Delete a published version

No credentials, or credentials that name nobody: none were sent, or the token is not a valid one. Nobody was resolved, so there is no caller to be forbidden.

You are signed in and may not do this. Three different things answer 403, and the body does not say which:

• your role lacks the permission — reading needs the one to view bots, every write the one to edit them;
• the brand is disabled or locked, on any operation;
• the brand's subscription has expired, on a write. Reading still works.

No such bot, or not yours. The two answer identically, on every operation, whatever else may be wrong with the bot.

The version is the bot's most recent publication, and nothing was deleted, under the code version_is_the_most_recent_publication. A version the caller cannot read answers 404 instead, whichever of the two it is.

Too many requests. Every call counts, reads included — the limit is on how fast you call, not on how much you change. It is 40 a second, counted per member rather than per account, so two people generating at once each get their own.
