Hi @Harshith (Airbyte) thanks for your reply and sorry for coming back so late. I've missed the notification. Unfortunately Airbyte Cloud is not an option for us. One reason is that we are in Europe.
One example on where it is really difficult to find information, would be the Facebook Pages connector. The docs show how to create a short-living API key, which is not at all useful as it's only valid for 60 minutes. There is a reference to the possibility to create a long-living key, but with no further information. After researching this for a while, I'm still not able to create one. As far as I understand this long-lived key can only be generated from an app that I would have to build for this sole purpose. This is probably more of a Facebook problem, but it doesn't help that the Airbyte docs just leave it at that. Do you maybe have more information on how to generate a long-living key for the Fb page connector?
