Hey all, two questions about API/webhooks: 1. Changing experiments Live and doing other changes to the experiments (in Analysis --> Experiments) doesn't trigger a webhook? Is there a way to make it trigger a webhook? 2. We're using the https://cdn.growthbook.io/config/ API to pull some experiment conf data but I can't find any documentation for that endpoint anymore. Will it still be supported going forward and what's the reason for removing it from the docs?

Hey everyone! I’ve got a question regarding a query string override for experiments. Previously GrowthBook supported forcing experiment variation via query string. The code is still there, but user is set as not in experiment when query string is present, so this does not influence feature value. My question is - is this an expected behaviour or a bug? I know about

setForcedFeatures

method, but I’m also interested in experiment forcing and not just a feature.

We wanted to use Growthbook to achieve an equivalent to what Google Optimize can do. It requires a little bit of wrangling, so I thought it might be helpful to share the full code we're using to do it Some of these bits are very specific to us of course, but should not require that much adjustment for other companies We've made a specific environment for Webflow, and a specific project just for redirects - to reduce the risk someone accidentally sets up the wrong kind of test. Also currently it's possible to apply to every page on your site, so might benefit from some extra filtering/rules

hi, i am using growthbook inside docker environment. i defined a test metric over trino db and when i ran the result experiment query, i got this error:

line 59:5: Column 'dimension' cannot be resolved

and here is my query:

-- test_metric_trino (binomial)

WITH __rawExperiment as ( SELECT user_id as user_id, timestamp as timestamp, experiment_id as experiment_id, variation_id as variation_id FROM hive.experiments.viewed_experiment ), __experiment as ( -- Viewed Experiment SELECT e.user_id as user_id, cast(e.variation_id as varchar) as variation, e.timestamp as conversion_start, e.timestamp + INTERVAL '72' hour as conversion_end FROM __rawExperiment e WHERE e.experiment_id = 'test_trino2' AND e.timestamp >= from_iso8601_timestamp('2022-05-24T075900.000Z') ), __metric as ( -- Metric (test_metric_trino) SELECT user_id as user_id, 1 as value, m.timestamp as conversion_start, m.timestamp as conversion_end FROM ( SELECT user_id, occurrence_timestamp as timestamp FROM hive.khabarchin.action_event WHERE event_id = 74 ) m WHERE m.timestamp >= from_iso8601_timestamp('2022-05-24T075900.000Z') ), __distinctUsers as ( -- One row per user/dimension SELECT e.user_id, 'All' as dimension, ( CASE WHEN count(distinct e.variation) > 1 THEN '__multiple__' ELSE max(e.variation) END ) as variation, MIN(e.conversion_start) as conversion_start, MIN(e.conversion_end) as conversion_end FROM __experiment e GROUP BY dimension, e.user_id ), __userMetric as ( -- Add in the aggregate metric value for each user SELECT d.variation, d.dimension, 1 as value FROM __distinctUsers d JOIN __metric m ON (m.user_id = d.user_id) WHERE m.conversion_start >= d.conversion_start AND m.conversion_start <= d.conversion_end GROUP BY variation, dimension, d.user_id ), __overallUsers as ( -- Number of users in each variation SELECT variation, dimension, COUNT(*) as users FROM __distinctUsers GROUP BY variation, dimension ), __stats as ( -- Sum all user metrics together to get a total per variation/dimension SELECT variation, dimension, COUNT(*) as count, AVG(value) as mean, STDDEV(value) as stddev FROM __userMetric GROUP BY variation, dimension ) SELECT s.variation, s.dimension, s.count, s.mean, s.stddev, u.users FROM __stats s JOIN __overallUsers u ON ( s.variation = u.variation AND s.dimension = u.dimension )

Hi everyone! I'm trying to use Growth Book android kotlin SDK. I just wanna know is there any way to use it on android SDK version 21 and above?

Hi, I'm having issues with the latest docker version - the logon page no longer loads properly and all the graphics are missing. I've reverted to Build: d66f04f (2022-05-20) which is working fine.

Hello! My project requires me to abstract the feature flag implementation logic and implement feature flag as a custom hook. I am not sure if the issue I am running into is caused by the fact that I’m trying to create a custom hook, or it has to do with my configuration of the app. In the

useEffect

in the image,

json

on line 194 is undefined. Hence, line 196 also failed since

json

is undefined. Is the undefiend json expected? If not, what would I need to do to resolve that? Than kyou.

Hey guys, is there a way to

archive

features. So you have a record of every feature. This would obviously be a logical delete, and the full delete is to get rid of any unnecessary junk.

Hi. starting yesterday I am getting

AuthenticationFailed

on backend connecting to mongodb. I am using this on kubernetes using this helm chart by @adventurous-vase-72101. I checked

MONGODB_ROOT_PASSWORD

env var for mongodb is same as what we use in

MONGODB_URI

. has there been any change in

growthbook/growthbook:latest

image?

how can I add an experiment that was more than 12 months ago?

Thanks for all the support in hitting 3k stars on GitHub! 🎉 https://twitter.com/growth_book/status/1529526940993933312

Is there any way to enable any sort of MFA for a Growthbook account? Thanks!

Is there a way to restrict GB UI users to specific environments?

If I have people who work on multiple different projects but use the same email address for those projects (consulting) how do they sign into the SaaS version of GB using the same email address across multiple projects? (Assuming not currently possible)

How long does it take after I updated the feature flag value on the portal for it to reflect on the UI? My setup is already manually recalling the api, but I am not seeing the flag values being updated. Thanks

Hello! First of all our team is loving Growthbook, thank you. I have an experiment where I split users by their id. What happens if for some reason I fail to provide id as an attribute to Growthboo?. In my tests I'm seeing that the user isn't assigned to any variation, wanted to confirm this.

Hi! I’ve opened an issue in github. I’ll appreciate it if you check!

Hey team, it looks like the behavior of webhooks has changed. Is there a way to make webhooks fire whenever feature definition changes, as the documentation specifies?

Hello 👋 I'm investigating GrowthBook for work, we're currently using LaunchDarkly but not very satisfied. Something we struggle with in LD is how to handle the mobile situation where we want to use the device OS as a condition, but potentially a single user may have multiple devices of varying OS. Targeting attributes look like they're tied to a single user ID, I assume (like LD) if that user logs into an Android device and then into an iOS device, only the latest call to

setAttributes

will be reflected. We ended up using a stable unique-per-device identifier as the user ID, but it makes LD pretty unpleasant to use. Is this something GrowthBook has come across? Do other people handle this situation differently? Would really appreciate any battle stories. 🙂

Hey. I'm trying to create an experiment from a feature, but hitting this error:

Hello everyone, I recently installed growthbook Self Hosting but I have no way to enter because I have no username or password, does anyone know how I can enter the application

Hello! I'm trying to import some existing experiment data into GrowthBook. I have both a

user_id

and

user_pseudo_id

identifier set up. It looks like the import is failing because the query that's auto-generated by GrowthBook to pull in experiment data has subbed in the

user_pseudo_id

name in the wrong spot. See thread for more details.

<!here> anyone deployed it with ingress in kubernetes..?? As backend and frond end are using different PORT 3000 and 3100 I am getting CORS error

<!here> Does Growthbook store data in DB related to assigned variation flag value to given user? like userId=123

inExperiment: true,
  variationId: 1,
  value: 'TEST_VAL_2',
  hashAttribute: 'id',
  hashValue: '333'

Does these information store in DB?

Is there a way for the

suspicious result

warning to still allow the actual % change? I totally understand not wanting to encourage making decisions based on faulty data, but just raising warning makes the user feel stuck in not being able to see how the numbers may be too unrealistic. It’s like saying “something is wrong here” without helping the person see what may seem wrong

Hi guys, been using the growth book at my org for the last few months and am quite amazed by its ease of use from a developer's perspective. I just wanted to know if there should also be sections in docs specified on how to use it in an SSR context, especially with frameworks like Next.js and Remix. ? The reason is, that I think it might help developers take the right approach based on their framework type. Considering the docs show the usage strictly on client which is not very suitable due to flickering/CLS/ blocking UI and that can be avoided easily if you have SSR react in some way... Maybe we can add a section in the context of the SSR application where essentially we do the same but on the server data fetcher logic and still pass the features list to the provider. One possible way in Next.js specific could be something along the lines of

export const getServerSideProps= async ()=>{
 const gbFeatures= await fetchGrowthbookFeatures();

 return {
  gbFeatures
 }

}

On my

_app.tsx

I did something or of sort

const growthbook = useMemo(()=>{
 return new Growthbook({
    features: pageProps?.gbFeatures?.features,
     attributes: ....// we can set them here as well
 })
},[pageProps])

useEffect(()=>{
  if( pageProps?.gbFeatures) return ;  // since SSR handled it

fetch('apiendpoint').then()//// the usual client approach as per doc
 
},[growthbook, pageProps?.gbFeatures?])

<GrowthbookProvider growthbook={growthbook}>{children}</GrowthbookProvider>

Any thoughts on this? Happy to contribute and raise a PR..

Hi GB! I have a question related to the capping functionality: When you set a capping for a metric, it is applied to the whole experiment period or is it daily? How can we know the time period for the capping? For instance if we want to cap the daily orders at 50, and we assign a metric that's a count of orders (with its timestamp) to an experiment that lasts two weeks, does it mean that a user that has more than 50 orders in the three weeks is going to be reset at 50? or that daily users in those three weeks are capped at 50? 👀 Thanks a lot!

Hello GB team, any recommendation on mongodb version to be used with Growthbook ? Thanks
