Real-time data without polling or cron jobs
Apideck provides native webhooks for some providers, but relies on polling for others. Virtual webhooks poll every 24 hours.
Unified.to delivers updates using native and virtual webhooks, with data retrieved directly from source APIs instead of relying on scheduled polling. You don't manage jobs, retries, or state tracking. Unified.to emits consistent, structured events when data changes—no stale cache or delay.
Data architecture differences
| Area | Apideck | Unified.to |
|---|---|---|
| Data delivery | API + webhooks + polling intervals | Native + virtual webhooks |
| Schema approach | Common models + raw mode | Structured schemas across integrations |
| Data pipelines | Requires custom ingestion logic | API, webhooks, or database sync |
| Data storage | Stores some metadata | No customer data stored |
One schema across systems—not just common fields
Apideck maps common fields per category (e.g. employees, companies). If you need full data access, you toggle Raw Mode and manage the transformation.
Unified.to provides deep, unified schemas for every object it supports—plus passthrough fields and access to raw payloads. Whether you're working with ATS, CRM, HRIS, or ticketing data, you get predictable fields, enums, and associations.
This unlocks complex workflows and AI use cases without losing flexibility.
Built-in database sync for structured records
Apideck supports webhooks and streaming via its API. You'll need to manage your own ingestion logic to write to a database.
Unified.to offers first-class Database Sync:
- Connect your Postgres, MongoDB, or MySQL instance
- Stream real-time records by object type
- No ETL, no transformation
Data lands normalized and current—ready for dashboards, agents, or analytics.
Zero data stored—no security liability
Apideck stores some customer data (like connected user info) even if it doesn't cache payloads. You'll need to audit what's stored and where.
Unified.to doesn't store end-user data or credentials. Requests proxy through to the source system in real time. You stay in control of where data flows and how it's handled.
Developer-first experience
Apideck offers SDKs, a visual explorer, and a well-documented sandbox for testing integrations. It's strong for teams launching embedded marketplaces.
Unified.to is built for engineers:
- SDKs in 7+ languages
- Open source Connect Component for React/Vue/Angular
- Daily SDK updates
- Postman and OpenAPI support
- Fast integration turnaround
Product teams use Unified.to to replace brittle ETL, cut integration time, and power complex, AI-native features.
What customers say on G2
G2 isn't a spec sheet, but it's a useful signal for onboarding experience, support quality, and where teams hit limitations in production. As of January 14, 2026, Apideck Unify is rated 4.9/5 from 51 reviews, and Unified.to is rated 5.0/5 from 23 verified reviews.
Apideck Unify (themes from G2 reviews)
What users like
- Responsive support and proactive communication.
- Ease of use and fast build/implementation.
- Unified API layer (common reason teams choose it for multi-system coverage, including HRIS/CRM).
- Clear documentation and 'quick to get started' experience.
- Pricing described as accessible/affordable in multiple reviews.
What users flag
- Connector-by-connector API limitations (some resources supported, others missing).
- Data / feature gaps (missing endpoints, advanced features, or third-party APIs still not available).
- Complexity from product layers/limitations for some implementations.
How to interpret this: Apideck's reviews read like 'fast to implement, strong docs/support,' with the main friction being connector coverage and endpoint depth. Unified's reviews emphasize production DX (observability + real-time patterns + support throughput) once integrations move from 'integration project' to 'core infrastructure.'
