# Utility endpoint to submit a batch of sequenced, dependent requests.

`POST /sequence`

The requests are guaranteed to be performed sequentially in the order given in the request and will abort if any request does not return a status-`2xx` response.
For example, this can be used to ban and delete all of a user's messages by sequencing the ban followed by the delete_all: if the ban fails (e.g. because permission is denied) then the delete_all will not occur. The batch body and response are identical to the `/batch` endpoint; requests that are not carried out because of an earlier failure will have a response code of `412` (Precondition Failed)."
