# Change Email

`POST /api/auth/change-email`

## Request

- Base URL: `https://api.usecreed.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.usecreed.com/api/auth/change-email`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/usecreed/apis/creed-api/docs/api/auth/change-email/post.ts> (a function with typed inputs; its response is checked against the schema)

Change the caller's email to this Apple/Google account. The app first
attaches the login with Supabase's `linkIdentity`; this then makes it the
account's only login and its email the main one, in one transaction.

Safe to call again: if an earlier call failed, the login is still attached
and this finishes the change.
