Query and mutate Sanity content

domain: sanity.io · 4 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

Reads: GROQ via /v{date}/data/query/{dataset}?query=*[_type=='post']{...} (CDN endpoint for prod)
Writes: POST /data/mutate/{dataset} with mutations array (create/patch/delete) and a write token
Use transactions: all mutations in one call are atomic
References: {_type:'reference', _ref: id}; images upload via /assets/images first

Known gotchas

apicdn.sanity.io is cached (fast, eventual); api.sanity.io is fresh — query the right host for the job
Patches on missing documents fail the whole transaction — use createIfNotExists for upserts
GROQ injection: never interpolate user input into queries; use parameters ($var)
