updateMask "summary" with post {"summary": "New text"}). LocalPost fields: languageCode; summary (the post text); topicType (STANDARD | EVENT | OFFER | ALERT); callToAction {actionType: BOOK | ORDER | SHOP | LEARN_MORE | SIGN_UP | CALL, url}; event {title, schedule{startDate{year,month,day}, startTime{hours,minutes}, endDate, endTime}} — required for EVENT and OFFER; offer {couponCode, redeemOnlineUrl, termsConditions}; media [{mediaFormat: "PHOTO", sourceUrl}]. ALERT posts are restricted to Google-initiated campaigns and are typically rejected. Counts against the 10 edits/min per-profile cap. Local posts live only on the legacy v4 API (mybusiness.googleapis.com) — they were never migrated to v1.

Access also depends on token permissions, quotas, and upstream API limits.
