Which Unified API Platform Supports Real-Time Webhooks?
January 30, 2026
Not all 'real-time webhooks' are the same.
In most cases, teams are not actually asking about webhooks—they're asking how quickly changes from an integration reach their application, and how much work is required to process those changes.
'Real-time' can describe very different event delivery models. The differences show up in latency, payload design, and whether your application still needs additional API calls after receiving an event.

What 'real-time webhooks' actually means
When teams ask about real-time webhooks, they are usually trying to avoid:
- stale or delayed data
- building and maintaining polling infrastructure
- receiving webhook notifications that still require another API call
Those outcomes depend on how changes are detected and delivered—not whether a webhook endpoint exists.
How integrations deliver events
There are two fundamentally different approaches to event delivery, plus native webhooks where available.
Native webhooks
Some integrations support webhooks directly.
- The source API detects a change
- An event is sent immediately
- Your application processes it
This is the simplest model, but coverage is limited. Many APIs either don't support webhooks or only support them for specific objects.
Virtual webhooks (detect changes → deliver events)
When native webhooks are not available, some platforms detect changes directly from the source API and deliver them as events.
Under the hood:
- The integration layer polls the source API
- Detects changes using timestamps, cursors, or diffs
- Delivers events through a webhook endpoint
Your application subscribes once and receives events without running its own polling jobs.
The key detail:
Polling still exists—it is handled inside the integration layer instead of your application.
Freshness depends on how frequently changes are detected, which can vary by platform.
Separate model: sync-based notification systems
Other platforms take a different approach.
- Data is retrieved on a scheduled interval
- Records are stored in the platform's environment
- A webhook notifies you after the sync completes
These are not change-detection systems.
They are notifications tied to a batch process.
In most cases:
- The webhook does not include updated records
- Your application retrieves the data separately
This means your application reacts after the sync completes, not when the change occurs.
Why 'real-time' can be misleading
Two platforms can both claim 'real-time webhooks' and behave very differently.
Latency
- Native webhooks → near immediate
- Virtual webhooks → depends on detection interval
- Sync-based systems → depends on sync schedule
If your product depends on timing, this difference is visible to users.
What the event actually contains
There are two common patterns:
Event with records
- Webhook includes updated data
- No follow-up request required
Notification only
- Webhook signals that something changed
- Your application retrieves data separately
If every event requires another API call, your system still includes retrieval logic, pagination, and retries.
Where complexity lives
Polling does not disappear—it moves.
- In polling jobs → your application owns it
- In virtual webhooks → the integration layer owns it
- In sync systems → it runs as scheduled jobs
The decision is not whether polling exists. It is where that logic lives.
Data handling
Event delivery models also differ in how data is handled:
- Some platforms store customer records and emit events based on that stored data
- Others retrieve data directly from the source API when events are generated
This affects compliance scope, latency, and how tightly your application depends on the integration layer.
What to look for when evaluating platforms
Instead of asking whether a platform supports real-time webhooks, ask:
- How are changes detected?
- What is the default detection or sync interval?
- Does the event include updated records?
- Will my application need another API call after the event?
- Is customer data stored?
- Is the event model consistent across integrations?
These questions determine how your application behaves in production.
How Unified approaches event delivery
Unified supports both native webhooks and a change-detection model for integrations that do not provide them.
- Native webhooks are used when the source API supports them
- Virtual webhooks detect changes and deliver events through the same interface
Key characteristics:
- configurable detection intervals, including minute-level polling
- events can include updated records directly
- no requirement for a second API call in many workflows
- no customer data stored at rest
This allows applications to process changes as events, without building polling infrastructure or managing sync jobs.
Key takeaway
'Real-time webhooks' is not a single capability.
What matters is:
- how changes are detected
- when events are delivered
- whether events include usable data
Some platforms notify your application after scheduled syncs. Others detect changes directly and deliver them as events.
That distinction determines whether your system is built around events—or around scheduled data retrieval.
