configure it in the API or UI.
External ID's can be used to link a document or template to an external
system and identify them via webhooks, etc.

(publishing) a document using the API.
Additionally returns the signing link for each recipient
when working with recipient API endpoints and returns
the document object including recipients when sending
documents via API.

documents
Other changes:

Extracts the API implementation to a package so we can
potentially reuse it across different applications in the
event that we move off using a Next.js API route.
Additionally tidies up the tokens page and form to be more simplified.
