Store card or network token data in the Payrails Vault and receive aliases for it.

The response returns one entry per requested record, in the order of the request, in the same
representation the record retrieval endpoints return. A record that fails validation carries an error
and does not fail the rest of the request.

A request holds at most 50 records. One carrying more is rejected with 413 and no record is stored.

Repeating a request stores new records and returns new aliases. The endpoint provides no idempotency.

This endpoint is served on the Payrails Vault host and accepts a Vault access token. It is available by
request and requires an approval by Payrails.
