Dynamically replace images in Google Slides via API

This workflow exposes an API endpoint that lets you dynamically replace an image in Google Slides, perfect for automating deck presentations like updating backgrounds or client logos.

Here's how to get started:

Step 1: Set Up a Key Identifier in Google Slides

Add a unique key identifier to the images you want to replace.

1. Click on the image.
2. Go to Format Options and then Alt Text.
3. Enter your unique identifier, like client_logo or background.

Step 2: Use a POST Request to Update the Image

Send a POST request to the workflow endpoint with the following parameters in the body:

• presentation_id: The ID of your Google Slides presentation.
  You can find it in the URL of your Google presentation: https://docs.google.com/presentation/d/<this-part>/edit)
• image_key: The unique identifier you created.
• image_url: The URL of the new image.

That's it! The specified image in your Google Slides presentation will be replaced with the new one from the provided URL.

This workflow is designed to be flexible, allowing you to use the same identifier across multiple slides and presentations. I hope it streamlines your slide automation process!

Example Curl Request to execute:

curl --location 'https://workflow.url' \
--form 'presentation_id="google-presentation-id"' \
--form 'image_key="background"' \
--form 'image_url="https://picsum.photos/536/354"'

Happy automating!
