Export the generated API key as an environment variable.
_10export LANGFLOW_API_KEY="sk-..."
The examples in this guide use environment variables for these values.
+Base
+Use the base Langflow API to run your flow and retrieve configuration information.
+Get all components
+This operation returns a dictionary of all Langflow components.

_10curl -X GET \_10 "$LANGFLOW_URL/api/v1/all" \_10 -H "accept: application/json"
_10A dictionary of all Langflow components.
Run flow
+Execute a specified flow by ID or name.
+The flow is executed as a batch, but LLM responses can be streamed.
+For more configuration options when building your flow, use the /build endpoint instead.

This result is abbreviated, but illustrates where the end event completes the LLM's token streaming response.
Webhook run flow
+The webhook endpoint triggers flow execution with an HTTP POST request.
+When a Webhook component is added to the workspace, a new Webhook cURL tab becomes available in the API pane that contains an HTTP POST request for triggering the webhook component, similar to the call in this example.
+To test the Webhook component in your flow, see the Webhook component.

Build
-Use the /build endpoint to build vertices and flows.
Use the /build endpoint to build vertices and flows, and execute those flows with streaming event responses.
The /build endpoint offers additional configuration for running flows.
For a simpler execution of your flows, use the /run endpoint instead.
Build flow
This example builds a flow with a given flow_id.
LLM chat responses are streamed back as token events until the end event closes the connection.

This output is abbreviated, but the order of events illustrates how Langflow runs components.
- Langflow first sorts the vertices by dependencies (edges) in the
vertices_sortedevent:
_10ChatInput-8VNJS → Prompt-CDhMB → OpenAIModel-mXCyV → ChatOutput-Up0tW
_10ChatInput → Prompt → OpenAIModel → ChatOutput
- The Chat Input component receives user input in the
add_messageevent. - The Prompt component is built and executed with the received input in the
end_vertexevent.
@@ -70,119 +104,20 @@ The - The clean
endevent tells you the flow executed with no errors. If your flow executes with errors, theerrorevent handler prints the errors to the playground.
token event represents individual pieces of text as they'r
You can also pass values for start_component_id and stop_component_id in the body of the command to control where the flow run will start and stop.
+
Configure the build endpoint
+The /build endpoint accepts values for start_component_id and stop_component_id to control where the flow run will start and stop.
+Setting stop_component_id for a component triggers the same behavior as clicking the Play button on that component, where all dependent components leading up to that component are also run.
For example, to stop flow execution at the Open AI model component, run the following command:
_10curl -X 'POST' \_10 "$LANGFLOW_URL/api/v1/build/$FLOW_ID/flow" \_10 -H 'accept: application/json' \_10 -H 'Content-Type: application/json' \_10 -H "x-api-key: $LANGFLOW_API_KEY" \_10 -d '{"stop_component_id": "OpenAIModel-Uksag"}'
