To add flows and components at project creation, retrieve the components_list and flows_list values from the /all and /flows/read endpoints and add them to the request body.

Adding a flow to a project moves the flow from its previous location. The flow isn't copied.

bash

curl -X POST \
  "$LANGFLOW_URL/api/v1/projects/" \
  -H "accept: application/json" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $LANGFLOW_API_KEY" \
  -d '{
  "name": "new_project_name",
  "description": "string",
  "components_list": [
    "3fa85f64-5717-4562-b3fc-2c963f66afa6"
  ],
  "flows_list": [
    "3fa85f64-5717-4562-b3fc-2c963f66afa6"
  ]
}'

To find the UUID of your project, call the read projects endpoint.

bash

curl -X GET \
  "$LANGFLOW_URL/api/v1/projects/$PROJECT_ID" \
  -H "accept: application/json" \
  -H "x-api-key: $LANGFLOW_API_KEY"

    "parent_id": null
  }
]

</details>

Update project

Update the information of a specific project with a PATCH request.

Each PATCH request updates the project with the values you send. Only the fields you include in your request are updated. If you send the same values multiple times, the update is still processed, even if the values are unchanged.

bash

curl -X PATCH \
  "$LANGFLOW_URL/api/v1/projects/b408ddb9-6266-4431-9be8-e04a62758331" \
  -H "accept: application/json" \

  -d '{
  "name": "string",
  "description": "string",
  "parent_id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
  "components": [
