End a member's access to the organization without deleting them

POST /api/auth/members/{organizationId}/{userId}/deactivate

End a member's access to the organization without deleting them — people are never deleted, because the journal names every actor.

From their next token they hold nothing here, the organization drops off their list and entering it is refused; their roles are kept for a reactivation. An optional reason (at most 500 characters: 400 InvalidReason beyond) is recorded with it. 403 AdminRequired for anyone but an owner or admin, MembershipDeactivated for a caller whose own access has ended, OwnerRequired for an admin deactivating an owner; 404 NotAMember; 409 CannotDeactivateSelf, and 409 LastVerifiedOwner for the organization's last active owner with a verified email — every organization keeps one, so elect another verified owner first. Appends auth.member-deactivated. Idempotent by state: deactivating a member who is already deactivated is acknowledged and appends nothing.

Access

Requires a signed-in session: An active owner or admin of the organization, checked against its membership by the route (the person's BetterAuth session)

How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.

Retries

Idempotent by state: deactivating a member who is already deactivated is acknowledged and appends nothing.

Why every write carries a key: Idempotency and retries.

Facts appended

auth.member-deactivated

What a fact is: Facts and the journal.

AI agent tool

No agent tool. Ending a member's access is an owner's or admin's decision in Settings › Users, never an agent's; it answers a person's BetterAuth session only.

Connecting an agent: AI agents.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`400`

Refusal	What it means	What to do
`InvalidReason` reason	The reason given is not one this call accepts.	Fix the request body.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`AdminRequired`	Only an owner or admin of the organization may do this.	Ask an owner or admin.
`MembershipDeactivated`	Your own access to this organization has ended.	Ask an owner or admin to reactivate you.
`OwnerRequired`	Only an owner may do this to an owner.	Ask an owner.
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`404`

Refusal	What it means	What to do
`NotAMember` userId	The person is not a member of this organization.	Check the organization, or invite them first.

`409`

Refusal	What it means	What to do
`CannotDeactivateSelf`	You cannot deactivate your own membership.	Ask another owner or admin.
`LastVerifiedOwner` reason	This would leave the organization without an active owner with a verified email.	Make another verified member an owner first.
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Send the same request again shortly.
