Field	Type	Description
Authorization	Bearer ${token}	Use Authorization: Bearer ${token} for authentication. Get the key from the API Keys page as token.
Content-Type	application/json	Data type, set to application/json.

Request Body

Field	Type	Required	Description
text	string	Yes	Either text or files must be entered. The user's text message, the length of the text content cannot exceed the token length limit set by the Bot configuration.
files	JSON Array	No	text and files must have at least one input. Files are used to submit images, audio, and document-type data to the Bot. The Bot supports two file recognition schemes: "System File Recognition" and "LLM File Recognition." Different recognition schemes support different file types. Network paths for file submission are supported, with a maximum of 9 files uploaded. Documents ≤20MB, images ≤10MB, audio ≤5MB. LLM File Recognition The supported file types depend on the capabilities of each LLM. If it's a flowbot, the intersection of all LLM-supported file types is taken. System File Recognition The GPTBots system recognizes uploaded files and converts them to text. Document types: .pdf, .txt, .docx, .csv, .xlsx, .html, .c, .cpp, .java, .json, .md, .php, .pptx, .py, .rb, .tex, .css, .js, .ts, .xml Image types: .jpg, .jpeg, .png, .gif, .webp Audio types: .mp3, .wav, .acc File Submission Specifications base64_content, string, file stream (choose one with file URL link) url, string, file URL link (choose one with file stream) name, string, file name width, int, image width (required for image types) height, int, image height (required for image types)
conversation_id	string	Yes	Conversation ID, pass in to continue previous conversation.
response_mode	string	Yes	blocking: Blocking, wait for completion before returning result. (Long requests may be interrupted) streaming: Streaming response, based on SSE (Server-Sent Events).
short_term_memory	boolean	No	Does this message send carry short-term memory within the conversation as context? If not filled out, follow the memory settings of the Bot.
long_term_memory	boolean	No	Does this message send carry long-term memory within the conversation as context? If not filled out, follow the memory settings of the Bot.
knowledge	object	No	The message sent this time, in the knowledge base retrieval, only retrieves the knowledge data defined in this parameter as the retrieval scope.
- data_ids	array	No	The knowledge ID for knowledge base retrieval. If this parameter is not submitted, it is considered as no restriction on the retrieval range, that is, querying all knowledge documents of the entire Bot. If this parameter is submitted, and the array is empty, such as `[]`, it is considered as not retrieving any knowledge documents. If there are `data_ids` in the array, the retrieval is performed based on these `data_ids`.
