
    jsonResponse.Load(resp.BodyStr())
    jsonResponse.SetEmitCompact(false)
    fmt.Println(*jsonResponse.Emit())
