I am new to Interfaces and i am trying to fill form fields in advance for an iframe - but it does not seam to work similarly to the script embed. I was following instructions from this article: 

https://help.zapier.com/hc/en-us/articles/18227509518861-Fill-form-fields-in-advance-in-Zapier-Interfaces#h_01HA4TJK3BAHDKVJPR45WSTDPA

 

I tried using the logic from the code snippet type, and apply it to the iframe, by manually adding query-params='' to the embed code, but it does not seam to work. 

 

Here is my sample page: 

https://new-interface-378cad.zapier.app/page

Here is my sample iframe embed:

<iframe src="https://interfaces.zapier.com/embed/page/cltkgtnpi0014132siszlbjs6?&allowQueryParams=true" query-params='field-25d1=test@test.com'; style='max-width: 900px; width: 100%; height: 500px;'></iframe>
 

Further question, in case there is a solution to have query-params working inside an iframe:

If i have a dropdown selection field, which takes pulls in options dynamically from a table, how do i need to specify the pre-appended value in the query param? Would it work if i write it exactly as in the table (e.g. “Spot A1”)? Or alternatively get for reference id from inside the table?

Further tested and figured it out, it should be added directly to the src url as follows:

  • &<field reference>=<value to prepopulate>
  • and replicate the same if multiple
  • &<second field reference>=<value to prepopulate>
  • &<third field reference>=<value to prepopulate>


Based on the example from my initial post:

<iframe src="https://interfaces.zapier.com/embed/page/cltkgtnpi0014132siszlbjs6?&allowQueryParams=true&field-25d1=test@test.com" style='max-width: 900px; width: 100%; height: 500px;'></iframe>

Would still need help with the “Further question” :

If i have a dropdown selection field, which takes pulls in options dynamically from a table, how do i need to specify the pre-appended value in the query param?

Thanks so much for sharing the solution you found here @Emi.Lian! 

To prefill a value in a dropdown field it should work in work in exactly the same way e.g. add &fieldname=fieldoption to the URL.

For example if the dropdown field was called “status” and you wanted to select the option “Pending” you’d add “&status=Pending” to the end of the current iframe src URL:
https://interfaces.zapier.com/embed/page/cltkgtnpi0014132siszlbjs6?&allowQueryParams=true&field-25d1=test@test.com&status=Pending

Can you give that a try and confirm whether that selects the correct dropdown field option?
