You need to set default value in config.xml.

You can follow here LINK

• user3713377: Please note the default tags at the bottom: <default> <connector_api_credentials> <api> <enabled>No</enabled> </api> </connector_api_credentials> </default>
• Chirag Rajput: Yes i see in your code. its in system.xml , but you need to put that code in config.xml and have a look at [Reference] (stackoverflow.com/questions/38528551/…)
