Changes to drive.google.com/uc URLs which break embedding images/files from Google Drive in your websites and AppSheet apps

Google Drive broke the ability to embed images with the /uc path. Here’s how to embed images from Google Drive in your website.

Previously Google Workspace developers could use a /uc path for embedding images and other files hosted in Google Drive. For example, images could be embedded in websites and emails using markup like:

<img src="https://drive.google.com/uc?export=view&id=1234567890abcdef" />

To my knowledge this was never an officially documented endpoint, but widely known about and shared within the community. Back in October 2023 Google announced Upcoming changes to third-party cookie requirements in Google Drive, which has started rolling out from the beginning of 2024.

The impact of this change is it breaks /uc embeds and these have started returning 403 errors. There is no reference to the /uc endpoint in the original announcement, which is why I think many people are only just finding out about the impact now. Google’s official guidance is to move to <iframe> with Google Drive publish and preview links. This post from Justin Poehnelt discusses the options and limitations for images.

There has also just been another announcement in the AppSheet community that Drive download URLs for embeddable content to be updated by May 1st, 2024. This is an extended window for AppSheet users and where possible Google will be emailing affected app owners where /uc urls have been detected. This announcement includes a link to a help page with tips for finding /uc occurrences in your AppSheet apps.

How to automatically rename files in Google Drive with Apps Script and the Vertex AI Gemini API

Quickly rename files in Google Drive with Apps Script and Google Gemini AI. The script will automatically rename the files with a descriptive name based on the image content.

Amit Agarwal is celebrating 20 years of ‘Digital Inspiration’, one of my go to resources for Google Workspace tech tips, tutorials and how-to guides. This recent post from Amit is a great example of the types of solutions he regularly shares. This time Amit is looking at how the Generative AI capabilities of the Gemini API can be used to help rename images in Google Drive. To achieve this there Amit shares handy Apps Script snippets for finding images in a Google Drive folder, grabbing the thumbnail images as Base64 encoded strings before calling the Gemini Pro Vision API to get suggested filenames with the prompt:

Analyze the image content and propose a concise, descriptive filename in 5-15 words without providing any explanation or additional text. Use spaces instead of underscores.

For this solution an API key for Gemini Pro Vision is generated in Google AI Studio (formerly MakerSuite). There are still geographic restrictions on access to Google AI Studio, but given Apps Script runs on Google servers once you have a API key you can continue to use it without having to proxy a location.

Adding image capabilities to the GeminiApp Apps Script library has been on my TODO. Now I’ve got an example to play with it should be easier to do .. thank you Amit Agarwal.

Semantic poetry with Google Apps Script – Using Semantic Retrievers and Attributed Question and Answer (AQA) in Google Workspace

Imagine this: you recall a document about an intriguing subject but can’t pin down a specific term. It’s a common scenario where traditional search methods in Gmail or Google Docs often fall short, relying heavily on exact terms. Enter the realm of ‘semantic’ search, powered by advanced language models. ‘Semantic’ isn’t just a fancy word; it’s about understanding the meaning and context behind your words. Instead of a frustrating keyword hunt, these models interpret your descriptions, no matter how vague, to find that needle in the digital haystack.

“Code is Poetry” is the tagline popularised by the open-source blogging platform WordPress. In this post from Riël Notermans at Zzapps.nl ‘code is FOR poetry’. It’s well worth spending the time unpick what is happening in this tutorial. To help understand the implications I would also recommend watching this short video on the Google Workspace Developers channel where Riël explains how the technique can be used for other applications like knowledge bases.

Even if you are not interested in generating poetry it’s an opportunity to see how the Vertex AI Generative Language API can be used in Google Workspace, in this instance to generate text for a Google Doc using a corpus of data from your Google Drive. Follow the source link for the code and setup instructions.

Creating a usage dashboard for your Google Workspace Marketplace Add-on with LookerStudio, BigQuery and Logging Sinks

Flubaroo Add-on Dashboard

At the moment, Add-ons in Google Workspace offer only basic usage analytics via the Workspace Marketplace SDK. These include install data broken out by domains and seats (for Add-ons installed by Workspace admins), and individual end-user installs. This is useful information, but doesn’t tell you much about who is actively using your Add-on, nor give you the ability to breakdown that usage by different dimensions.

The code and instructions in this repo will help you gather and visualize Add-on usage data, such as active usage of your Add-on broken out by user characteristics. It also shows you how to log specific events that correspond to use you want to track (i.e. new installs, uses of particular features, etc).

Here’s a useful solution for Google Workspace Add-on developers who would like more actionable insight into their Google Workspace Add-on usage. This isn’t an official Google solution but comes from the creator of the very popular Flubaroo add-on, Dave Abouav.

The solution includes a Google Apps Script helper snippet which enables your add-on to ‘call home’, or in this case into Cloud Logging, with basic user metrics as well as other events you would like to log. The project also details how you can route usage logs from Cloud Logging into BigQuery by creating a ‘sink’ in Google Cloud Log Router.

The final step is creating a LookerStudio dashboard to visualise the BigQuery data. As noted by Dave there is a cost to using BigQuery for long term storage and querying, which should be kept in mind. More details in the source link below.

H/T to Chanel Greco for highlighting this solution.

‘Editing’ Microsoft files (Word, Excel, and PowerPoint) with Google Apps Script

In this report, I would like to introduce the sample scripts for using Microsoft Docs files with Document service, Spreadsheet service, and Slides Service of Google Apps Script.

Users have had the ability to edit MS Word, Excel and PowerPoint files directly in Google Drive for a number of years, Google making this the default behaviour in 2020. There aren’t currently any APIs or Apps Script services that enable you to edit these particular document types. This however hasn’t stopped Kanshi Tanaike for developing and sharing the MicrosoftDocsApp library which makes it possible to edit MS Word, Excel and PowerPoint files using the same methods as you would for Google Docs, Sheets and Slides.

The library is able to do this by converting the Microsoft files into the Google equivalent, before using the MS export options in Google Drive to replace the original files. This does create some limitations highlighted in the post. In particular, the original documents are overwritten and not directly edited which means any incompatible feature as part of the Microsoft to Google conversion will be lost. Regardless of these it’s a clever approach and might be useful for users who have to keep feet in both the Google and Microsoft worlds.

Google Apps Script Service Account impersonation without downloading private service account keys 

Avoid downloading private service account keys by using impersonation in Apps Script to obtain access tokens.

For Google Workspace Admins you can gain super powers (and super responsibility) using Google Cloud project service accounts. A common scenario is using service accounts with domain-wide delegation to make API calls impersonating Google Workspace users. With this you can do things like set a user’s Gmail settings including signatures, authenticate as a user in Google Chat and much more.

A quick way to use a service account is to download a JSON key. The challenge then given the potential capabilities of service accounts is securely storing the JSON key. A alternative approach, which is explained in this post by Justin Poehnelt, is using Apps Script to create and fetch a short-lived credential for your service account.

Short-lived credentials are highly recommended for applications requiring robust security and precise access control for service accounts, reducing the attack surface and the risks with accidentally exposing static secrets.

You can find out more include code snippets/setup in Justin’s post which also links to the support documentation.

Create a Google Chat Bot on your own data with Vertex AI Search and Google Apps Script

Create a Chatbot answering user questions based on your documents. RAG implementation with multiturn using Vertex AI Search and Apps Script

More GenAI, this time from Stéphane Giron looking at how Apps Script can be used to provide the glue for a Google Chat app powered by Vertex AI Search. In this example you can see how unstructured data like PDF documents can easily be uploaded to a Cloud Storage folder, which then become the knowledge base for the Chat app. The post includes a Google Apps Script snippet for sending messages to the Vertex AI Search API as well as instructions on how to create the chatbot, including how to import data into Vertex AI Search and how to integrate the chatbot into Google Chat.

The post is a great summary of what is possible when combining Google Chat and Vertex AI Search. If you are interested in finding out more about what is possible using Vertex AI Search with follow-ups Google provide a comprehensive guide.
