+18. ### Simple Flow Builder
+
+#### Core Features
+
+##### Flow Creation:
+
+* Users can create a flow with a name and description.
+* Each flow consists of one or more tasks (each task should have a default input on creation).
+* Tasks are executed sequentially (non-branching).
+
+##### Task Actions:
+
+* Each task performs a specific action with a single input.
+* Supported action types:
+	+ Send Test Mail: Sends an email to the provided address.
+		- Input: Email address (e.g., `test@example.com`).
+	+ HTTP GET Request: Performs a GET request to the provided URL.
+		- Input: URL (e.g., `https://api.example.com/data`).
+	+ MySQL Select: Executes a SELECT query on a specified table and ID.
+		- Input: Table name and ID (e.g., `users|123` [select from users where id = 123]).
+	+ Drive Upload: Writes text to a file and uploads it to Google Drive.
+		- Input: Text content (e.g., `Hello, World!`).
+        - Hint: Create a google drive service account, enable drive api, generate credentials and utilize google sdk or api to upload.
+
+##### Triggers:
+
+* Webhook Trigger:
+	+ A GET request with the action input in the query parameter called `payload`.
+	+ Example: `localhost:3001?payload=test@example.com` (triggers the "Send Test Mail" action).
+* Click Trigger:
+	+ On clicking a button, show a popup to receive the action input.
+	+ Example: Click a button, enter `test@example.com`, and trigger the "Send Test Mail" action.
+
+##### Execution:
+
+* When a flow is triggered, execute all tasks in sequence.
+* Log the results of each task execution in a database table (`flow_logs`).
