Webhook subscription getting 502 responses



I’m trying to setup webhook subscriptions, but when I test a subscription with my url I get “ Something's not quite right. Are you sure this is the correct URL?”. I have activated the subscription and webhooks monitoring shows HTTP 502 responses, but our application doesn’t show the attempts in the logs.

When I use Postman to try the url, I get a HTTP 200 response and the http request does come up in the logs.


Hi @Weij,

I'd like to take a closer look at the logs. Can you share a link to the app in your developer account?


Hi @Isaac_Takushi,

Thanks for looking into this, here's the link: https://app.hubspot.com/developer/4959984/application/181495.


Hi @Isaac_Takushi,

Did you already have a look at the logs? The 502 is currently blocking my further progress, so I hope you can have a look at it soon.


We decided to create a workaround with another server which doesn't give the 502 response, and we'll forward the request from there.


Apologies for the delayed response, @Weij. Sounds good; since you made the change, I only see 200s in your logs.
