Add a user directly to a project
const url = 'https://example.com/v1/projects/example/memberships';const options = { method: 'POST', headers: {Authorization: 'Bearer <token>', 'Content-Type': 'application/json'}, body: '{"userId":"example","email":"example","role":"viewer"}'};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request POST \ --url https://example.com/v1/projects/example/memberships \ --header 'Authorization: Bearer <token>' \ --header 'Content-Type: application/json' \ --data '{ "userId": "example", "email": "example", "role": "viewer" }'Names the person by exactly one of userId and email (matched as the runtime matches emails when it adds a person); someone who is not a person of this tenant, or was removed from it, is refused with 404 identity-user-not-found. Adding a role the member already holds answers 201 with the existing record; another role, 409 membership-exists naming the role they hold (details.role), which is kept: use PATCH to change it.
Authorizations
Section titled “Authorizations”Parameters
Section titled “Parameters”Path Parameters
Section titled “Path Parameters”ProjectId — opaque branded string.
Header Parameters
Section titled “Header Parameters”Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per docs/API-ROUTE-CONVENTIONS.md §3.1). A retry sent while the first request still runs is answered 409 idempotency-key-in-flight with Retry-After, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets 409 idempotency-key-replay-withheld, with the first request’s status and when it succeeded (from 0.1.5).
Request Bodyrequired
Section titled “Request Bodyrequired”Exactly one of userId and email names the person.
object
The person’s email, as the tenant has it.
A role to give on a project: owner, admin, editor or viewer, each including the ones after it. member is refused (400): give viewer.
Responses
Section titled “Responses”Membership added.
object
Role on a project, as read. member is only read, on a role given before it was retired: it grants what viewer does, and writes refuse it.
