Send your API key in the Authorization header: Authorization: Bearer . > Every error response from /v1 is JSON: { "error": { "code", "message", "meta" (optional) }, "request_id" }. Branch on error.code; use error.message only for logs. > A 429 response carries a Retry-After header, in seconds, when the limit has a known wait. Authenticated responses can carry X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset for the per-minute request budget your SocialAPI account shares across every API key (see /guides/rate-limits). > Paginated list endpoints return next_cursor, at the top level or inside pagination (see /guides/pagination). Pass it as the cursor query parameter to get the next page. An absent or empty next_cursor means you have the last page. > Treat every ID as an opaque string: do not parse it or assume a format. > Support differs by platform and by operation. Check /platforms/overview before assuming an operation works on a platform. An unsupported operation returns 501 with error.code resource.not_supported. # Reply to a review > Posts a public reply to a review on the platform (Google Business Profile, App Store Connect).
