We have not published a fully documented public HTTP API on this domain yet. What we ship frequently are tailored integrations: internal REST services, queues, webhooks and middleware layers between your systems.
API key sent on every request header.
REST with JSON. Paginated responses where applicable.
1,000 requests/hour per key. Limits surfaced via response headers.
# Create an event curl -X POST https://api.cliente.example/v1/events \ -H "Authorization: Bearer <token>" \ -H "Content-Type: application/json" \ -d '{"type":"order.paid","id":"evt_123"}'
Custom services with API keys or OAuth2, depending on context.
Signed ingestion, retries and deduplication — production patterns from day one.
Specs shared in a private channel (OpenAPI when it helps).
When a public Square² API exists, this page will ship versions, rate limits and official examples. Until then, start from the general docs and a technical conversation with us.
