Platform & API Integrations
Connect your product to the systems it depends on — CRMs, mailboxes, calendars, enrichment and messaging providers — with two-way sync, idempotent webhooks, and audited credentials.
Most products live or die by the systems around them — the CRM, the mailbox, the calendar, the enrichment and messaging providers. nuvio builds API integration and system integration that holds up in production: pluggable adapters behind one interface, two-way sync that never duplicates records, idempotent webhooks, and encrypted credentials you can audit. We treat third-party APIs as untrusted, rate-limited, occasionally-wrong dependencies, and we wire workflow automation and AI integrations so a failing provider degrades one feature instead of taking down the app.
Pluggable provider adapters behind one interface
We model every external system as a category with a swappable implementation: a lead source, a mail and calendar provider, a sending transport, a domain registrar, an enrichment provider. Each is a small interface — connect, fetch, send, verify — so the app code never knows which vendor is behind it. A connection record stores the provider, its category, status, and encrypted credentials, and the rest of the system talks to the interface, not the brand. That separation is what lets you swap one enrichment vendor for another, add a second sending transport, or run two CRMs side by side without rewriting business logic. New integrations become a new adapter plus a row, not a project. It is the difference between a few hard-wired calls and a real integration layer.
Two-way sync that never duplicates records
Pulling data from third-party APIs cleanly is harder than it looks: providers paginate, change, and resend. We run delta sync against a per-resource cursor stored in your database, so every run picks up exactly where the last one stopped. Incoming records are written with insert-on-conflict upserts keyed on the source's natural id, which makes a sync idempotent — re-running it can never create a duplicate, only update what changed. Writes back to the provider carry the same guarantees. Each run closes by recording an audit entry and, where it matters, a user-facing notification, so an operator can always see what synced, when, and whether it succeeded. The result is a mirror you can trust as a source of truth rather than a best-effort copy.
Webhooks, idempotency, and reliable inbound events
Real-time integration means accepting events you did not ask for: delivery and bounce callbacks, calendar changes, inbound replies, provider state transitions. We verify each webhook's signature before trusting it, store the raw payload for audit and replay, and dedupe on the provider's event id so a redelivered event is processed once. Events drive state — a hard bounce suppresses an address, a confirmed slot books a meeting, a delivery callback advances a message — through the same job queue as everything else, so an inbound webhook and an operator click follow identical, observable paths. Where a provider supports push, we use it; where it only supports polling, we fall back to scheduled delta sync. Either way the downstream behaviour is the same.
OAuth, tokens, and credentials you can audit
Most integrations are gated by OAuth, and tokens are the part teams get wrong. We build a token broker per provider that holds the refresh token, mints short-lived access tokens on demand, and refreshes transparently before expiry, so a sync never fails mid-run on a stale token. Every secret — OAuth tokens, API keys, registrar credentials — is encrypted at rest with envelope encryption; the database holds ciphertext, never plaintext, and connections expose status, not keys. Connect, reconnect, expire, and revoke each emit an audit event, and a disconnected account raises a notification telling the operator exactly which integration needs attention. This is what makes third-party APIs safe to grant scoped, per-tenant access without a credentials sprawl you cannot reason about.
Observability and cost across every provider call
An integration you cannot see is an integration you cannot operate. We record every outbound call to an external provider — the operation, http status, latency, retry count, whether it was rate-limited, and any metered cost or credits consumed — against the same trace id that threads the originating request, job, and downstream work. That turns a vague 'the integration is slow' into a query: which provider, which operation, how often it is throttling, what it is costing per tenant. The same telemetry feeds budget caps and spend alerts, so a runaway integration or a provider price change surfaces as a number, not a surprise invoice. This observability is what keeps workflow automation and AI integrations debuggable once they are doing real volume.
- Pluggable adapters per provider category — lead source, mail/calendar, sending transport, enrichment, domain registrar — behind one interface
- Delta sync with per-resource cursors and insert-on-conflict upserts keyed on the source's natural id, so re-runs never duplicate
- Signature-verified, idempotent webhooks deduped on provider event id, with raw payloads stored for audit and replay
- Per-provider OAuth token brokers with transparent refresh and envelope-encrypted credentials at rest
- Provider-call telemetry: status, latency, retries, rate-limit flags, and metered cost per operation, joined by trace id
- Sync audit and operator notifications on every run, reconnect, failure, and disconnected account
- A real integration layer where adding or swapping a provider is a new adapter and a config row, not a rewrite
- Two-way sync you can trust as a source of truth — idempotent, auditable, and free of duplicate records
- Visibility into every third-party call, so slow, throttling, or costly providers are a query instead of a guess
Use cases
A two-way sync engine mirrors accounts, contacts, deals, mail, and calendar from a CRM and mailbox into your database, with per-resource cursors and natural-key upserts so repeated runs only update what changed and never create duplicates.
One sending interface fronts several transports — transactional email, SMS, and chat — with per-channel caps, delivery and bounce webhooks driving state, and a hard bounce automatically suppressing an address everywhere it could be contacted.
Lead-source and enrichment providers sit behind a common adapter, so the app requests enrichment without knowing the vendor. Swapping or adding a provider is one adapter and a credential row, with cost tracked per call.
