To find the Google Map API code that you are using in Magento Admin, you will need to follow these steps:
- Login to your Magento Admin panel.
- Navigate to Stores > Configuration.
- In the left-hand menu, select 'General' and then click on 'Google API'.
- Here you will see the API key that is being used for the Google Maps functionality on your Magento site.
- If you need to use this API key for another extension, you can copy the key and use it where required.
I hope this helps! Let me know if you have any further questions.
