RESTCONF: HTTP verbs over a YANG datastore
The URL walks the YANG tree
Choosing the verb: POST, PUT, PATCH, DELETE
Status codes and ietf-restconf:errors
Media types: Content-Type and Accept
Building the JSON body: YANG to JSON
Exam patterns: valid URLs, verbs, and bodies

RESTCONF verbs mapped to datastore operations

Property	POST	PUT	PATCH	DELETE
Datastore operation	Create child	Create or replace	Merge leaves	Remove
Idempotent	No	Yes	No	Yes
Target already exists	409 (data-exists)	Replaced	Merged into	Deleted
Target absent	Created (201)	Created (201)	404 (no target)	404 (no target)
Success code	201 Created	204 (201 on create)	204 No Content	204 No Content
Best suited to	One-shot create	Declarative convergence	Surgical leaf edits	Teardown

Cheat sheet

Cheat sheet

RESTCONF root exposes /data and /operations resources
YANG containers and lists map to URL path segments
The first node and cross-module nodes carry the module prefix
content, depth, and fields query parameters shape retrieval
POST creates a new child data resource
PUT creates-or-replaces the target and is idempotent
PATCH merges partial edits; DELETE removes the resource
RESTCONF status codes: 201, 204, 400, 404, 409
yang-data+json/+xml are the RFC 8040 media types
Content-Type and Accept govern request vs response encoding
Errors are returned as ietf-restconf:errors
IOS-XE enables RESTCONF over HTTPS/443
Native model nests IPv4 under ip/address/primary with mask
Native and IETF/OpenConfig models have distinct URIs
JSON keys must match YANG leaf names exactly
PUT body wraps the target container, module-qualified
