+## Using ChatGPT within Glific using the OpenAI APIs
+
+_**Leverage the capabilities of GPT models developed by OpenAI by using OpenAI APIs.**_
+
+## Pre-requisites
+1. Create an account in OpenAI platform [platform](https://openai.com/product)
+2. Create new API keys
+3. Make sure there is enough credit in OpenAI account to allow usage.
+4. Pricing for API calls is as per OpenAI platform [pricing](https://openai.com/pricing)
+
+
+
+_Above is a representative image from the OpenAI platform account_
+
+## How it will work
+
+1. Question is asked by the user after the flow is initiated
+2. OpenAI API call is made using webhooks within the flow
+3. Model being called to generate responses is `gpt-3.5-turbo-16k`
+4. The response to the question is then sent to the user
+
+## Steps to follow to set up OpenAI API in Glific platform
+1. Go to `Settings`, find `OpenAI (ChatGPT) (Beta)`
+2. Click on `is active` and paste the OpenAI API key from your OpenAI platform account
+
+
+
+## Using the webhook for OpenAI API call in a Glific flow
+
+
+
+_Representative image to explain the steps in OpenAI API calls in a simple flow_
+
+[Sample flow](https://drive.google.com/file/d/1jl0NWn73YlK1qMRedaPnGCQwDKHfG_7j/view?usp=drive_link)
+
+
+1. Get the user question
+2. In `call a webhook` node, select `function` and paste function name as `parse_via_chat_gpt`
+
+
+
+3. Share the following function body
+ ` {
+ "contact": "@contact",
+ "results": "@results",
+ "question_text": "@results.question"
+ }`
+
+here `question_text` is the parameter name corresponding to user question.
+
+
+
+4. The response from GPT is shown as `@results.webhookresultname.parsed_msg`, in the given example `gpt_response` is the webhook result name.
+
+
+## Limitations
+1. At present, this is simple question answer with the GPT model `gpt-3.5-turbo-16k`
+2. Selection of GPT model is not yet customizable from org Glific instances
+3. Additional system prompt is not yet customizable from org Glific instances
+4. Parameters like temperature, top P etc are not yet customizable from org Glific instances
+
+_Reach out to the Glific team to flag any further customizations within this functionality_
