# Create a custom role

> Signed-in members only.

<api-operation method="POST" path="/v1/roles">
<template v-slot:docs="">

The name must not be a fixed role's name, compared after Unicode normalisation (so look-alike forms of `Admin` are refused). Every permission must be in the catalogue, and the caller must have each one.
