Documentation for possible error codes

[emmanuelatisu]

Is there documentation on all the possible error codes that can be returned?
So far the only thing i could find was in the go sdk errors.go.

Not having all possible error codes makes it difficult to map keygens errors to our own implementation of licensing errors.
Just using the keygen errors is not an option for us since we have the requirement to abstract keygen and seperate it from the rest of our licensing system in case of switching to another provider.

Help finding the documentation would be really appreciated if it exists.
If it doesn't, would it be possible to release documentation on all error codes?

Error codes are dynamic based on various model, authn, authz, and parameter validations in the system. Although we'd love to document all error codes in the future, doing so is a rather huge effort, and so it's not on the roadmap right now. The error codes in the Go SDK are the codes that we specifically need to handle, and most integrations will follow a similar path of only handling the codes that matter to them. You may have some luck searching the code base's test suite, but it won't be exhaustive.

Again, most integrations will not need to handle all error codes, because most integrations only use a small subset of the API. You can simply handle the error codes that matter to your business logic and skip the rest. If one is unknown to you, it likely doesn't matter yet and so can be handled as a general "licensing error" until business logic dictates otherwise.

The codes that absolutely do matter for everybody, like license validation codes are fully documented.
