# Connect the Email integration (born active; presence marker for the send_email tool)

`POST /v1/integrations/connections/email`

Create a born-``active`` presence connection so the ``send_email`` tool
materializes and becomes attachable. There is no credential to collect — the
Nylas API key is platform-level and the sending mailbox is connected via the
separate email OAuth flow. The tool sync is dispatched post-commit.

## Request body

- PlatformConnectionCreate — Body for ``POST /v1/integrations/connections/email``. A credential-less "platform" integration (the Nylas API key is platform-level and the sending mailbox is connected via the separate email OAuth flow). The connection is born ``active`` — there is nothing to authenticate here; it is a presence marker so the ``send_email`` tool materializes and becomes attachable. Only a ``nickname`` is needed.
  - `nickname` string
