Webhook in workflows not working ("Retry")

[willvitt]

Hey everyone! 

So, about a month ago I was succesfully able to use a webhook in a wokflow to communicate with an endpoint on our side, the JSON worked out and everything was ok.

We did run into some SSL issues a couple weeks ago (not related to Hubspot), but everything seems to be sorted out by now,  except for the webhooks not working. When I go to the history of the workflow, it shows that the webhook to our endpoint could not be completed and will retry soon.

There's no response even though our endpoint does print out a message when it's complete.  POSTMAN requests does reach the endpoint and works properly...

Does anybody have any idea on what could be the problem? I've been trying everything I can think of and still no success 😞 

Thanks in advance!

Hey @willvitt,

On my end, when I tried to POST the deal request data of deal 'FAROFA' to the Webhook url in question on Postman, I'm seeing the following error:

In this case, could you share with me:

1. The implementation of the success Postman request to the Webhook url in question

2. A screenshot of the success request

3. The portal ID that the workflow is on

4. The workflow name

Hey Wendy, thanks for the reply!

I see... before I do that can you try something out for me then? 

This happened to me when I first tried, it's what led me to believe that the problem is in our server. Would you please do what postman says in the second line and disable the SSL verification? If it works after doing that, the problem MUST be on our end right?

I don't know what happened, for the first time I used postman on this endpoint it wouldn't work as well, I had the same problem as you did, but now I use SSL verification and it's working. Maybe it's something related to cache? I don't know...

Hey @willvitt,

Once I turned off the SSL verification settings, it works just fine. Checking out SSL labs, I noticed that the server's certificate chain is incomplete. This is likely why when I POST to the endpoint, I'm not getting any response. 

In this case, your team would need to fix the SSL certificate issue in order for HubSpot to successfully POST data to your endpoint.

Heya Wendy! Thank you so much for the answer!

I just needed official word that my code is running fine so that I could redirect the issue to our Server Admins. They're already contacting our provider to get the issue solved.

Thank you so much for the attention!
