GOG support for uninstalled too?

[BanCrash]

Hello, by chance I found an unofficial GOG api documentation that shows how to get all the games an account have:

https://gogapidocs.readthedocs.io/en/latest/

In concrete, the part I think could be useful is:

https://gogapidocs.readthedocs.io/en/latest/account.html#games-movies

I don't know if there is a way to work with this, but just in case I let this here for if you want to check it out!

EDIT: A topic on GOG official forum talking about this: https://www.gog.com/forum/general/unofficial_gog_api_documentation/page1

EDIT 2: After a little research I see that you have first to log in in your web browser, and then with the link you get directly from GOG you can access locally to your account and make that call for your games. There is also an implementation of this in github (at least, I think it is) https://github.com/Yepoleb/pygogapi

TL;DR: Looks intriguing, but I have some questions and concerns about using the API and existing wrappers. Don't expect to see it implemented in Lauhdutin any time soon.

Neat. The 1.2.x updates to GOG Galaxy changed some of the local files and now there is a local database with information on all GOG games (prior versions only populated a similar local database with info on games viewed by the user via the Galaxy client i.e. only games that probably already were installed), but it does not include a list of owned games for accounts that have logged in so this is along the lines of what I've been looking for.

I still haven't found an API/protocol for interacting with the Galaxy client itself like one can with the Steam and Battle.net clients, but at least Lauhdutin could for example start the Galaxy client. It would be nice to have it be able to also either open up the page for the game or even bring up the GUI for starting the installation of the game.

However, I do have some concerns:

• Handling account names and passwords is a can of worms all on its own.
• How trustworthy is any unofficial, 3rd party code that one might be giving passwords to?
• GOG's API doesn't appear to be ready for public use. There is no official documentation on details like rate limits. Where did the client ID and secret used for the authentication come from? Are there any risks (e.g. account closure if it is seen as misuse or breach of TOS) involved with using the API in its current state?

EDIT: Some of these questions and concerns may have answers already, but it'll take a while to read and process all of the material out there.

Hello, I understand all your concerns. However maybe I found a better way:

ProgramData\GOG.com\Galaxy\storage

In this folder there is a file named ownership.db that have a sql database that shows all games you have been installed every time (in the ProductOwnership table), even if now it is not installed. The important thing about this is, even if you only pulse the install button on GOG galaxy, and then pulse cancel button, that game will appear in this database:

In this screen you can see that there is a charging process, in that charging process I think GOG galaxy write the ID to this database. I pulse Cancel after that and surprise:

The main problem is that you have to do this process with all the games you have (pulse install, then cancel), but maybe this is better than the other way?

EDIT:

Other interesting file could be galaxy.db in the same folder, that have a table (Product Details View) with ALL the games GOG have (not only you owned). For example:

With this, I can see easily how game belong to the id I have in the previous file:

I'm aware of those files and their contents (they are some of the files that Lauhdutin's Python backend processes), and I had once upon a time also been hopeful about what could be done with ownership.db. However, as you also noticed the contents only reflect what has been installed (or has been attempted to install). galaxy.db replaced productdetails.db in GOG Galaxy 1.2.x, which is why Lauhdutin 2.7.1 was needed as the latter file had been removed completely when the Galaxy client was updated.

Ah, okay then. Then I hope in the future there is a change on GOG Galaxy on that file or to solve all concerns about that public API.

About this, I found this tool that allows you to download all your GOG games. I know that this tool would have all the concerns of the other tool, just share it for if it is more useful than the other.

The topic on the official GOG forum have 40 pages and it is still alive, so I don't think GOG cares about this. Source

By the way, in the official GOG forum I found too a post that shows how to create a shorcut that launches a GOG game within GOG Galaxy:

Yes you can create shortcuts to use Galaxy:

"GALAXYPATH\GalaxyClient.exe" /command=runGame /gameId=IDNUMBER /path="GAMEPATH"

The uppercase words have to be changed to the specific value. The gameid you can easily see by looking into the game folder and check for files with "goggame-IDNUMBER" in them.

I found that repo as well back when you opened this thread. My previously stated concerns apply to it as well.

Not closing down a discussion/project is not the same as endorsing it. I'd rather wait a while longer to see what happens with the API.

The last part about launching games looks like a really useful piece of information that I wasn't previously aware of. Thanks!

[BanCrash]

Ah, okay!

Sure!

Glad to help!
