The SharpSpring (Constant Contact Lead Gen & CRM) Open API — a single HTTPS POST endpoint that accepts a JSON envelope of method, params and id, very similar to JSON-RPC. Version v1 resolves timestamps against the Company Profile time zone; v1.2 handles all timestamps in UTC. Credentials are an account ID and secret key passed either as query-string parameters or as the X-Account-Id header plus an Authorization bearer token. Documented limits are 50,000 requests per day, 10 queries per second, and 500 queries per request.
