Integrate NASA with 500+ apps and services

This is a workflow that sends daily astronomy picture of the day using the NASA node to a channel on Telegram. Cron node: The Cron node triggers the workflow daily at 8 PM. You can update the time in the Cron node to trigger the workflow at your desired time. NASA node: After the Cron node triggers the workflow, the NASA node fetches the Astronomy Picture of the Day from the NASA API. You can also get the binary file of the image. Toggle Download Image to true to get the file. Telegram node: The Telegram node sends the image to a Telegram channel. If you want to share the image on another platform, you can replace the Telegram node with the node of that platform. For example, if you want to post the image on a channel on Slack, replace the Telegram node with the Slack node. You can learn to build this workflow on the documentation page of the NASA node.

How it works This workflow shows how to set credentials dynamically using expressions. It accepts an API key via a form, then uses it in the NASA node to authenticate a request. Setup steps First, set up your NASA credential: Create a new NASA credential. Hover over API Key. Toggle Expression on. In the API Key field, enter {{ $json["Enter your NASA API key"] }}. Then, test the workflow: Get an API key from NASA Select Test workflow Enter your key using the form. The workflow runs and sends you to the NASA picture of the day.
