ChatGPT (OpenAI)

ChatGPT Integration

ChatGPT supports external tools through the Actions/Plugins system. For detailed configuration instructions, visit the official documentation.

To integrate Timbr:

Option 1: Custom GPT with Actions​

  1. Create a Custom GPT at chat.openai.com
  2. Go to Configure → Actions → Create new action
  3. Use the JSON link for the swagger.json OpenAPI schema from the link in the Timbr Swagger endpoint in your environment
  4. Configure Authentication:
    • Authentication Type: API Key
    • Auth Type: Custom Header
    • Header Name: x-api-key
    • API Key: Your Timbr API key (tk_...)

Option 2: Direct API Integration​

Use ChatGPT's function calling with the Timbr REST API directly (non-MCP) using a Timbr agent:

POST https://<your-timbr-server>/timbr/openapi/execute/prompt
Headers:
  x-api-key: tk_your_api_key
  agent: agent_name
  Content-Type: application/json
Body:
  {"prompt": "Show all customers"}

Use ChatGPT's function calling with the Timbr REST API directly (non-MCP) using an ontology:

POST https://<your-timbr-server>/timbr/openapi/execute/prompt
Headers:
  x-api-key: tk_your_api_key
  ontology: my_ontology
  Content-Type: application/json
Body:
  {"prompt": "Show all customers"}
