callback is very special for the two following reasons:
- It is never called directly by an application but by a single-use link that is generated by another API (e.g. subscribe) in order to be integrated in various contexts such as email or SMS.
- It does not require a key parameter.
It is the reason why the actions that it performs depend on what API has generated the link and then the call:
- In case of a link build by subscribe, it finalizes the subscription process.
- In case of a link build by password_reset, it finalizes the password reset process.
See hereinafter the specific errors depending on those contexts.
