At a high level, a typical integration of the Assistants API has the following flow:
Create an Assistant in the API by defining it custom instructions and picking a model. If helpful, enable tools like Code Interpreter, Retrieval, and Function calling.
Create a Thread when a user starts a conversation.
Add Messages to the Thread as the user ask questions.
Run the Assistant on the Thread to trigger responses. This automatically calls the relevant tools.
By clicking the documentation links above, you can view the endpoints you can use for the “Make an API Call” modules. This means you’ll need at least four operations just to setup and initially run a new assistant.
