question

Hello Jamie,

I hope you have been referring to the steps mentioned here.
1. Can I know what is your sandbox developer account id?
2. Can I also know what is your call back URL that you are configuring?

3. What is the app name/UUID for which you are trying to configure the webhook?
NOTE:
Webhooks require a publicly accessible endpoint (localhost alone will not work). You must have a simple web server running on your machine that can receive a webhook setup request and verification code.
If you are having localhost, you can use one of the following tools to expose your localhost for testing:

• ngrok: Connects your local server to a public endpoint (http://subdomain.ngrok.com)
• Pagekite: Syncs your local server to a public endpoint (yourname.pagekite.me) (requires Python)

HI - thanks for the reply - I do have a publicly available endpoint - it's https://www.pcsoweb.com/pcsoauctionapi/Auction

DevID: 9B6P2EVJXYVEC

Appname is PCSOAUCTIONSTEST / 0FW4W7MRPG9JR

Maybe there's some sample C# .net Core webhook code I could look at and get some ideas?

Hi Jamie, I still feel there is some issue with your webhook callback URL server configuration. I tried to do this from my side and I see "Unable to reach the callback URL message" meaning which our POST request is not even reaching your server. Can you get any kind of logs on your server (https://www.pcsoweb.com/pcsoauctionapi/Auction) side to see if you receiving this POST request at all?
Can you also provide a minimum, reproducible example of your server's webhook callback handler? what does your configuration look like?
We do not provide any code snippets or examples to set this up, but searching in our Clover community forum should help you I believe. There have been people asking this same question about this error and they have also posted their code samples.

Ohh I am sure it's on my end - I just can't figure out what is wrong... I have a simple API set up to receive a post at my end point and I can get to it from outside my network, so I think it's alive but so far I can't get the verification to happen

I have searched the community but didn't find any answers - but I will search again

OK - so I have decided to get things set up using a mock service - I have verified the endpoint and set to receive all notifications - but when I do a checkout I don't get any notifications to my end point

https://pcsoclovertest.free.beeceptor.com

If I make any changes to my Hosted Checkout - I get a notification of the change - but no payment notifications...

Ideas?

Started working this morning and things were working as expected so I'm good for now I think

Jamie, Glad that you got it working.

Hi - back again!

OK so I had set up things to work with beeceptor and so that all worked - now I am trying again to pass the webhook directly to my servers endpoint and the verification still cannot see my endpoint

I can post to my endpoint through reqbin service so I know it's publicly available and working

all I get from the verification "Unable to reach callback URL" but I know for a fact that it's reachable

what can I do to get a better error message?

Seems the request is failing somewhere between my Firewall and WAF - I've got my network guys investigating but at least I DO see the traffic from the sandbox... stay tuned!
