What is the process to develop a Gmail add-on?

I’m interested in building a custom add-on for Gmail, but I’m having difficulty finding the necessary API or documentation to guide me through the process. I would like to know if there is an alternative method or updated resource that explains how to integrate such functionality with Gmail. Any detailed steps, insights, or best practices that can help me create a seamless add-on would be highly appreciated. Your guidance on tools or libraries that might support this integration is also welcome.

During my attempt at creating a custom Gmail add-on, I noticed that even though the official guidelines can sometimes be confusing and seem outdated, approaching the task incrementally made a big difference. I began by focusing on setting up a basic integration using Apps Script and then gradually introduced more complex features as I became comfortable with the interface. Experimenting with the Google Workspace sandbox also helped me understand the structure better. By keeping my work modular, troubleshooting became simpler, resulting in an overall smoother development process.

In my experience, building a Gmail add-on is more accessible when using Google Apps Script within the reusable Google Workspace add-ons framework. Although official documentation might appear scattered and at times outdated, exploring the sample projects and sandbox environments has proven invaluable. I found that carefully testing each component and referring to community discussions on relevant forums provided clarifications that are not always evident in the official guides. It is advisable to break the add-on into modular parts to debug more effectively and ensure smooth integration with Gmail.

hey, try using google apps script for gmail add-ons. docs r a bit dated so codelabs and sample code helped me out. might need some trial & error but its fun exploring it. good luck!

hey, i struggled with it too! i found using recent codelabs and experimenting with tiny sample scripts really helped me get a handle on this messy docs. sometimes a slow, step-by-step approach clears the fog. good luck exploring!

Working on a Gmail add-on was initially intimidating due to fragmented documentation, so I adopted a trial-and-error approach using Google Apps Script. I started by building minimal features, which helped me uncover the nuances of the Gmail API integration. I relied on both official resources and community-shared snippets to fill in gaps in the guides. Breaking the task into smaller segments enabled me to test each function independently, leading to a more robust final product. This iterative process made it easier to troubleshoot and adapt as I learned more about the underlying system.
