Requesting Resource for IVR Development

[nsssayom]

I want to use asterisk to create a REST API interface that will generate phone calls according to a delivered JSON like the following-

{
  "recipient": "+88001122334455",
  "callId": "ABCD1234",
  "meta": {
    "superImportantMeta": "Very Important meta Info",
    "anotherSuperCriticalMetaInfo": "hello meta info"
  },
  "callbackOnFailed": "https://webhook.ht/api/v2/call-jay-nai",
  "callbackOnFailedMethod": "PUT",
  "callbackOnFailedPayload": {
    "customMeta": "Loren Ipsum",
    "anotherCustomMeta": "Neque ornare"
  },
  "callFlow": [
    {
      "text": "This is the root of the call. Do you want to proceed? If you agree, press 1, If you decline, press 2",
      "options": [
        {
          "onPress": "1",
          "callback": "https://webhook.ht/api/v2/ja-iccha-tai",
          "callbackMethod": "POST",
          "callbackPayload": {
            "callID": "ABCD1234"
          },
          "callFlow": {
            "text": "This is a level 2 call. Press * to accept and # to decline",
            "options": [
              {
                "onPress": "*",
                "callback": "https://webhook.ht/api/v2/ja-iccha-tai",
                "callbackMethod": "POST",
                "callbackPayload": {
                  "callID": "ABCD1234"
                }
              },
              {
                "onPress": "#",
                "callback": "https://webhook.ht/api/v2/ja-iccha-tai",
                "callbackMethod": "POST",
                "callbackPayload": {
                  "callID": "ABCD1234"
                }
              }
            ]
          }
        }
      ]
    }
  ]
}

I have been looking for resources to get myself started on the project with asterisk. But, unfortunately, I can not find enough resources for a clean start. All the asterisk terminologies seem very new to me and a clear step-by-step guide would be very helpful.

How will you call the api?
