List Conversation Messages

Available for: Chatflow

Returns a conversation’s history in scroll-loading form. Without first_id, the newest limit messages come back in chronological order; with first_id, the messages before it.

Standard API equivalent: List Conversation Messages. Differences:

user is required.
These response fields never vary:
- feedback is always null.
- retriever_resources is always empty.
- agent_thoughts is always empty.
- parent_message_id is always the all-zero UUID.
Error codes differ.

Authorizations

Authorization

string

header

required

Every request authenticates with an API key: Authorization: Bearer {API_KEY}. App endpoints take an app API key; knowledge endpoints take a knowledge base API key (Get Started).

Keep keys server-side; never embed them in client code. Requests with a missing or invalid key fail with HTTP 401 (unauthorized).

Query Parameters

user

string

required

End-user identifier, defined by your app and unique within it. Conversations belong to the app, the environment, and this user together; later reads and changes must send the same value. See End User Identity.

Required string length: 1 - 255

conversation_id

string<uuid>

required

ID of the conversation to read. Get conversation IDs from List Conversations.

first_id

string<uuid>

Pagination cursor: the id of the first message on the current page. Pass it to fetch the previous (older) page; omit to fetch the latest messages.

limit

integer

default:20

Number of chat history messages to return per request.

Required range: 1 <= x <= 100

One page of the conversation's messages, oldest first.
