Getting Error code 675 from message delete while removing all messages from all chat

[martinellimarco]

Hi,

Since Skype is shutting down in May, I'd like to delete all my messages from all chats and close my account.

I wrote a script, which you can find in this gist.

It seemed to work at first, but I’m encountering some issues that I’m not sure how to solve—if they can be solved at all.

The first issue is that, for most messages, when I call delete, I get an exception:
('Error code 675 from message delete', <Response [200]>).

The second issue is that my contacts have told me they’re receiving blank notifications from me. This worries me as I don't want to spam my contacts.

I’m not sure if these two issues are related, that's why I'm grouping them in a single discussion.

I couldn’t find any information about error code 675, so I checked the JSON returned by the Skype API and found:
{'errorCode': 675, 'message': 'Message is deleted'}
which only adds to my confusion.

Except for the most recent messages, it seems they are not actually deleted—although I can delete them manually from the web or desktop versions.

Am I missing something, or is there some caveat I should be aware of?

It would be useful to know how Skype for Web handles the deletions -- check the requests in your browser's developer tools (you can compare with SkPy by running with SKPY_DEBUG_HTTP=1 set in your environment) to see if there's some extra parameters or a new call being used.

The exception itself might be dubious if 675 is supposed to be a success state -- so far I've only seen error codes used for errors, so any errorCode in the response will throw one.

Thank you! I didn't know about SKPY_DEBUG_HTTP=1. I discovered a few things.
Error 675 means that the message was already removed. Apparently, if you remove a message, it is still returned by getMsgs with an empty content and a 'properties': {'deletetime': '1741249506781'}.

Skype Web uses a different endpoint: https://msgapi.teams.live.com/v1/users/ME/conversations/ instead of https://azwcus1-client-s.gateway.messenger.live.com/v1/users/ME/conversations/, but they seem identical in their functionalities. I'm still using live.com

I've modified my script to skip messages with empty content, and it seems to be working fine now.

About the empty notifications my guess is that they ware sent when deleting an already deleted message. I'm not receiving other complaints.

Although it's called shutdown, it's more like a merge into MS Teams. At least there were claims that they'll migrate user accounts (which is already true to some degree), contact lists (still not done) and even chat history. Meanwhile they're changing the API, the most notable change is client-s.gateway.messenger.live.com (and its aliases) → msgapi.teams.live.com but it's not the only one, see discussions in skype4pidgin and miranda repos. Who knows, maybe this library would be usable (with some minor changes) even when this migration process completes.
