We can use the latter to get our message count. The json response we get back includes two keys – one is a list of messages, while the other is the number of messages. Unread_count = messagesīy using is:inbox + ``is:unread we can get emails with both of those labels. messages = ers().messages().list(userId='me', q='is:inbox + is:unread').execute() The API allows you to place filters (such as userId='me') inside the call to list(), and one of them is a query string (denoted as q=. There’s a hidden label called “UNREAD” that’ll work nicely. How do we do that?Ĭheck out that screen capture above again. But we’re not interested in *all *email, just a subset. The one we need is, so we can get a list of messages (and then count them). It’s a nice tool, where you can browse through all the available API calls, and even try them out, all from within your browser. results = ers().labels().list(userId='me').execute()īut what do we change them to? To find out which API calls we need to make, we’ll delve into the APIs Explorer for the Gmail API. The following two lines got the list of labels above, and those are the ones we’ll change. Most of their script is just about authenticating to Gmail, so don’t touch any of that. We’ll just modify the sample script they provided. Once authenticated, their API gives you access to all kinds of useful info about your account. After you authenticate, their sample script prints a list of your email tags: Getting the Unread Mail Count Note the other languages on the left too, if you’d rather try one of those. #123 flash chat on raspberry pi 3 download#You download those numbers in a special file called “client_secret.json” and include it with your script, which in turn helps prove that the script is authorized to access your account.įollow their Python Quickstart. This process involves entering a few details on their side, and then they assign you some special numbers (a “client id” and a “client secret”). We can use the API to access messages or pretty much any other aspect of our email account. Google provides an API for connecting to most of their systems (including Gmail), along with tutorials to implement it in multiple languages (including Python). There’s another, more secure and stable, way to access a Gmail account. That’s okay… 2FA is a good thing, and we don’t want to disable that. #123 flash chat on raspberry pi 3 verification#The problem is that I have 2-Step Verification enabled, and the script can’t get past that. #123 flash chat on raspberry pi 3 password#Every time I tried a Python script I found, I’d get the following error: imaplib.error: Application-specific password required: (Failure) ![]() Gmail is the only service I use, so that’s the one I focused on.) Authenticating But understanding an API enough to properly implement it takes time, and I just didn’t have enough of it. (Note: At the beginning of the week, I thought I’d implement all three of those, to demonstrate how each works. Most of the major email services provide an API, including MS Office, Yahoo Mail, and Gmail. When a company provides an API, that means they’ve put real time and effort into exposing certain areas of their system to you (although you’ll still have to do some work of your own, as we’ll see), and you can access those systems in relative confidence that how you’re connecting won’t just change or break. These are commonly referred to as APIs, or application programming interfaces. The preferred option is to check whether your email provider has already provided an “official” way to connect to their system and retrieve data from it. ![]() #123 flash chat on raspberry pi 3 code#But what you can do will be extremely limited, and the code will be fragile. Do a quick search, and you’ll likely find scripts like this one where you just connect with your username, password and a few other pieces of info depending on who the provider is. We need to create a secure connection to our email provider, so we can find out when new mail arrives. The circuit will be extremely straight-forward, so let’s focus on the more difficult part first – connecting to an email service. The idea is to check for new email, and flash an LED when we get one. This week we’ll create an email notification system using the Raspberry Pi. ![]()
