Webhooks and vpn

Hello,

Our app is behind company VPN, and we're looking for ways to have the webhook mechanism working. We tried whitelisting some IPs based on this link but after doing that only the verification request seems to work... Additional file changes / modifications are not sent as notifications, although there are no errors in the App Console. Any suggestions ?

Thanks,

Victor VLAD

Hey @victorvlad, webhook verification only confirms Dropbox can reach your endpoint for the initial GET request. File change notifications are sent as HTTPS POST requests, and they’re only sent for accounts that have actually linked to your API app via OAuth and granted the required permissions (for scoped apps, that includes files.metadata.read).

If your app is behind a VPN/firewall, please also make sure inbound POST traffic is allowed to the same URL and that your handler returns HTTP 200 within 10 seconds. If you can’t make the endpoint publicly reachable outside the VPN, you may want to use cursor polling or /files/list_folder/longpoll instead.

There's a thread in the community with a similar issue that I grabbed some of this info from, check it out.

Yes, I added a cron for the cursor polling, so instead of getting the webhook we're proactively checking for changes. Thanks.
