What are Webhooks, and How Do They Examine to Web3 Webhooks?
Earlier than taking a more in-depth have a look at Web3 webhooks, this preliminary half delves deeper into the intricacies of typical webhooks. Accordingly, we are going to start this Polygon webhooks tutorial by answering the query, ”what are webhooks?”.
In a extremely interconnected on-line area, methods 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, methods wouldn’t have the ability to function optimally. That is the place webhooks come into the equation since they current probably the most environment friendly methods in how methods talk.
However, 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 selected occasion happens. Furthermore, together with a notification, webhooks usually embody ”request payloads” containing further data relating to the occasions.
Now, with a quick 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 objective as typical webhooks: to allow cross-system communication. Nonetheless, since Web3 relies on blockchain infrastructure and runs on good contracts, there are some basic variations between the 2. As such, blockchain builders use Web3 webhooks to take heed to blockchain occasions. This may be every part from pockets transactions to extra complicated good contact occasions.
Moreover, builders use Web3 webhooks to keep away from redundant duties like repeatedly checking the state of a blockchain or polling databases. As a substitute, they will arrange webhooks for good contract occasions that curiosity them to routinely obtain request payloads after they set off. That is considerably extra environment friendly, permitting blockchain builders to avoid wasting assets and time.
So, for those who have been to arrange a Polygon webhook, the blockchain (supply system) would ship information to your specified webhook URL based mostly on the good contract occasions that curiosity you. For instance, you need to use Polygon webhooks to observe transfers of a certain quantity on the blockchain. On this case, you’d obtain a Polygon webhook each time a switch exceeds, let’s say, $100,000 on-chain!
Consequently, as you may think about, it’s extremely helpful for builders to have the ability to arrange Web3 webhooks simply, and probably the most accessible method to take action is by organising Web3 streams with Moralis’ Streams API. If this sounds fascinating, be a part of us as we present you how you can create Polygon webhooks with related performance as the instance above!

Subsequent up, create a brand new object referred to as ”stream” and add the next properties: the chain(s), an outline, a tag, and a webhook URL. Under, one can find an instance of what it ought to appear to be:
const stream = {
chains: [EvmChain.ETHEREUM, EvmChain.POLYGON], // Checklist of blockchains to observe
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)” operate. Lastly, create a brand new ”{ id }” object and add the pockets tackle that you just need to monitor:
const newStream = await Moralis.Streams.add(stream);
const { id } = newStream.toJSON(); // { id: ‘YOUR_STREAM_ID’, …newStream }
// Now we connect Bobs tackle to the stream
const tackle = “0x68b3f12d6e8d85a8d3dbbc15bba9dc5103b888a4”;
await Moralis.Streams.addAddress({ tackle, id });
Finally, your JavaScript file ought to now look one thing like this:
import Moralis from ‘moralis’;
import { EvmChain } from “@moralisweb3/evm-utils”;
Moralis.begin({
apiKey: ‘YOUR_API_KEY’,
});

chains: [EvmChain.ETHEREUM, EvmChain.POLYGON], // Checklist of blockchains to observe
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 tackle to the stream
const tackle = “0x68b3f12d6e8d85a8d3dbbc15bba9dc5103b888a4”;
await Moralis.Streams.addAddress({ tackle, id });
That covers the way you arrange a Polygon webhook programmatically with Moralis! All that is still is opening a terminal and working the code under with the file’s identify:
node “FILE_NAME”

Required Polygon Take a look at Webhooks
It doesn’t matter for those who create Polygon webhooks programmatically or by way of Moralis’ internet UI; you’ll all the time obtain a Polygon check webhook when launching a brand new stream. Consequently, to make the streams absolutely operational, you have to return standing code 200. You will discover the check physique down under:
{
“abi”: {},
“block”: {
“hash”: “”,
“quantity”: “”,
“timestamp”: “”
},
“txs”: [],
“txsInternal”: [],
“logs”: [],
“chainId”: “”,
“tag”: “”,
“streamId”: : “”,
