When I sleep in two phases, I can only access the data for the second phase of my sleep. Consequently, I cannot view my complete sleep data.

I can log into Garmin Connect normally, but third-party OAuth authentication is failing. Strava returns ‘Invalid Garmin credentials’ even after password reset.

OAuth failure despite correct login usually indicates authentication mismatch or token issues. Common causes include expired tokens, incorrect login method (Google/Facebook vs email), cached sessions, or revoked permissions—reconnect apps and reauthorize integration.

Hi! My Edge 530 froze during standby and the .FIT file is corrupt. Online sites can't fix it. Can anyone help?

I looked at your file, and there is no data in the file to recover which is why the online tools can not fix it.

RE: I am an iOS developer. When parsing a Fit file with a size of 570k bytes, the parsing time is too long, exceeding 10 seconds. The SDK used is FitSwiftKit

Ben FIT — Thu, 23 Apr 2026 17:09:51 GMT

The 21.201 release of the FIT Swift SDK includes performance updates to the decoder. Our testing shows a 5-20% decrease in the time to decode files. It depends on what data is present in the file. The most gains are with files that require a lot of component expansion during decoding.

However, my Android colleague only took less than 2 seconds when parsing with a single file.

I am really eager to need your immediate help。

Getting Developer Access

Hello,

I am pretty deep into developing an app, but I'm unable to request access to the developer program / APIs as the website is down.

Is there an email I can contact to submit the request?

RE: Getting Developer Access

6774048 — Thu, 23 Apr 2026 16:39:09 GMT

That's annoying. Sounds like that's their common response which is more of a nonresponse.

2131611 — Thu, 23 Apr 2026 12:17:10 GMT

I submitted an API request 7 weeks ago. I got an email that it would take up to 2 weeks, tried to followup but haven't receive any updates or heard back since.

Hi,

I submitted our API access request 7 weeks ago. Within a few days, I received an email stating that the request had been received and that the process would take up to two weeks. The message also mentioned not to send reminders.

How can I get update on the current status of the request? I did try sending one follow-up earlier but have not received a response.

The issue is most likely not your Garmin password itself, but a problem with the OAuth connection flow between Garmin Connect and Strava. This has been reported by multiple users recently, especially when trying to link accounts through the mobile app, where Strava may incorrectly show “invalid Garmin credentials” even though the Garmin login works normally.

Chris B — Tue, 21 Apr 2026 16:20:44 GMT

Similar to Alex I did get an email back from Garmin. They seem to be re-working / updating the program as a whole.
I did respond asking for some kind of timeline to help plan accordingly. Will update here if they share anything back.

Hey, I currently develop a fitness app for iOS and would like to get access to the module for live heartrate data in Garmin Connect to send the data to my app and show it there. Do you maybe know if and how this is possible? Best Regards Otto

RE: Add create FIT file capability to FIT Python SDK ?

4870762 — Tue, 21 Apr 2026 12:18:15 GMT

Python is widely used for data processing and automation, so having native FIT file creation support significantly improves the SDK’s usability.

Add create FIT file capability to FIT Python SDK ?

Daksol — Sun, 19 Feb 2023 12:00:32 GMT

From what I can see the existing Python module does not contain the functionality for writing a FIT file.

Are there any plans to extend the functionality offered by the "Garmin - FIT Python SDK" library?

Useful to have a Python routine to read a FIT file, make some changes, and save it again.

Within the modules for other languages (eg C++) that capability seems to be there. https://developer.garmin.com/fit/example-projects/cpp/

Thanks

Hi.

Is it possible to providea graph of for all time since the Garmin was first used?

In addition to the Monthly and Yearly Graphs, show a Max graph, or at least Date Ranges.

I'd be very keen to see how my stats look over the last six years since I first purchased it?

How do I access my .fit files

8985916 — Sat, 18 Apr 2026 13:40:54 GMT

So my watch died towards the end of my run and therefore the run didn't sync to my garmin connect account. I've read online that I might be able to recover it from a .fit file but I don't know how to find them on my computer. Can anyone help please?

RE: How do I access my .fit files

8985916 — Tue, 21 Apr 2026 05:29:05 GMT

I did charge my watch but nothing is showing up on my watch for the run which is why I asked for help in here

Persistent 429 on API login — account blocked for 48+ hours

ickerc — Tue, 21 Apr 2026 04:03:34 GMT

Hi, I'm building a personal training planning tool that reads my own Garmin Connect data (activities, daily wellness, sleep) using python-garminconnect v0.3.1.

After a few failed login attempts during initial setup, my account is now returning 429 on every API login attempt — for 48+ hours and counting. My account works fine on the web and mobile app. No MFA enabled. No rate-limit email from Garmin.

Error across all strategies:
- `portal+cffi`: Portal login returned 429. Cloudflare is blocking this request.
- `portal+requests`: HTTP 403
- `mobile+cffi`: HTTP Error 429
- `mobile+requests`: Login failed (429 Rate Limit)

I've tried different IPs (home WiFi + mobile hotspot) — same result. The block appears to be at the account level, not IP.

Has anyone found a workaround when in this blocked state?

Any help appreciated.

RE: Getting Developer Access

ickerc — Tue, 21 Apr 2026 03:52:43 GMT

Same here, I can do a manual masive download but not automated. I get a 429... Any ideas?

Using a dominant position in hardware to cut off API access and kill third-party software competition, precisely while launching your own paid alternative (Connect+). Under European antitrust law, using hardware dominance to monopolize a secondary market is a textbook "abuse of a dominant position". Furthermore, the EU Data Act (Reg 2023/2854) was literally drafted and passed to make this exact corporate tactic illegal.

RE: How do I access my .fit files

6774048 — Tue, 21 Apr 2026 01:08:38 GMT

The FIT files I know of reside on connect.garmin.com, so if yours didn't sync to Connect, then I'm not sure how to get it. Also, can't you just charge your watch?
