Can I delete just the activities from a single Garmin device from my Garmin Connect account?

THanks    i ahve the following error - Is needed to write "Device_5UH21487X"  or just "5UH21487X"

Traceback (most recent call last):
File "C:\Users\XxX\Documents\gc-deletebydevice.py", line 142, in <module>
DEVICEID=int(DEVICEID)
^^^^^^^^^^^^^
ValueError: invalid literal for int() with base 10: '5UH21487X'
Press ENTER to exit.

Hey, last time I checked the device ID is just a number (no letters or special characters.) Which method did you use to obtain the device ID?

EDIT: I noticed that my bookmarklet script for obtaining the device ID from a Connect activity no longer works. I'll have to fix it.

EDIT: I've updated my original comment to fix the device ID script:

WillNorthYork Thanks for the code. HTTP 403 error forbidden when loading activity list.

Like others here, I'm so grateful to @WillNorthYork for working on a solution to delete all workouts from a given device. I tried to help somebody download a track, without thinking of the consequences... However, I'm getting the Error 402 Payment Required when I run the Python script. I can see that the previous fix is in the script "ACTIVITY_LIST = http_req(ACLISTURL, None,  { 'nk': 'NT' }) but it doesn't seem to work anymore... Any chance of another update, please?!

Updated F12 → Console script

• set limit=2 as needed (latest activities)
• replace !!!DEVICE_ID!!! (number from device's settings link)
  
• setTimeout 5000 is wait time

Run search script and check if prints correct results:

h={
 'DI-Backend':'connectapi.garmin.com',
 'Authorization':'Bearer '+JSON.parse(localStorage.token).access_token
}

jQuery.ajax({
 headers: h,
 url: 'https://connect.garmin.com/activitylist-service/activities/search/activities?limit=2',
 success: all => {
  t=0
  all.filter(a=>a.deviceId===!!!DEVICE_ID!!!).forEach(async a=>{
   await new Promise(s=>setTimeout(s,t+=5000))
   console.dir(a.activityId, a.activityName, a.startTimeLocal)
  })
 }
})

Add delete request inside the loop, new line after console.dir:

fetch('https://connect.garmin.com/activity-service/activity/' + a.activityId,
{
 'headers': {...h, 'X-HTTP-Method-Override': 'DELETE'},
 'method': 'POST'
})

To be safe, export all activities: garmin.com → Profile → Manage Data.

Thanks WillNorthYork for the ongoing work. I'm getting similar errors to Frans

First line reads
File "C:\####\Downloads\gc-deletebydevice.py", line 260, in <module>
LOGIN_RESPONSE = http_req(URL_GC_LOGIN + '#', urllib.parse.urlencode(POST_DATA), headers).decode()

Then the same errors on lines 107, 521, 630, 559, 492, & 639

Then the last line reads
urllib.error.HTTPError: HTTP Error 401: Unauthorized

If there's an update I'd love to be able to remove the data I now have from another user.

Much appreciated
Patrick

I get a similar error. WillNorthYork 

this helped me a lot. Now I would need something equivalent for Strava! :P
