Single sign-on

Set up or change a workspace's single sign-on

Set up the workspace's single sign-on, or change it; a field left out keeps what is saved for the same protocol. oidc: issuer (read for its discovery document first), client_id, client_secret, scopes (openid email profile by default). oauth2: authorization_url, token_url, userinfo_url, client_id, client_secret, scopes, subject_claim (sub, then id, by default) and email_claim (email). saml: idp_entity_id, idp_sso_url and certificate (the provider's signing certificates, PEM; several while rotating). client_secret and certificate left out keep what is saved. allow_join (false by default) lets anyone the provider signs in join as a member; join_domains limits that to addresses the provider vouches for at those domains.

PUT/workspaces/{workspace}/sso

Moving to another provider (protocol, issuer or entity id) unlinks everyone and stops requiring it. Needs a paid plan. Returns what get_sso does. Recorded as sso.created or sso.updated. Owners only, as people.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: workspace with action configure_sso, and the same inputs
Scope: An access token needs workspace:admin.

Path parameters

Name	Type	Required	Description
`workspace`	string	Yes	The workspace’s name, e.g. “acme”.

Body parameters

Send a JSON object. Names are snake_case, as in responses; the camelCase spelling is accepted too.

Name	Type	Required	Description
`protocol`	string	Yes	How g1t speaks to the provider. One of `oidc`, `oauth2`, `saml`.
`issuer`	string	No	oidc: the issuer, where its /.well-known/openid-configuration lives.
`client_id`	string	No	oidc, oauth2: the client id.
`client_secret`	string	No	oidc, oauth2: the client secret; kept encrypted, never returned. Left out keeps the one saved.
`scopes`	string	No	oidc, oauth2: space-separated scopes.
`authorization_url`	string	No	oauth2: the authorization endpoint (https).
`token_url`	string	No	oauth2: the token endpoint (https).
`userinfo_url`	string	No	oauth2: the userinfo endpoint (https).
`subject_claim`	string	No	oauth2: the userinfo claim that is the person’s stable id; a dotted path works.
`email_claim`	string	No	oauth2: the userinfo claim that is their address.
`idp_entity_id`	string	No	saml: the provider’s entity id (its issuer).
`idp_sso_url`	string	No	saml: where the provider takes requests (HTTP-Redirect, https).
`certificate`	string	No	saml: the provider’s signing certificates, PEM. Left out keeps the ones saved.
`allow_join`	boolean	No	Anyone the provider signs in joins as a member when they first sign in through it. False by default; leave it off for a provider anyone can sign in to.
`join_domains`	array of strings	No	When joining is on, only people whose address the provider vouches for (OpenID’s email_verified, or a signed SAML assertion) is at one of these domains, such as [“acme.com”]. Empty: anyone it signs in.

Status	Code	When
401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change, or a token without the scope it needs.
404	`not_found`	It does not exist, or you cannot see it.
409	`conflict`	The request conflicts with the current state.
422	`invalid`	The input is not valid. `message` says which field and why.
