API Connector Pro
The free version of API Connector for Google Sheets enables up to 10 daily API requests, while the paid version allows more requests, scheduling, and some additional power features.

When you install this add-on, you will automatically enter a 7-day free trial that activates all features. After 7 days, you can choose to upgrade to a paid plan or continue using the free features.
Paid access is tied to the Google account that makes the purchase. One purchase provides access for one Google account, and can be used for as many sheets as you like.
When you share sheets with others, they can see the data returned by your API requests and triggers. However, the add-on will run under their own Google account, meaning they won’t be able to create their own triggers or access other paid features unless they also have paid access.
You can cancel your subscription at any time, just send a note through the API Connector Contact Form. Your subscription will be canceled immediately, no questions asked.
When you cancel your subscription, you won’t get billed again, and your subscription will remain active to the end of your billing period.
