Sumsub — Create Level

Builds an ApplicantLevel JSON payload from a compact spec, POSTs (or PATCHes) it to the Sumsub API, and reports the resulting name / id.

Endpoints

Method	Path	When
`POST`	`/resources/applicants/-/levels`	Create a new level. Body must NOT include `id` or `key` — server assigns them.
`PATCH`	`/resources/applicants/-/levels`	Update an existing level (by `id` in body). A top-level field missing from the body keeps its stored value; a field you send replaces the stored one whole (see step 6).
`GET`	`/resources/applicants/-/levels/{id}`	Read one level. Use this to verify what landed (tenant gates may silently drop fields) or to resolve `name` from a known `id`.
`GET`	`/resources/applicants/-/levels`	List all levels (`list_levels.sh`; use to reuse existing levels before creating duplicates).

Body: ApplicantLevel. Returns the persisted level with id, createdAt, audit trails.
