Documented steps
PUT /channels/{channel.id}/permissions/{overwrite.id} where overwrite.id is the role id or user id, with Authorization: Bot <token>
Body: type as an INTEGER — 0 for a role, 1 for a member — plus allow and deny permission bitfields serialized as strings (API v8+ serializes all permissions as strings)
The @everyone overwrite uses the guild id as the role id
Delete an overwrite: DELETE /channels/{channel.id}/permissions/{overwrite.id}
Effective permission order: base @everyone perms -> role perms -> @everyone overwrite (deny then allow) -> role overwrites (all denies, then all allows, aggregated) -> member overwrite (deny then allow)

Known gotchas
type is an integer (0 role / 1 member) while allow/deny are strings — mixing these up is a common 400
ADMINISTRATOR overrides all channel overwrites — you cannot deny anything to an administrator via overwrites
Role overwrites aggregate at the same layer: an allow on any of the member's role overwrites beats a deny on another role's overwrite
Child channels synced to a category follow the category's overwrites, but any change made directly on the child de-syncs it and it stops following the parent
Editing overwrites requires MANAGE_ROLES in that channel
