About this template

This app is a fast API endpoint that will automatically post a tweet provided via the API to a company's Twitter account. Can be used in your product to promote certain things happening, for example a product community member does something and you tweet automatically about it. Ideal for automatic tweets posting for company updates. Steps: 1. Sign up for a developer account on https://developer.twitter.com/ (you have to log in with the company's Twitter handle) 2. There's a free option (even though they are pushing the $100 per month basic option you don't need that to get started and for small volumes) 3. Navigate to projects and apps 4. From the consumer keys section copy the API key and Secret into Env Secrets tab in Lazy (make sure variable names are correct) 5. Generate an Access Token and Secret and copy them into Env Secrets tab in Lazy (make sure variable names are correct) THESE MUST HAVE READ AND WRITE ACCESS OTHERWISE IT WON'T WORK 6. Generate a bearer token and add to env secrets 7. Use the Fast API docs page to test app and try to post using the API endpoint or make a sample request directly. 8. Check your Twitter for the post appearing and voila!

Introduction to the Fast API Endpoint for Automatic Tweet Posting Template

Welcome to the Fast API Endpoint for Automatic Tweet Posting template! This template allows you to create an application that can automatically post tweets to a Twitter account. It's perfect for promoting events, sharing updates, or engaging with your audience without manual intervention. In this article, we'll guide you through the process of setting up and using this template on the Lazy platform.

Getting Started

To begin using this template, click on "Start with this Template" on the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy or paste any code manually.

Initial Setup: Adding Environment Secrets

Before you can start using the application, you'll need to set up some environment secrets. These are necessary for the app to authenticate with Twitter and post messages on your behalf. Here's how to obtain and set up these secrets:

  1. Sign up for a developer account at Twitter Developer Platform using your company's Twitter handle.
  2. Choose the free option during the sign-up process.
  3. Navigate to the "Projects and Apps" section and create a new app.
  4. From the "Keys and Tokens" section of your app, copy the API Key and API Secret Key.
  5. Generate an Access Token and Access Token Secret, ensuring they have both read and write access.
  6. Generate a Bearer Token for your app.
  7. Go to the Environment Secrets tab in the Lazy Builder and add the following secrets with the corresponding values you obtained:
    • TWITTER_BEARER_TOKEN
    • TWITTER_ACCESS_TOKEN
    • TWITTER_ACCESS_TOKEN_SECRET
    • TWITTER_API_KEY
    • TWITTER_API_SECRET_KEY

Test: Deploying the App

Once you have set up the environment secrets, you can deploy the app by pressing the "Test" button. This will launch the Lazy CLI and begin the deployment process. If the app requires any user input, you will be prompted to provide it through the CLI.

Using the App

After deployment, Lazy will provide you with a dedicated server link to interact with your new API. You can use this link to send POST requests to the "/post_message" endpoint with a JSON payload containing the message text you want to tweet.

Here's a sample request you might send to the API:


POST /post_message HTTP/1.1<br>
Host: [Your Server Link]<br>
Content-Type: application/json<br>
<br>
{
  "text": "Hello, world! This is an automated tweet from Lazy."
}

And a sample response indicating success might look like this:


HTTP/1.1 200 OK<br>
Content-Type: application/json<br>
<br>
{
  "message": "Tweet successfully posted!"
}

Integrating the App

If you want to integrate this app into your product or service, you can use the server link provided by Lazy to set up HTTP POST requests from your application. Ensure that the requests are authenticated and formatted correctly according to the Twitter API and FastAPI documentation.

Remember, this app is designed to work within the Lazy platform, so all the heavy lifting of deployment and environment management is handled for you. Just follow the steps above to get started with automatic tweet posting!

Search Email with GMail API

This is a FastAPI-based application that uses Google’s Gmail API to fetch and display emails based on user-defined search queries. It provides a /search_emails endpoint for email searches and a /oauth2callback endpoint for OAuth2 callbacks. The app requires the environment variables CLIENT_ID, CLIENT_SECRET, and REDIRECT_URI for OAuth2 authentication. These credentials pertain to your Google API and must be set correctly for the application to function as expected.
