## Overview It is possible to input and output data with other systems using "[API](https://pleasanter.org/en/manual/api)". ## Prerequisites 1. To use the "[API](https://pleasanter.org/en/manual/api)", you must create an "[API Key](/en/manual/api-key)". If you access the API from a logged-in browser session, you can use it without specifying an "[API Key](/en/manual/api-key)". 1. The Enabled Parameter in [Api.json](/manual/api-json) must be set to true. ## Related Information <div id="ManualList"><ul><li><a href="/en/manual/api-key">Developer Function: API: Create an API Key</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-record-get">Developer Function: API: Table Operation: Retrieve Single Record</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-record-get-multi">Developer Function: API: Table Operation: Retrieve Multiple Records</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-record-delete">Developer Function: API: Table Operation: Delete Record</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-table-bulk-delete">Developer Function: API: Table Operation: Bulk Delete Record</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-attachment-get">Developer Function: API: Table Operation: Retrieve Attachments</a><span>10.01.2024 up</span></li> <li><a href="/en/manual/api-export">Developer Function: API: Table Operation: Export Table</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-import">Developer Function: API: Table Operation: Import Record</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-group-import">Developer Function: API: Group Operation: Import</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-group-create">Developer Function: API: Group Operation: Create Group</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-group-delete">Developer Function: API: Group Operation: Delete Group</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-group-get">Developer Function: API: Group Operation: Get Group</a><span>10.01.2024 up</span></li> <li><a href="/en/manual/api-site-copy">Developer Function: API: Site Operation: Copy Site</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-site-create">Developer Function: API: Site Operation: Create Site</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-site-get">Developer Function: API: Site Operation: Retrieve Site</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-site-update">Developer Function: API: Site Operation: Update Site</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-synchronize-summaries">Developer Function: API: Site Operation: Summary Sync</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-rebuild-search-indexes">Developer Function: API: Site Operation: Search Index Rebuild</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-mail">Developer Function: API: Email: Send Email</a><span>10.08.2024 up</span></li> <li><a href="/en/manual/api-user-import">Developer Function: API: User Operation: Import</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-user-create">Developer Function: API: User Operation: Create User</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-user-delete">Developer Function: API: User Operation: Delete User</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-user-get-all">Developer Function: API: User Operation: Retrieve User (All)</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-user-get">Developer Function: API: User Operation: Retrieve User (Select)</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-user-update">Developer Function: API: User Operation: Update User</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-dept-import">Developer Function: API: Department Operation: Import</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-dept-get">Developer Function: API: Department Operation: Retrieve Department</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-dept-create">Developer Function: API: Deparment Operation: Create Deparment</a><span>08.14.2024 up</span></li> <li><a href="/en/manual/api-dept-delete">Developer Function: API: Department Operation: Delete Department</a><span>10.01.2024 up</span></li> <li><a href="/en/manual/api-dept-update">Developer Function: API: Department Operation: Update Department</a><span>10.01.2024 up</span></li></ul></article></div><input id="SearchTextHidden" type="hidden" value="" />
