Question

Webhook not returning all data from Unbounce form

Zapier novice here, needing help! I wrote HTML/JS code for a form in Unbounce and want to send all data submitted to an email. The form has up to 21 fields but the email output only shows: 
{"phone": "1234567890", "email": "xxx@abc.com", "recruiterEmail": "xxx@gmail.com", "page": "https://unbounce.xxxxxxxxxxxxxxx.com/travel-request/", "querystring": {}} 

Is this a problem with the form code not pushing all the data fields or a problem with the webhook not catching all of them? 

Secondly, do I need a formatting step to make the output print in readable form in the email?

Any suggestions appreciated! Thank you.

Hi ​@BeverlyM! 👋

Zapier novice here, needing help! I wrote HTML/JS code for a form in Unbounce and want to send all data submitted to an email. The form has up to 21 fields but the email output only shows: 
{"phone": "1234567890", "email": "xxx@abc.com", "recruiterEmail": "xxx@gmail.com", "page": "https://unbounce.xxxxxxxxxxxxxxx.com/travel-request/", "querystring": {}} 

Is this a problem with the form code not pushing all the data fields or a problem with the webhook not catching all of them? 

For the test submission that was loaded into the Zap, did the missing fields all contain a value? Asking as sometimes if a field doesn’t contain a value it won’t be shown in the Zap.

Also, is there a difference between the type of fields that are coming through from Unbounce and those that aren’t? Just wondering if maybe it’s only certain kinds of fields that we’re receiving data for.

That said, worth checking that there isn’t an issue with the custom HTML/JS that’s sending the data to Zapier. Can you try updating the code so that it sends the data to something like Postman for example to see if it’s able to receive all the fields? That will help to identify if the issue is on Zapier’s end or if there’s something in the custom code that’s preventing it from sending all the field data. 

Secondly, do I need a formatting step to make the output print in readable form in the email?

Are you using the Catch Hook or Catch Hook Raw trigger? If it’s the latter that might be why it’s outputting it as just the raw unparsed JSON rather than as separate fields containing each value. The Catch Hook trigger would output all the values for the fields into separate fields for you to be able to map individually in the email action so you can format and display the form submission data however you need. So I’d suggest switching to use the Catch Hook if you’re using the raw version.

Hi ​@BeverlyM 

Instead of using a custom Webhook, try using the available Unbounce Zap app integration:

Glad to hear it's working ​@BeverlyM! 🎉 Do you mind sharing which approach fixed it? Would be super helpful for anyone else who runs into the same issue. 🙏

@SamB I found the Unbounce integration to be much easier, since my coding skills are quite limited. But I had trouble getting all the form fields to map (probably coding issues). Unfortunately, due to project deadlines, I had to resort to using a less attractive native form in WP. But that doesn’t reduce my gratitude for your kind assistance! 😊
