After you set up your Zap to send webhooks, they may not send in the way you expect. Learn how to troubleshoot if your webhooks that should be coming from Zapier aren’t showing up, or aren’t showing up the way you expect.
1. Inspect the webhook requests
If your requests aren’t making it to the desired destination as you’d expect, a third-party app that can receive requests can help you examine the requests to see if there’s anything about them that may prevent your app or site from receiving them properly.
For this purpose, Zapier recommends using something like RequestBin to inspect the payloads. This will help you understand what Zapier is sending, making it easier to adjust it to your liking.
You likely already have this set up, but you’ll need to select Webhooks as the action app. Assuming you would like to send a POST request, select POST as your action.
Next, you’ll need to fill in the URL field. Instead of filling in the URL you would like to send the POST to, you'll need to give Zapier the URL from RequestBin. To generate that:
1. Visit the RequestBin homepage and click Create a Request Bin.
2. Copy the Endpoint URL on the screen, which should look something like this: https://enfqolxilygu8.x.pipedream.net.
3. Paste that into the Webhook URL field in your Zap.
Now, you’ll go into your Zap, specifically the Test section for the Webhooks step, and test that out.
Go into your RequestBin - do you see that POST request show up?
If so, it’s likely that the site meant to catch your request isn’t able to process the data. Please take a look at the payload in RequestBin to see what may be tripping up your site.
If you’re not sure, move on to the next section.
2. Check if the webhook is configured correctly
You’ll need to make sure that you’ve configured the webhook in the format that your own system requires. Learn how to set up your webhook action in your Zap.
3. Try the custom request option
If you need differently structured (particularly nested) data, the best option is to try the Custom Request option, instead of the POST option. That allows you to type out JSON and other data formats directly, instead of Zapier formatting it for you.
If you’re still having trouble getting your Webhooks action step to send properly, particularly if your app requires OAuth or any other type of authentication than Basic Auth, it's recommended that you build an app on Zapier's developer platform, which provides much more nuance and configuration options.
Alternately, you can contact Zapier support to see if there is a better way to set up your Webhooks step.
