What's available
Everything you need to integrate
Full programmatic access to every nsxia module, secured by the same identity layer your users rely on.
REST API
Full REST API covering all modules — Finance, CRM, Uptime, Sign, HR, Inventory, and more. JSON over HTTPS. Versioned at /v1/.
Webhooks
Receive real-time event payloads to your endpoint when records change. Configurable retry logic and HMAC-signed payloads.
API Keys
Create scoped API keys per organisation from your dashboard. Set per-key permissions and rotate them without downtime.
Webhooks Replay
Re-deliver any webhook event from the last 30 days directly from your dashboard. Never miss a critical integration event.
Quick start
Simple, predictable API
Standard REST conventions. All responses are JSON. All endpoints require an Authorization header.
curl https://nsxia.com/api/v1/finance/invoices \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json"const res = await fetch("/api/v1/crm/contacts", {
method: "POST",
headers: {
"Authorization": `Bearer ${apiKey}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
name: "Acme Corp",
email: "[email protected]",
type: "company",
}),
});
const contact = await res.json();import hmac, hashlib
def verify(payload: bytes, sig: str, secret: str) -> bool:
expected = hmac.new(
secret.encode(), payload, hashlib.sha256
).hexdigest()
return hmac.compare_digest(expected, sig)Base URL
Module paths prefixed accordingly — /v1/finance/invoices, /v1/crm/contacts.
Authentication
API keys are scoped to your organisation. Create and revoke them from your account dashboard. Use separate keys per environment.

- HMAC-SHA256 signed — verify before processing
- Automatic retries with exponential backoff (up to 24 h)
- Configurable per-endpoint event filtering
