MSC0000: M_CAPABILITY_NOT_ENABLED error code for when capability is not enabled on an API endpoint
The capabilities negotiation feature in the Client-Server API provides a mechanism for clients to discover whether specific capabilities are available to a user.
However, the endpoints that use capabilities do not currently specify what error response a client should expect if they try to use an API that does not have the capability enabled for the user.
I believe this is an omission in the current spec that should be addressed for existing capabilites and be checked for future MSCs that use capabilities.
For background: this MSC originates from a spec PR that has since been closed.
Proposal
Define a new other error code of M_CAPABILITY_NOT_ENABLED.
Define the following behaviour for existing API endpoints that use capabilities:
| Capability | Endpoint(s) | Current spec | Proposed behaviour |
|---|---|---|---|
m.change_password |
POST /_matrix/client/v3/account/password |
Not defined | Return 403 with M_CAPABILITY_NOT_ENABLED if m.change_password.enabled is false |
m.profile_fields |
PUT /_matrix/client/v3/profile/{userId}/{keyName} DELETE /_matrix/client/v3/profile/{userId}/{keyName} |
403 for PUT. Maybe 403 for DELETE. Error code not specified for either |
Return 403 with M_CAPABILITY_NOT_ENABLED if: m.profile_fields.enabled is false; or, m.profile_fields.disallowed contains {keyName}; |
m.set_displayname |
As per m.profile_fields |
As per m.profile_fields |
