Developers & API

I use an R script to retrieve my personal activity data from Strava using the API. I use the following code, that, in the past, always gave me data on average and max heart rates, but now these have disappeared for some reason: while (TRUE) { req <- httr::GET( url = "https://www.strava.com/api/v3/athlete/activities", config = token, query = list(per_page = 200, page = page) ) # Convert JSON to dataframe activity_data <- fromJSON(content(req, as = "text"), flatten = TRUE) # Stop if no data found if (length(activity_data) == 0) {break} # Append data to dataframe if (nrow(df) == 0) {df <- activity_data} else { common_cols <- intersect(names(df), names(activity_data)) df <- rbind(df[, common_cols, drop = FALSE], activity_data[, common_cols, drop = FALSE])} # Turn to next page page <- page + 1}Anyone has an idea why the heart rate data is missing?

Hello colleagues,This is my first post here. In fact it's my first time ever when I reach to any community for help. So please have mercy 🙂 I tried to learn how to make API calls. I wanted to make call to Strava to fill my feed with dummy activity. But when I thought I made everything correctly here is an result:And I wonder If it's me who made something wrong or really It's bad luck?I will be greateful for your help,Lukasz  

Hi Strava Developer Support Team,I recently submitted a request to increase the API rate limit (Athlete Capacity) for my application.My app, "VietinBank Bắc Hà Nội - Happy run 2026", is strictly an internal application built to host a short-term, non-commercial running event celebrating our 75th company anniversary. We are expecting exactly 400 internal employees to participate.Due to a critical timeline, our official event launch is scheduled for tomorrow, June 6th. We are currently locked at the standard 10-user capacity, which completely blocks our employees from connecting their Strava accounts to our internal leaderboard.We fully comply with Strava's API guidelines and branding. I have attached screenshots/screencasts of the user flow and the "Connect with Strava" button for your quick review.App Details: Client ID: 255063 Requested Capacity: Extended Access (for ~400 users) Purpose: Internal leaderboard for a private company run. Could you please help us expedite the review p

Is there any way to check your submission? I want to see If I correctly applied for both?

Good morning,I'm wondering what best practice could be given regarding the usage of different Strava accounts for different environments. While searching the internet I read that Stava expects to have only one application using a client ID. Which would imply a different client ID per application, but also for the different environment in use.Currently I do local development, but I run a test and production server. So I use three client id's. Which becomes expensive if I need to pay for each of them. Or can it be bundled into one developer having a subscription?Thanks for your thoughts and answers.Pieterbas

If I tap to Routes or paid sub it's display an error. My acount (google)was a Russian before,  but right now it's Serbian. But Steava doesn't work properly. May be it's the reason?

Hello,I applied for Extended Access about two weeks ago but haven't received any response yet.My app details:Client ID: 166978 Category: DataImporterHow long does the Extended Access review usually take? Is there a way to check the status of my application?Thank you!

Given a user that has more than one gear for a specific sport, when an activity is registered through an external app (i.e. Garmin Conect), it will be imported with the default one, which makes the user update the gear field with the correct one.For example, let's say a cyclist has a mountain bike registered and a road bike. The mountain bike is set as default for cycling. The athlete registers a new activity with the road bike in Garmin Connect, which gets automatically imported into Strava as if it were roden with the mountain bike. After that, then the user logs into Strava and edits the activity to set the road bike instead of MTB as ridden.For a 3rd party application that is listening to the API webhooks, the final picture is that the activity was done with the mountain bike instead of the road bike, which is incorrect. This forces the application to make an additional call for each newly registered activity.Having a Webhook for this kind of activity update is something both Strav

I read through the activity documentation for the STRAVA API and do not see any fields to retrieve the participant IDs for other participants of a group run. Is this not in the API or is there another way to identify which participants complete activities together?  

I submitted two requests one week ago but have not received any response from the Strava team. My project is very urgent, so what can I do to get approval or who can I contact for support on this issue?

Currently, my personal Strava account is tied to the Developer API Application that I'm using for a running app I helped develop. I want to transfer this to a new developer taking over for me. How can I do this? I just emailed support.

i'm trying to do some analysis, and i'm working with the raw activities.csv, but the field "Activity ID" do not match any of the raw activity files that come with the bulk download (e.g. 3517781504.fit.gz, this number 3517781504 doesn't match any id in the .csv) . this make matching impossible.  how do you match raw .fit files to the activity ids?? 

Can you please update the clubs documentation at https://developers.strava.com/docs/reference/#api-Clubs. The data returned does not match the docs and there is some limit to the pagination effecting the number of activities that can be returned. Many users ran into both these issues and posted on the old Google groups.Hopefully when you document these it will become clear this endpoint needs to be improved as it's currently of very limited use.

Hi,I´m using `${STRAVA_API_URL}/clubs/${clubId}/group_events` where const STRAVA_API_URL = "https://www.strava.com/api/v3";It seems that the id of some of the club events is obfuscated and the last digits are replaced with zeroes, so that e.g. 3393591506183906380 becomes 3393591506183906300 in the result JSON.Why is this error introduced? 

Hey 👋 Recently started experimenting with API, and wanted to fetch watts stream for cycling to calculate different metrics on my own (1sec power, 10 sec power, 1 minute power, ...). Endpoint: https://developers.strava.com/docs/reference/#api-Streams-getActivityStreams What I noticed immediately upon fetching data, is that I was not able to match anyhow 1-sec best power. Strava app showed me 1-sec power around 600 watts for the ride, but when I fetched the stream - the highest number was around 270. I read about it a bit, learned that Strava might be downsampling on longer rides, but what feels weird is that this ride was 45-mins long, and my strava app even shows 15-sec power around 500. Now I’m left wondering if streams endpoint is of any use, since I can’t rely on the returned data. It’s not an isolated case, I encountered same issue on another activities I checked.  How I fetch the stream:url = f"{config.STRAVA_API_BASE}/activities/{activity_id}/streams" params = { 'keys'

Hi,I was wondering if anyone can help, I am having an issue trying to access my activity data for a dashboard I am building. I have tried using the refresh token given on my strava API application page and this results in a read_all_permission missing authorization error. I have seen a number of others have had this issue so I followed the fix they suggested:Using the address to approve and take the code from the resulting addressand using that method to get a different refresh token but instead of fixing the issue that then results in a 'refresh_token', 'code': 'invalid' response when I try to request an access token.Can anyone help?Thanks

Hello! I’m a Strava subscriber who organizes a local cycling club. I’ve created a club for it within Strava, but I want to push each week’s ride activity into Strava via the API. Is it possible to add write methods to the club activities API so each week I can have another system push that data to Strava? Thanks!

I am the developer of an application currently using the Strava API (Client ID:  159350.We believe we haven't reached the 100-athlete limit for development applications.Could you please help us verify our current usage, and if needed, grant a quota increase?This application is intended to help a small group of runners automatically track and analyze their activities via Google Sheets.Thank you in advance for your assistance!

Hello, We have a swimming app and have a limit at 999 for number of athletes allowed to connect. We reached this limit. How to get past it? How to raise the limit? Thanks a lot

Hello,I'm trying to load data from a segment `/api/v3/segments/[id]` that gives me a "Rate Limit Exceeded" error.However, the quota does not seems to be reached: I log the usage and I get something like: Instant usage: 75/600 - Daily usage: 4392/6000.I dig into the logs and it seems that it stopped working at half the quota, 3000/6000.Is there any other limitation I'm not aware of?

Hello everyone, I'am discovering the Strava API and i have already an issue with the fonctionnality "explore segments"This is my code :http get "https://www.strava.com/api/v3/segments/explore?bounds=[48.750242,5.116399597167978,48.79404419496171,5.216993164062509]&activity_type=riding" "Authorization: Bearer my_token"I ran it in the command prompt and none segments are found. Can you help me ?

Hey all, looking for some guidance from developers who have solved this problem or from the Strava team directly.I'm building a segment discovery app (Segment Sniper) that helps athletes find segments with beatable leaderboards for both cycling and running. One of the features I'm working on is alerting users when their KOM, QOM, or CR position is under threat or has been taken.The challenge is getting leaderboard data frequently enough to detect changes without blowing through the rate limits (200 requests per 15 minutes, 2,000 per day).Here's what I'm currently thinking:1. Using webhooks (POST /push_subscriptions) to detect when any of our users uploads a new activity. When a webhook fires, I check which segments overlap with that activity and refresh only those specific leaderboards. This avoids polling entirely for activity detection.2. For leaderboard monitoring on segments where our users hold positions, I'm batching GET /segments/{id}/leaderboard calls during off-peak hours and

https://developers.strava.com/docs/reference/#api-models-DetailedActivity states that a `best_efforts` field should be returned. Presumably this would be a subset of the `segment_efforts` collection, but I am not seeing it returned in any queries in order to verify this assumption. What are the conditions that result in an activity returning the `best_efforts` field? Is it a subset of `segment_efforts`? Or is it something else? The docs should be updated with this information.

New API Policy §5.3 prohibits using Strava Data in AI, including data "derived from" Strava Data.My app calculates CTL, ATL, TSB from activity summaries via my own algorithms. Raw Strava fields (HR, power, pace) never reach any AI model - already removed.But when I send "CTL=62, compliance=80%" to an LLM for coaching advice - does that count as "derived from"?This likely affects every training/coaching app using the API. Clear on raw data. Unclear on calculated metrics.Artur (Client ID: 186368, Motus)
