[SOLVED] API Access Denied (403) After Upgrading to Supporter

1

Hi Intervals.icu Team,

I recently upgraded to Supporter to access the API, but I’m getting a 403 error when trying to use it.

Details:

  • Athlete ID: i256066
  • API Key: 1puezkan06zdf895zb1yykkxm (generated after upgrading)
  • Error: HTTP 403 {“status”:403,“error”:“Access denied”}
  • Endpoint: /api/v1/athlete/i256066/activities
  • Time of error: 2026-02-23 17:14 UTC+8

Could you please help check if my Supporter status is properly activated for API access?

Thank you!

You need to keep your API key secret! I have just regenerated yours.

You can use 0 in place of the athlete ID. Try with curl with your API key in place of xxx below:

curl -u API_KEY:xxx 'http://localhost:8044/api/v1/athlete/0'

You do not need to be a supporter for API access, but thanks for subscribing.

Thanks much David!

That said I’m still getting 401 Unauthorized error with:
curl -u API_KEY: ‘https://intervals.icu/api/v1/athlete/0/activities’ - may i please check if the key is fully activated?

API_KEY in bold above is NOT your API-key. API_KEY is the user and it is the same for EVERYONE, it is this exact string!

So modify that by
curl -u API_KEY: “YOUR personal API-key” ‘https://intervals.icu/api/v1/athlete/0/activities’
