Create a mail folder
Creates a folder in the mailbox.
POST
/v1/folders
Permission
The key must be granted mail.folders.write
A key without it gets 403 insufficient_scope, with the missing permission named in details.
Request body
| Field | Type | Description |
|---|---|---|
name required |
string | Shown in webmail and over IMAP. Must be unique among its siblings. |
parent_id |
string | Nests the folder inside another. Omit for a top-level folder. |
Request

-X POST \
-H "Authorization: Bearer vak_live_..." \
-H "Idempotency-Key: $(uuidgen)" \
-H "Content-Type: application/json" \
-d '{ "name": "Invoices", "parent_id": null }'Idempotency-Key is required on every write. Retrying with the same key returns the original response rather than repeating the operation, so a timeout is something you retry rather than something you investigate.
