Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| Replace Images | Web / API | HTTP Request | POST |
| Error Missing Fields | Web / API | Respond To Webhook | See node parameters |
| Respond to Webhook | Web / API | Respond To Webhook | See node parameters |
| Webhook | Trigger | Webhook | See node parameters |
| Retrieve matching Images ObjectIds | Code | Code | See node parameters |
| Retrieve All Slide Elements | Web / API | HTTP Request | See node parameters |
| Check if all params are provided | Routing | If | See node parameters |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.

Dynamically Replace Images in Google Slides
Dynamically Replace Images in Google Slides
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.
Step 1: Set Up a Key Identifier in Google Slides
Add a unique key identifier to the images you want to replace.
- Click on the image.
- Go to Format Options and then Alt Text.
- Enter your unique identifier, like
client_logoorbackground.
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/spreadsheets/d/REPLACE_WITH_DOCUMENT_ID/edit#slide=id.p)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!
Happy automating! The n8Ninja
