What you get

Skip the part where your agent gets it wrong

Authentication, the right way. Bearer-token format, key rotation, env-var conventions. Every snippet uses HELTAR_API_KEY from env — never hardcoded, never logged.

Edge cases handled. 24-hour window, template-only re-engagement, media URL expiry, status idempotency, Meta error codes 131047 / 131051 / 131053 — all baked in.

Working code on the first try. curl, JavaScript, Python. No outdated SDKs, no invented endpoints, no missing fields.
