+**Learn how to integrate Apify with Langflow, in order to run complex AI agent workflows.**
+

+
+## What is Langflow?
+
+[Langflow](https://langflow.org/) is a visual low-code tool for developers that makes it easier to build powerful AI agents and workflows that can use any API, model, or database.
+
+> For more information on Langflow, visit its [documentation](https://docs.langflow.org/).
+
+## How to use Apify with Langflow
+
+To show how to use the platform, we are going to create an example AI agent workflow that will search the web for social media profiles of a given company and then extract data from the profiles. We will use the [Google Search Results Scraper](https://apify.com/apify/google-search-scraper) Actor to search the web for social media profiles of a given company. Then we will use the [TikTok Data Extractor](https://apify.com/clockworks/free-tiktok-scraper) Actor to extract data from the TikTok profiles.
+
+> Langflow can either be installed locally or used in the cloud. The cloud version is available on the [Langflow](http://langflow.org/) website. If you are using the cloud version, you can skip the installation step.
+
+### Installation
+
+First, we need to install the Langflow platform using [uv](https://docs.astral.sh/uv/):
+```bash
+uv pip install langflow
+```
+
+After the successful installation of Langflow, we can start the platform:
+```bash
+uv run langflow run
+```
+Other installation methods can be found in the [Langflow documentation](https://docs.langflow.org/get-started-installation).
+
+When the platform is started, open the [Langflow UI](http://127.0.0.1:7860) in your browser.
+
+### Building your flow
+
+In the Langflow welcome screen, click the **New Flow** button:
+![Langflow welcome screen - New Flow](../images/langflow/new_flow.png)
+
+In the **New Flow** screen, click **Blank Flow**:
+![New Flow screen - Blank Flow](../images/langflow/new_blank_flow.png)
+
+From the bundle menu on the left side, add two **Apify Actors** components:
+![Flow - Add Apify Actors](../images/langflow/bundles_apify.png)
+
+Input your API token (learn how to get it [here](https://docs.apify.com/platform/integrations/api))
+and set the Actor ID of the first component to `apify/google-search-scraper` and the second one to `clockworks/free-tiktok-scraper`:
+![Flow - Actors configuration](../images/langflow/apify_actors_configuration.png)
+
+Now add the *Agent* component from the menu and set your OpenAI API key (get it [here](https://platform.openai.com/account/api-keys)):
+> For better results, switch the model to `gpt-4o` instead of `gpt-4o-mini` in the Agent configuration
+
+![Flow - Add Agent](../images/langflow/add_agent.png)
+
+Then connect the Apify Actor components **Tool** output to the Agent component **Tools** input:
+![Flow - Agent configure](../images/langflow/agent_configure.png)
+
+Now add **Chat Input** and **Chat Output** components from the menu and connect them to the Agent component **Input** and **Response**:
+![Flow - Add Chat components](../images/langflow/add_chat.png)
+
+The flow should look like this:
+![Flow - Final](../images/langflow/flow.png)
+
+Click the **Playground** button in the top right corner and chat with the Agent to test the flow:
+![Flow - Playground](../images/langflow/playground.png)
+
+Here is an example Agent output for the following query:
+```
+find tiktok profile of company alza.cz using google search and then show me the profile bio and their latest video
+```
