Exchange public token for an access token

Exchange a Link public_token for an API access_token. Link hands off the public_token client-side via the onSuccess callback once a user has successfully created an Item. The public_token is ephemeral and expires after 30 minutes. An access_token does not expire, but can be revoked by calling /item/remove.

The response also includes an item_id that should be stored with the access_token. The item_id is used to identify an Item in a webhook. The item_id can also be retrieved by making an /item/get request.
