403 Forbidden

The credential isn’t allowed to do this. error.code says why. An account or project the credential doesn’t cover is 404 not_found, not 403.

Example payload: access_denied (The credential isn't allowed to do this to this record)
{
"error": {
"code": "access_denied",
"message": "Access denied"
},
"meta": {
"request_id": "abc123"
}
}
Example payload: insufficient_scope (The credential lacks the permission this endpoint requires)
{
"error": {
"code": "insufficient_scope",
"message": "Insufficient scope",
"details": {
"required_scope": "faults:write",
"token_scopes": [
"faults:read",
"insights:read"
]
}
},
"meta": {
"request_id": "abc123"
}
}
Example payload: requires_user_token (The endpoint records who acted, and an account token has nobody)
{
"error": {
"code": "requires_user_token",
"message": "This endpoint records the person who acted, so it requires a user credential rather than an account token"
},
"meta": {
"request_id": "abc123"
}
}
Example payload: project_restricted (A project-restricted credential cannot create a project)
{
"error": {
"code": "project_restricted",
"message": "Project-restricted tokens cannot create projects"
},
"meta": {
"request_id": "abc123"
}
