We have a flow for a client which does this. To make it work, after updating the data through other flows, we hit the “sync all to the collection” webhook.
We then instruct the user to “republish” the changes by hitting a button within the UI that triggers the WeWeb “publish project” hook.
However, as of late November, WeWeb deprecated the ability to see this “publish project” webhook within the UI. Luckily, the webhook still works and the client still has this functionality. They republish the data programmatically several times a week.
The last update I heard from @Quentin was that WeWeb would bring this feature back after deprecating the current functionality:
At the moment we don’t have any deprecated date for the hook, it’s being postponed. We’ll tell you in advance when this is the case.
For context, the current webhooks are being deprecated due to security concerns:
We will indeed depreciated those links in time as soon as possible for security reasons. Some people were using those links in a malicious way that could lead to break our publisher server. That’s why we had to do this change quickly for new users.
It’s possible you can do what you want with the setup I’ve described above—I would ask the WeWeb team to provide you with a link to the specific publish project hook.
