Hello DiegoQuibim, When creating a list using "Send a HTTP Request to SharePoint" in Power Automate, ensure you're providing the correct headers and body. Here's an example: **Headers:** - Key: Accept, Value: application/json;odata=verbose - Key: Content-Type, Value: application/json;odata=verbose - Key: Authorization, Value: Bearer YOUR_ACCESS_TOKEN Note: Replace YOUR_ACCESS_TOKEN with the actual access token or ensure your HTTP request is authenticated properly. **Body:** You need to define the properties for your list in the body. Here's an example: ```json { "headers": { "__metadata": { "type": "SP.List" }, "AllowContentTypes": true, "BaseTemplate": 100, "ContentTypesEnabled": true, "Description": "Your list description", "Title": "Your List Name" } } ``` Make sure to customize "Description" and "Title" according to your list requirements. Remember, authentication is crucial for SharePoint requests. Ensure that you have the necessary permissions and the access token is valid. If you encounter specific issues or errors, feel free to share more details, and I can provide further assistance. Have a great day DiegoQuibi!
