The discussion revolves around an issue with webhooks not functioning properly when moderator approval is enabled on a Discourse forum. jordan1909 encountered this problem, where webhooks on post or topic actions do not fire 99.9% of the time when moderator approval is enabled for users with a trust level (TL) of 2 or less. However, when a TL 3 user creates or edits a post, a webhook is triggered immediately.
simon tested this in their development environment and found that when a post is approved, it sends a Post Event webhook, and when a topic is approved, it sends a Topic and a Post Event webhook. jordan1909 shared screenshots of their webhook settings and confirmed that they are not seeing any errors in the events list.
simon asked if there were any errors in the Discourse logs, but jordan1909 found none. codinghorror inquired about the Discourse version, which is v1.9.0.beta17 +80.
jordan1909 performed tests, which showed that the issue is directly tied to topics that require approval. tgxworld ultimately fixed the issue in two commits to the Discourse GitHub repository.
I am using webhooks as I’ve mentioned in other threads here.
I’ve noticed a bug however in this and I’d like to understand if its by design or other.
On our install we use moderator approval on posts if the TL is 2 or less. In my testing however I have noticed that with this feature enabled, the webhooks on post or topic actions do not fire 99.9% of the time.
The biggest confusion for me is a few randomly fire but the bulk majority do not. I could potentially wrap my head around all not going or all going but a few here or there going and the rest not is confusing me.
Can anyone think of a reason webhooks wouldn’t fire when we approve moderated posts? I’ve tried all variations including send me everything to no success.
I was testing this in my development environment yesterday. When a post is approved it is sending a Post Event webhook, when a topic is approved it is sending a Topic and a Post Event webhook. This is working consistently for me. Are you seeing any errors in the events list for the webhook?
Sorry for the delay, I went afk for the holidays. I am still able to replicate this. When I get a chance I will make a quick video in the hopes someone spots a mistake.
Basically nothing is being triggered after approving topic. I am seeing no errors in the events list for the webhook either.
As you can see below I have pretty much set it to send me everything though I have tried limiting to just topic and post actions as well.
When I checked today the last webhook event that executed since 12/22 was for a ping that I sent using the ping button. Though the site has been pretty active since then.
When I can I will create a video of this in action. In the hopes someone has an idea why they are missing.
Literally nothing, its almost as if they aren’t enabled but they definitely are. I can actually replicate this in my development and production environments.
I was thinking that the issue was the webhook not being sent after a post or topic is approved, but it sounds as though the issue is affecting all webhook events on your forum. What happens when a TL 3 user creates or edits a post? If you reset the moderator approval settings to their defaults, does the problem go away?
If a user of TL 3 or higher creates or edits a post a webhook is triggered immediately. If I reset moderator approval it does in fact go away. So it seems to be directly tied into topics that require approval.
