Access your meal tracking data stored in MyFitnessPal programatically
Hi,
I got an error when I enter myfitnesspal store-password my_username
Traceback (most recent call last):

I'd guess from what you've shown that the table the UI shows if you log-in using a browser is missing some of the columns?
I did just check what I get on my account, and it does look like the data is still being returned:
In [6]: c.get_date(2020, 11, 16).totals
Out[6]: {'calories': 871.0, 'carbohydrates': 65.0, 'fat': 37.0, 'protein': 79.0}
(you'll see that I'm sort of awful at tracking things :-|)
(noticed that I forgot to ping you)
In most cases, what this library does is scrape data right out of the webpage you see when you log-in to myfitnesspal
if there isn't some kind of identifier for the food item ID shown there, there isn't a way for us to figure one out
that isn't to say that there isn't such an ID in the page, though -- I'm just not aware of one being there
I'm actually not totally sure personally; that feature was a community contribution
you might have to do a little research to find out the answer
Oh, it's definitely broken today; the login request is getting an HTTP 406; so they've probably changed something about the POST data
ok; I just pushed up a (not-yet-released) fix for this to github; it looks like they might be doing some amount of user agent filtering
so I've just updated the login request to explicitly specify a user agent
Fix released as 1.16.2; hopefully the folks at MFP made those changes for reasons other than intentionally locking us out
Had to re-package the release (twice!) because of something mysteriously causing the wheel version of the package to be out-of-date (maybe the build directory wasn't cleared?); so it's actually fixed in 1.16.4
So I replaced the code with the one from the repo and it's working again.
I just downloaded the latest version of the library from pypi, and it does appear to have the changes I made in bb34f7291f117b3a6605b7591b8764cd38c655f6, so I'm not at all sure why you'd have to update the library manually right now
I've also tested the latest version on pypi and it works (i.e. no JSONDecodeError and I can see the day listing)
But, I did get a couple messages this week about folks having trouble using it, so I believe you; I'm just not sure I understand what might've went wrong; can you confirm that when you asked pypi to install, that it downloaded 1.16.4? (https://pypi.org/project/myfitnesspal/1.16.4/#files)

Hey everyone! I came across this project when I wanted to create my own iOS widgets for tracking my macros in MFP. This being in Python didn't help me directly, but I started up a mirror project in Swift at https://github.com/LePips/swift-myfitnesspal
Hi @coddingtonbear, I wanted to start by saying great work on the library, it's so great to be able to pull my data from myfitnesspal. I had a question which might be off-topic but I see that this library using parsing to get the data. I was just wondering if you ever looking into reverse engineering the private API (I am assuming here that the mobile apps use them)? Was there a reason you didn't go down that route?
That being said, I do see the
That being said, I do see the
BASE_API_URL variable so have I misunderstood and that this library actually uses the REST API?
@VikashKothary -- I hadn't actually considered what APIs the mobile apps might be using, but that's an excellent idea! Things are right now mostly relying on scraping the web UI because my original use case was pretty simple, and also relying on something as trivial as web scraping makes it at least possibly possible that somebody might be able to post a PR to fix the library were MFP to change their UI in a breaking way.
If we start using APIs that are more-difficult to introspect (I'm betting like 0.1% of folks would even know where to begin around setting up a MITM proxy), it means that more of the updating/fixing burden lands on a smaller fraction of folks
Re: this library & MFP -- it's mostly just scraping the visible web pages, but does rely on some reverse-engineered REST APIs that the web UI interacts with
