Dynamic Parameter Handling in Chat Completion API Integration
Step-by-Step Guide to Dynamic Payloads in Chat Completion API
📌 Step 1: What is a Static Chatbot Payload?
In many chatbot systems, a fixed (static) payload is sent to the API, like:
json
{
"org_id": "/org_id in integration guide",
"chatbot_id": "//chatbot_id in intergration guide",
"user_id": "USER_123", //can be any arbitary value
"variables": { //not compulsory
"name": "abc"
}
}
This is simple, but not flexible. You can’t change the model, prompt, or tools without editing the code.
🔁 Step 2: Why Do We Need a Dynamic Payload?
Real-world apps need to:
Change model (
gpt-4o
,gpt-3.5
, etc.)Update prompts based on user language or logic
Use function calling (tools)
Adjust temperature / token limits
Keep some fields optional
Instead of hardcoding, we use a dynamic payload — a JSON that is constructed at runtime.
🛠️ Step 3: Building a Dynamic Payload Step-by-Step
Here’s a sample dynamic structure you can send:
json
{
"service": "openai",
"configuration": {
"model": "gpt-4o",
"type": "chat",
"prompt": "Act as a bot JSON",
"max_tokens": "default",
"creativity_level": "default"
},
"apikey": "your-api-key"
}
✅ Fields you can customize:
Field | Purpose |
---|---|
| AI model to use (e.g., |
| Bot’s behavior / instructions |
| Functions you want to call |
| Max length of response |
| Controls how strict or creative it is |
🧩 Step 4: Add Tools Dynamically (Function Calling)
If your chatbot needs to use tools, like BMI calculation, you can add them only when needed:
json
"tools": [
{
"type": "function",
"id": "66aa1347f6048aaaf9e5d34b",
"name": "scriSybL2C2K",
"description": "BMI Res",
"required": ["BMI"],
"properties": {
"BMI": {
"type": "string"
}
}
}
]
✅ You only add this section when tool-based replies are needed.
🧠 Step 5: Optional Fields = Clean JSON
You don’t have to send everything all the time.
Examples of optional fields:
system_prompt_version_id
log_probability
repetition_penalty
response_count
Only send them when required. This keeps your payload light and dynamic.
✅ Final Words
Using dynamic payloads gives you power to build smart, scalable, and flexible chatbots. Instead of changing code every time, you just change the JSON payload at runtime.
