Contact form 7 to api + Basic auth

I am using a WordPress version of 5.0.3, I installed the Contact form 7 to api + Basic auth plugin for the purpose of passing the JSON data to our API.

I referred the API URL and passed the JSON data in the Contact form 7 to api + Basic auth plugin. Once contact form has been submitted, we cannot pass the form data to the API.

Please suggest your ideas, how to call our API and pass the form data.

Also, Please share the suggestion, how can we use the Basic Auth in the API Integration.
