In a extremely interconnected on-line area, programs and purposes should have the means to speak effectively. In any other case, for the reason that internet’s infrastructure is constructed with connectivity as a central attribute, programs wouldn’t be capable to function optimally. That is the place webhooks come into the equation since they current one of the vital environment friendly methods in how programs talk.
Nonetheless, webhooks are HTTP requests despatched to a vacation spot system (receiver) based mostly on particular occasions triggered in a supply system (sender). Consequently, the supply system notifies the vacation spot system when a specific occasion happens. Furthermore, together with a notification, webhooks typically embody ”request payloads” containing further data concerning the occasions.
Now, with a short understanding of webhooks and why they’re useful, allow us to have a look at what they entail within the context of Web3!
Web3 Webhooks
Web3 webhooks serve the identical goal as typical webhooks: to allow cross-system communication. Nonetheless, since Web3 is predicated on blockchain infrastructure and runs on sensible contracts, there are some elementary variations between the 2. As such, blockchain builders use Web3 webhooks to take heed to blockchain occasions. This may be every little thing from pockets transactions to extra advanced sensible contact occasions.
Moreover, builders use Web3 webhooks to keep away from redundant duties like constantly checking the state of a blockchain or polling databases. As an alternative, they will arrange webhooks for sensible contract occasions that curiosity them to mechanically obtain request payloads once they set off. That is considerably extra environment friendly, permitting blockchain builders to avoid wasting assets and time.
So, if you happen to have been to arrange a Polygon webhook, the blockchain (supply system) would ship knowledge to your specified webhook URL based mostly on the sensible contract occasions that curiosity you. For instance, you should utilize Polygon webhooks to watch transfers of a certain quantity on the blockchain. On this case, you’d obtain a Polygon webhook at any time when a switch exceeds, let’s say, $100,000 on-chain!

const stream = {
chains: [EvmChain.ETHEREUM, EvmChain.POLYGON], // Listing of blockchains to watch
description: “monitor Bobs pockets”, // Your description
tag: “bob”, // give it a tag
webhookUrl: “https://YOUR_WEBHOOK_URL”, // Webhook URL to obtain occasions,
}
From there, use the ”stream” object to name Moralis’ ”Moralis.Streams.add(stream)” perform. Lastly, create a brand new ”{ id }” object and add the pockets handle that you just wish to monitor:
const newStream = await Moralis.Streams.add(stream);
const { id } = newStream.toJSON(); // { id: ‘YOUR_STREAM_ID’, …newStream }
// Now we connect Bobs handle to the stream
const handle = “0x68b3f12d6e8d85a8d3dbbc15bba9dc5103b888a4”;
await Moralis.Streams.addAddress({ handle, id });

chains: [EvmChain.ETHEREUM, EvmChain.POLYGON], // Listing of blockchains to watch
description: “monitor Bobs pockets”, // your description
tag: “bob”, // give it a tag
webhookUrl: “https://YOUR_WEBHOOK_URL”, // Webhook URL to obtain occasions,
}
const newStream = await Moralis.Streams.add(stream);
const { id } = newStream.toJSON(); // { id: ‘YOUR_STREAM_ID’, …newStream }
// Now we connect bobs handle to the stream
const handle = “0x68b3f12d6e8d85a8d3dbbc15bba9dc5103b888a4”;
await Moralis.Streams.addAddress({ handle, id });
