Nobody is a member of a team Studio by default: an invitation makes one. This page says how an owner invites someone, how the first owner gets in, and what an invitation can and cannot do.

What you get

A one-time link for one email address and one role. When that person opens it and logs in with that email, verified by the identity provider, they become a member with that role.

Context and versions

A hosted Studio (the Studio Server) with an OpenID Connect provider, from 4.2.1. The local Studio has no members and no invitations.

Prerequisites

• An owner, to invite from the Studio or the API; or a shell on the server's machine, for the first owner.
• The person has an account at the provider, with a verified email address: the invitation checks the email the provider says is verified, never one typed by hand.

Where to run the commands

• In the Studio: your name in the header, then Members… (owners only).
• Through the API: from any machine, with an owner's Bearer token.
• The first owner: on the machine of the studio app, where the server's configuration is (on Clever Cloud, in clever ssh), in the engine repository's folder.

Steps

1. The first owner comes from the command line, since nobody can invite yet:

   # on the studio app's machine, in the engine repository (on Clever Cloud: clever ssh, then cd "$APP_HOME")
   npm run studio-server -- invite --email you@example.fr --role owner

   It prints the link. The configuration comes from --config <file> or from STUDIO_CONFIG_JSON, which the shell of clever ssh already has. From the release archive the command is npx quest-n-click-studio-server invite --email you@example.fr --role owner --config studio.config.json.

2. Any other member, in the Studio: Members…, then the Invite form. Type the email (verified at the provider), choose the role (owner, dev or reviewer; dev is preselected), and click Create the invitation link. The link appears with a Copy button.

   Through the API, as an owner:

   # anywhere, with an owner's token
   curl -X POST -H "Authorization: Bearer $TOKEN" -H "content-type: application/json" \
     -d '{"email": "lea@example.org", "role": "dev"}' https://studio.example.fr/api/invitations

   It answers {"link": "https://studio.example.fr/auth/login?invite=…", "expiresInDays": 7}.

3. Send the link yourself (the Studio sends no email): by chat, by mail. It is shown once; only its hash is stored.

4. The person opens the link and logs in at the provider with that email. On the way back they are a member with the invited role. See Starting as an invited dev.

Expected result, and how to check it

• In Members…, the person is listed with their role; the invitation leaves "Invitations not used yet".
• The audit log shows invited (who invited whom, with which role), then joined as <role> (invitation-accepted).
• As them, GET /auth/me answers their role.

The invitation's rules

• 7 days, then it no longer works.
• Used once. A second use, by anyone, does nothing.
• For one verified email. The email the provider gives must be the invited one (compared without case), and the provider must say it is verified.
• It gives the role it names. Accepting an invitation replaces the role the person had, except that the last owner cannot lose the owner role this way.
• A refused invitation does not stop the login: the person is logged in but not a member, and sees the page "Access not granted", "Ask an owner of the project for an invitation." The audit log records invitation-refused with the reason (the invitation is not valid, the invitation is for another verified email, or the last owner stays an owner).

Guarantee · invitation-once-verified-email · referenced · scope self-checked by the author (AI), not reviewed An invitation is used once, and only by a person whose verified email is the one it names.

Limit · invitation-no-revoke A pending invitation cannot be withdrawn: there is no route, in the Studio or the API, to cancel it. It expires after 7 days. If a link leaked, wait it out, or remove the person once they joined (see Managing members). There is no command to list invitations either, other than GET /api/members (its invitations: email, role, expiry) and the Members panel.

Common errors

Symptom	Cause	Fix
The person logs in and sees "Access not granted"	The invitation expired, was used, or their verified email differs	The audit log says which (invitation-refused, reason). Invite again with the email the provider has
`email` is required (400)	The address is empty or malformed	Give a full address
`role` is owner, dev or reviewer (400)	Another role name	Use one of the three
usage: studio-server invite --email <email> --role <owner|dev|reviewer> --config <file> (exit 2)	A flag missing, or a flag where a value belongs	Give both flags with values
this login has expired or was already used: start again (400)	The login page was left open more than 10 minutes, or reloaded	Open the invitation link again

Files or data changed

A row in the database (studio_invitations: the email, the role, the hash of the token, its expiry), then a member row when it is accepted; two audit lines. No game file.

Recovery or going back

A wrong role is changed in Members… (see Managing members). A person who should not have joined is removed there.
