//
// See info about tokens created for/by your account.
//
// By default, the items will be returned in descending chronological order of latest used time (latest -> oldest).
//
// If the "order" parameter is set to "created", then items will be returned in descending chronological order of creation time (newest -> oldest), with sequential IDs (bigger = newer).
//
// The returned Link header can be used to generate the previous and next queries when paging up or down.
//
// Example:
//
// ```
// <https://example.org/api/v1/tokens?limit=20&max_id=01FC3GSQ8A3MMJ43BPZSGEG29M>; rel="next", <https://example.org/api/v1/tokens?limit=20&min_id=01FC3KJW2GYXSDDRA6RWNDM46M>; rel="prev"
