### Show form entries on a Google Map in WordPress with [GravityView Maps!](https://www.gravitykit.com/products/maps/)

This article is about GravityView, the best way to display entries on a map in WordPress. It geocodes and displays [Gravity Forms](https://www.gravitykit.com/gravityforms) form submissions on a map.

![Google Maps JavaScript API RefererNotAllowedMapError; site URL not authorized, link to error documentation provided](https://www.gravitykit.com/wp-content/uploads/2025/10/file-19YsWRKIFL-scaled.png)If your map is not displaying and your browser console shows the  **"Google Maps JavaScript API error: RefererNotAllowedMapError"** it means the URL loading the Maps JavaScript API is not on the list of allowed referrers. Please check the referrer settings of your API key in the [Google Cloud Platform Console](https://cloud.google.com/console/google/maps-apis/overview)

## 1. Remove restrictions on the API key to debug

Removing any restrictions can help identify whether they're causing unexpected issues.

First, go to the [Credentials page of your Google Cloud Platform Console](https://console.cloud.google.com/google/maps-apis/credentials).

If you see a Maps API key under the "API Keys" header, click on the name of it to edit:

### For "Application restrictions", set to "None"

![Application restrictions options: None selected, Websites, IP addresses, Android apps, iOS apps](https://www.gravitykit.com/wp-content/uploads/2025/10/file-SZajbaecCT.png)

### Under "API restrictions", set to "Don't restrict key"

### Click Save

![Save and Cancel buttons with a note on settings delay](https://www.gravitykit.com/wp-content/uploads/2025/10/file-Lfx86tYGhc.png)**Please note, It can take up to 5 minutes for your new settings to take effect**, so you might have to wait a few minutes before refreshing the View and seeing the map.

## 2. Wait five minutes ⏲️😒

## 3. If it works, you have identified that the referrer is the issue 👍

**Don't stop now!** You won't want to leave the "API restrictions" and "Application restrictions" settings there; this will mean that others will be able to use your Maps API key anywhere, potentially costing you money.

## Now, we restore an "Application restriction" setting

- Set "Application restriction" to "Websites"
    
    ![Application restrictions options with "Websites" selected](https://www.gravitykit.com/wp-content/uploads/2025/10/file-13X5DRaWw9.png)
- Click "+ Add"
    
    ![Website restrictions section showing how to add site restrictions for an API key](https://www.gravitykit.com/wp-content/uploads/2025/10/file-x7yYRcjyfH.png)
- Set "Referrer" to **\*.yoursite.com/\***
    
    Make sure to replace "yoursite.com" with your domain (without www.!). This will allow the API to run on all the variations of your website (www.example.com, example.com, subdomain.example.com).
    
    ![Dialog box to add a website with input field for domain and buttons for Cancel and Done](https://www.gravitykit.com/wp-content/uploads/2025/10/file-mFBicANok3.png)
- If you have another site you want the maps to work on, click on "Add" button again to add another site.
- Save the settings again
- Wait five minutes
- If your site still doesn't work, try using the "IP addresses" restriction and entering the IP address of your server. Then (yep) wait another five minutes 🙄

## If everything still works on your site, set "API restrictions"

- Under "API restrictions", select "Restrict key"
- Check the "Geocoding API", "Maps Javascript API", and "Places API" checkboxes (see image below)
    
    ![API key restriction showing Maps, Places, and Geocoding APIs selected](https://www.gravitykit.com/wp-content/uploads/2025/10/file-M3buXmECr2.png)
- Save the settings
- Wait *another* five minutes! 😆

These settings should continue to work—if they don't, check all the boxes in the list, save, and wait five minutes. If it works again, then deselect one checkbox at a time and see which one makes things not work!
