`installations` (installation creation / update) | PARSE_SERVER_EXPERIMENTAL_IDEMPOTENCY_PATHS   | An array of path patterns that have to match the request path for request deduplication to be enabled. The mount path must not be included, for example to match the request path `/parse/functions/myFunction` specify the path pattern `functions/myFunction`. A trailing slash of the request path is ignored, for example the path pattern `functions/myFunction` matches both `/parse/functions/myFunction` and `/parse/functions/myFunction/`. |
