Bitcoin webhook API for transaction and address notifications

A Bitcoin webhook API tells your app the moment something happens on-chain instead of making you poll for it. Watch an address and get a callback when it receives a payment, when a transaction it sent gets its first confirmation, or when it reaches the confirmation depth you require. BitcoinDatabase tracks the chain tip block by block and posts a JSON payload to your endpoint within seconds of the event, so payment flows, deposit crediting and monitoring dashboards react in real time.

You register the addresses or transaction IDs you care about, set the confirmation threshold that matters for your risk model, and we handle the rest: retries on failure, signed payloads you can verify, and the same event history queryable over REST if you miss one. No node to run, no mempool to watch yourself. This is informational on-chain data only, not financial or investment advice.

Why it works

What you get with webhook api

Events, not polling

Register an address or transaction and receive a callback the instant it sees activity or reaches your confirmation threshold, so you stop hammering an endpoint on a timer.

Confirmation-aware

Fire at zero-conf for fast UX or wait for the depth your risk model needs. You choose the threshold per subscription, from mempool sighting to six confirmations.

Reliable delivery

Payloads are signed so you can verify them, delivery retries on failure, and every event stays queryable over REST so a missed webhook is never lost data.

What it handles

The indexed Bitcoin chain, queryable your way

Look up an address, a transaction, a UTXO, the rich list or an on-chain metric, by REST API, SQL or dashboard. The same authoritative data, reconciled block-by-block against the canonical chain, without running a node.

Get notified when a watched address receives BTC
Trigger on first confirmation or a custom depth
Credit deposits and reconcile payments automatically
Verify signed payloads and replay missed events over REST
Monitor thousands of addresses without running a node

Why BitcoinDatabase

One platform, queryable three ways

Not a raw node to sync, not an indexer to build, and not five vendors to stitch together. The fully-indexed Bitcoin blockchain, available as a REST API, as SQL, and as dashboards, on one authoritative dataset.

REST API

Typed JSON for addresses, transactions, balances, UTXOs and metrics. Drop it into apps, wallets, explorers and agents with curl, Python or our SDKs.

SQL access

Run SQL directly against the indexed Bitcoin dataset for ad-hoc analysis, cohorts and exports, the same data the API and dashboards read from.

Compliance-first

Informational on-chain data and analytics only. Entity labels and flow tracing are framed as tooling to support a regulated team's own review, not accusations.

Good questions

Questions about webhook api

We track the chain tip block by block, so a callback typically reaches your endpoint within seconds of the triggering event, whether that is a mempool sighting or a confirmation at the depth you set. Delivery retries on failure and every event stays queryable over REST as a backstop.

Yes. You can subscribe thousands of addresses and transaction IDs to webhooks and set a confirmation threshold per subscription. That is common for exchanges and payment processors crediting deposits. This is informational on-chain data only, not financial advice.
