const url = 'https://example.com/v1/projects/example/memberships';const options = { method: 'POST', headers: {Authorization: 'Bearer <token>', 'Content-Type': 'application/json'}, body: '{"userId":"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", "role": "viewer" }'Idempotent on (projectId, userId) — re-adding an existing member with a different role does NOT overwrite; use PATCH for role changes.
