If you renamed a source you remove section, you need to delete the content of the source. Otherwise the source entries are orphaned and “float around” and will be seen on the dashboard or inside the global search results.
An index, and therefore its content, can be deleted with this call:
/api/deleteIndex POST
Body:
{
"indexName":"FirstSteps"
}
We recommend you to use Postman for such administrative tasks.
You need to be authenticated as Admin before you can execute this request.
