WP Caldera Form Processors conneted to custom API

We need to create processors for Caldera forms for the operations with certificates using API: 1. Processor to check the balance of points by the certificate number using API. 2. Processor to use points for the certificate number using API. 3. Processor to change the status of the unpaid certificate by the certificate number using API. All the forms with fields are created on test wp-project on the test server. We need only to create the processors. Full description of processors: 1. Get certificare info. Form must get from API information about certificate by certificate number and put it on the form fields. 2. Change certificate payment status. Form must send API request to change certificate payment status by certificate number. 3. Spend certificate amount. Form must send API request to spend some amount from certificate balance.
