# InitialID

The ID of the DREINITIAL index action to process, when multiple index actions are sent.

In a system with an array of DIHs, a DREINITIAL index action might be sent to a server multiple times. If there was a delay in sending a subsequent index action, documents might be deleted that in fact arrived after the original DREINITIAL.

The `InitialID` parameter ensures that when a DREINITIAL index action is received by a server multiple times, only the first DREINITIAL index action identified by the `InitialID` is processed, and the rest are ignored.

The Content component `GetStatus` action reports the `InitialID` of the last DREINITIAL that it processed, which allows you to check whether the DREINITIAL index action was completed.

Actions: | DREINITIAL
Type: | String
Default: |
Example: | `DREINITIAL?InitialId=123654`
