# Webhooks vs polling for funding events

 When to use webhooks and when to poll for funding events, with a clear trade-off table on latency, reliability, replay, and complexity.

 Webhooks and polling are two ways to get funding events into your system. Polling means your code asks for new events on a schedule. Webhooks mean the events are pushed to you the moment they land. The right choice depends on how fast you need to react and how much you want to operate.

This guide gives plain definitions of each, lays out the trade-offs, and ends with a decision table so you can pick without guessing.

## TLDR

- Polling is pull: your code asks the API for new funding events on a schedule. Webhooks are push: the API sends each event to your endpoint as it lands.

- Webhooks win on latency. A webhook fires within moments. A poll is only as fresh as your interval.

- Polling wins on simplicity. There is no endpoint to host, sign-check, or keep online, and backfilling a date range is one query.

- The common answer is both: webhooks for fast reaction, a periodic poll for backfills and as a safety net.

## What is polling?

Polling is when your code asks the API for new funding events on a fixed schedule. You run a job every few minutes or every hour, request anything new since your last check, and process what comes back.

It is the simpler model to build. You already know how to call an endpoint and loop. There is no public URL to host and no incoming traffic to secure.

The cost shows up in two places. Your data is only as fresh as your interval, so a funding event can sit unseen until your next run. And most of your calls return nothing new, because events do not arrive on your schedule.

## What are webhooks?

A webhook is when the API sends each new funding event to your endpoint the moment it is ready. You register an HTTPS URL once, and from then on the events come to you. No schedule, no empty calls.

This is push instead of pull. Instead of asking “is there anything new?” over and over, you wait and react when a real event arrives. You can see exactly how Datahyena does this on the [webhooks page](https://datahyena.com/webhooks?utm_source=marketing&utm_medium=blog&utm_campaign=webhooks-vs-polling-for-funding-events).

The cost is that you now run a service. You host an endpoint that stays online, verify that each request is genuine, respond quickly, and handle the occasional repeat delivery. More moving parts, in exchange for speed.

## How much faster are webhooks?

A webhook fires within moments of a funding event being ready. Polling is only as fresh as your interval, so the delay is built into your schedule.

The math is direct. If you poll once an hour, a round that resolves one minute after your last run waits almost a full hour before you see it. Cut the interval to every minute and you spend most calls fetching nothing, while still trailing real time by up to a minute.

For funding, that gap matters. The value of a round decays in weeks, and the first touch lands best within one to two weeks of the announcement. Being an hour late rarely loses a deal on its own, but the habit of being late compounds across every event. We covered the timing case in [How to track funding rounds in real time](https://datahyena.com/blog/how-to-track-funding-rounds-in-real-time?utm_source=marketing&utm_medium=blog&utm_campaign=webhooks-vs-polling-for-funding-events).

## What about reliability and missed events?

Both models can miss events, and each has its own recovery path. The question is what happens when something breaks.

With polling, a failed run is easy to recover from. Your next call asks for everything since your last successful checkpoint, so a missed window heals itself on the following run. As long as you track a cursor or a date, you cannot permanently lose an event.

With webhooks, a delivery can fail if your endpoint is down or slow. The safeguard is on the sender’s side. Datahyena retries a failed delivery several times with backoff, and you can replay any past delivery from the dashboard once your service is healthy again. Each delivery carries a stable id so you can ignore repeats.

The honest gap in webhooks is a long outage. If your endpoint is down past every retry, those events will not arrive on their own. That is the case a periodic poll covers: run one over a date range and backfill anything the webhooks missed.

## How do I handle replay and backfill?

Replay and backfill are how you fill a gap after the fact, and they work differently for each model.

Backfill with polling is the model itself. Ask for a date range, page through the results, and you have every event in that window. The same code you use day to day also loads history.

Replay with webhooks means re-sending past deliveries. With Datahyena you can replay a delivery from the dashboard, which covers a short blip. For a wide gap, fall back to a poll over the range, since replaying thousands of deliveries one by one is the slow path.

This is the clearest reason teams run both. Webhooks handle the live stream, and a date-range poll handles history and recovery in one query.

## Webhooks vs polling: the decision table

Here is the trade-off side by side. Read down the column that matches what you are building.

| Factor | Webhooks (push) | Polling (pull) |
| --- | --- | --- |
| Latency | Fires within moments of the event landing | Only as fresh as your interval |
| Reliability | Retried with backoff; replay from the dashboard; a long outage needs a backfill | Self-healing from a saved cursor; a failed run recovers on the next one |
| Complexity | You host, secure, and keep an endpoint online | One scheduled job calling an endpoint |
| Replay and backfill | Replay short gaps; poll a date range for wide ones | A date-range query is the native backfill |
| Wasted calls | None; you only hear about real events | Most calls return nothing new |
| Best fit | Low-latency reaction to new events | Periodic syncs and loading history |

No row makes one model strictly better. Webhooks trade operational work for speed. Polling trades freshness for simplicity.

## Which should I use for funding events?

Use webhooks when reacting fast is the point, polling when a periodic sync is enough, and both when you want speed and a safety net.

**Use webhooks** when an event should trigger an action right away: routing a newly funded company to a rep, firing an outreach sequence, or updating a live dashboard. You react in moments instead of waiting for the next poll. The same payload matches the record you would get from the API, so your handler stays simple.

**Use polling** when a regular refresh is fine and you would rather not run an endpoint. A nightly job that pulls the day’s funding rounds into your CRM is a clean fit. It is also the right tool for the first load of historical data and for backfills.

**Use both** when you want low latency and full coverage. Let webhooks drive real-time reaction, and run a periodic poll over a recent date range to catch anything a delivery missed. This is the setup most production teams land on, and it is why the [funding data API guide](https://datahyena.com/blog/funding-data-api-guide?utm_source=marketing&utm_medium=blog&utm_campaign=webhooks-vs-polling-for-funding-events) treats push and pull as two reads of the same clean record rather than rival products.

One rule holds across both: dedupe on the event id. Polling can hand you an event you already saw near a boundary, and at-least-once webhook delivery can repeat one on a retry. A stable id on every record makes that a non-issue.

## Start with one live funding event

The fastest way to choose is to see the record both models deliver.

When you are ready to wire up push delivery, the [webhooks page](https://datahyena.com/webhooks?utm_source=marketing&utm_medium=blog&utm_campaign=webhooks-vs-polling-for-funding-events) shows the events, signatures, and retries in full.

## Frequently asked questions

 What is the difference between webhooks and polling? With polling, your code asks the API for new funding events on a schedule. With webhooks, the API sends each new event to your endpoint the moment it lands. Polling is pull, webhooks are push.
 Are webhooks faster than polling for funding events? Yes. A webhook fires within moments of an event being ready, while polling is only as fresh as your interval. If you poll every hour, an event can sit unseen for almost an hour before your next call picks it up.
 How do I handle a missed funding event webhook? Pick an endpoint that retries failed deliveries and lets you replay past deliveries once your service is healthy. For longer gaps, run a periodic poll over a date range to backfill anything you missed.
 Should I use both webhooks and polling? Often, yes. Webhooks give you low-latency reaction to new events, and a periodic poll over a date range covers backfills and acts as a safety net for any delivery your endpoint missed.
