How do I connect to external API through power automate for the below scenario

[BleatingOfficer]

Hi, I have an API URL and its key.
If I type a 'question' , it should send an 'answer'

Let me explain with an example:

{
  "prompt": "How to cook fish fry?",
 "max_tokens": 100
}
prompt is the question.
so the response would be...
{
    "choices": [
        {
            "text": "\n\nA: First, preheat a pan or griddle over medium-high heat and add some oil. Next, season your fish fry with some salt, pepper, and other desired spices. Then, carefully place the fish fry in the hot pan or griddle. Cook for 3-5 minutes per side, or until the fish is cooked through. Finally, remove from the heat and enjoy!",
        }
    ],
    "usage": {
        "prompt_tokens": 8,
        "completion_tokens": 81,
        "total_tokens": 89
    }
}
-------------------------------------------
'text' is the answer for that question which i asked,
I have tested it on Post Man, it works but how do i do the same process in power automate?

These steps i tried so far:
-----------------------------

First i created an input called question in power automate (Power apps V2)

and then http trigger, i entered the API URL and header 

{ 

 “Content-Type”: “application/json” 

} 

body: 

{
  "question": "How to cook fish fry?",
 "max_tokens": 100
}
and then i added authentication key
and parse json and got all main content from body
but how does power automate can understand that 'text' is the output that it should display?
then im confused what to do next?

Hi @BleatingOfficer 

In your response below choices is an array. 

{
    "choices": [
        {
            "text": "\n\nA: First, preheat a pan or griddle over medium-high heat and add some oil. Next, season your fish fry with some salt, pepper, and other desired spices. Then, carefully place the fish fry in the hot pan or griddle. Cook for 3-5 minutes per side, or until the fish is cooked through. Finally, remove from the heat and enjoy!",
        }
    ],
    "usage": {
        "prompt_tokens": 8,
        "completion_tokens": 81,
        "total_tokens": 89
    }
}

Once you received the response body add a parse JSON. Then again add another parse json to map the choices json format, add a compose step after and map the text.

Thanks

How do I map the 2 Json choices? Could you elaborate a bit?

Hi @BleatingOfficer 

Parse JSON schema

{

    "type": "object",

    "properties": {

        "choices": {

            "type": "array",

            "items": {

                "type": "object",

                "properties": {

                    "text": {

                        "type": "string"

                    }

                },

                "required": [

                    "text"

                ]

            }

        },

        "usage": {

            "type": "object",

            "properties": {

                "prompt_tokens": {

                    "type": "integer"

                },

                "completion_tokens": {

                    "type": "integer"

                },

                "total_tokens": {

                    "type": "integer"

                }

            }

        }

    }

}

Hi @abm , thanks for replying.

From the above answer, I could understand that we are using response as body and what about this?

{

  "prompt": "How to cook fish fry?",

 "max_tokens": 100

}

The above one is question body. 

The API sends "question (prompt)" as request to this body and receive response from "text" response body.

Should I add both question body and response body?

If yes, what would be the final overflow in power automate from beginning?

Hi @BleatingOfficer 

I am a little lost here. You have given me a schema based on asking you want to extract the text. Could you please give me a full response body?

Thanks

[BleatingOfficer]

Hi @abm 

This is the full response body 

{

    "id": "cmpl-6A9zhMATatSKmbsGwC6XgT8Rotfg1",

    "object": "text_completion",

    "created": 1667879717,

    "model": "text-davinci-002",

    "choices": [

        {

            "text": "\n\nTo write an article and publish it, you will need to find a reputable publication that is willing to accept your article. Once you have found a publication, you will need to follow their guidelines for submitting an article. After your article has been accepted, it will be published in their next issue.",

            "index": 0,

            "logprobs": null,

            "finish_reason": "stop"

        }

    ],

    "usage": {

        "prompt_tokens": 9,

        "completion_tokens": 61,

        "total_tokens": 70

    }

}

---------------------------

And this one is question body:

{

  "prompt": "How to write an article and publish it?",

 "max_tokens": 100

}

---------------

In my power apps, I have a text Input called QUESTION, and whenever I click a submit button called generate answer. 

The question should send to the prompt and receive response (text) from response body.

How do I automate this in power automate flow?
