# Delete/Remove

This action deletes documents from a repository by their identifiers. Remove and delete are different names for the same action.

Type: Asynchronous

Parameter Name | Description | Required
--- | --- | ---
`Config` | A base-64 encoded configuration. The configuration parameters that are set override the same parameters in the connector's configuration file. | No
`failedDirectory` | The directory in which the action reports failures. | No
`Identifiers` | A comma-separated list of document identifiers. The documents with these identifiers are removed from the repository. | Yes
`Override_Config_Parameters` | Any other action parameters that you set override settings in the connector's configuration file. For example:
    /action=fetch&fetchaction=...
                 &[Section]Parameter=Value
where `[Section]` (optional) is the name of a configuration file section, `Parameter` is the name of a configuration parameter, and `Value` is the parameter value. | No

## Example

    http://localhost:1234/action=Fetch&FetchAction=Delete
                                      &Identifiers=...

## Response

As this is an asynchronous action, you receive a token in response to the request. A sample response to the action (as retrieved using the `QueueInfo` action) appears below.

The following response shows that one document was deleted successfully.

    <action>
      <documentcounts>
        <documentcount
            added="0"          collected="0"       deleted="1"
            errors="0"         holds="0"           ingestadded="0"
            ingestdeleted="0"  ingestfailed="0"    ingestupdated="0"
            inserted="0"       releasedholds="0"   seen="0"
            task="DIR1"        unchanged="0"       updated="0"/>
      </documentcounts>
      <fetchaction>DELETE</fetchaction>
      <tasks>
        <success>
          PGlkIHM9IkRJUjEiIHI9IkM6XEF1dG9ub215XEZpbGVTeXN0ZW1Db25uZWN0b3JDRlNcZGlyMVxuZXdmaWxlLnR4dCIvPg==
        </success>
      </tasks>
      <token>MTAuMi4xMDUuMzQ6MTIzNDpGRVRDSDotMTgwNDU4NzIxMQ==</token>
      <status>Finished</status>
      <queued_time>2009-Oct-15 16:43:17</queued_time>
      <time_in_queue>0</time_in_queue>
      <process_start_time>2009-Oct-15 16:43:17</process_start_time>
      <time_processing>0</time_processing>
      <process_end_time>2009-Oct-15 16:43:17</process_end_time>
    </action>

If a document cannot be deleted successfully, the document identifier appears between `<failed>` tags and a message explains the reason for the failure:

    <tasks>
      <failed message="File deletion failed: Access is denied.">
        PGlkIHM9IkRJUjEiIHI9IkM6XEF1dG9ub215XEZpbGVTeXN0ZW1Db25uZWN0b3JDRlNcZGlyMVxmaWxlOS50eHQiLz4=
      </failed>
    </tasks>
