What are NFT marketplace alerts?
NFT marketplace alerts are notifications that are sent to users when there is activity related to non-fungible tokens (NFTs) on a particular NFT marketplace. These alerts can be in the form of email notifications, mobile app notifications, or browser notifications.
NFTs are unique digital assets that have become incredibly popular. People can buy, sell, and trade NFTs on various NFT marketplaces. However, with so much activity happening on these platforms, staying up-to-date with all the new listings, bids, and sales can be hard.
To stay updated with all new listings, you can set up alerts on these marketplaces. These alerts will notify you in real time of the important marketplace events that you’ve indicated you care about.
Common Types of NFT Marketplace Alerts
Various types of alerts can be set up for NFT marketplaces, including:
1. NFT Price Changes
Price change alerts can be beneficial for monitoring the value of your NFT collection or finding opportunities to buy low and sell high. Price change alerts notify you whenever the price of NFT changes.
2. NFT Sales
Sale alerts let you know when an NFT has been sold. This can be helpful if you want to keep track of NFT prices or if you want to buy or sell NFTs based on recent sales.
3. NFT Bids and Offers
Bid and offer alerts keep you updated whenever someone places a bid or offer on an NFT you're interested in. Bid and offer alerts are handy when you're trying to buy or sell an NFT and want to stay informed about the latest activity.
4. New NFT Listings
New listing alerts inform you whenever a new NFT is added to the marketplace. New listing alerts are helpful if you're looking to collect a specific type of NFT or if you want to keep up-to-date with new releases from your favorite creators.
What are the benefits of using Custom Webhooks for NFT marketplace alerts?
Custom Webhooks are a useful tool for getting real-time alerts from NFT marketplaces. Some benefits of using Custom Webhooks for real-time NFT marketplace alerts are:

How are Custom Webhooks used for tracking NFT Marketplace Alerts?
While it is possible to utilize built-in NFT marketplace alerts to track changes, this approach can be limiting in terms of the data that users can obtain. As a result, many users may find it necessary to explore alternative methods for obtaining the information they require.
Custom Webhooks for NFT marketplace alerts are a powerful tool that allows users to receive real-time notifications when NFTs on a marketplace are updated or changed.

How to Use Alchemy’s Custom Webhooks for NFT Marketplace Alerts
Alchemy's Custom Webhook allows developers to stream on-chain data and get immediately notified about the most recent blockchain data changes. Custom Webhooks utilize a GraphQL interface so that web3 developers can have rich filters and only receive the precise blockchain data they need.
Step 1: Sign up for Alchemy
To start with Alchemy’s Custom Webhooks, visit the Alchemy website and create an account. This will give you access to the Alchemy Dashboard, which is your starting point.
Step 2: Choose the NFT Marketplace
Once you have access to the Alchemy Dashboard, the next step is to select the NFT marketplace you want to monitor. Various NFT marketplaces are available, such as OpenSea, Rarible, SuperRare, and others.
Step 3: Set Up the NFT Monitoring Webhook
Once you have chosen the NFT marketplace of your choice, the next step is to set up the webhook. To do this, you can navigate to the [Notify tab on the Alchemy Dashboard](https://www.alchemy.com/notify).
This tab allows you to configure a webhook to receive real-time alerts about blockchain events, including events related to NFT marketplaces.
To proceed, locate and select the "Create Webhook" button found under GraphQL. Once selected, you will be prompted to provide various inputs, including the Chain, Network, and Webhook URL, as shown in the following step.
Step 4: Test the NFT Marketplace Webhook
Choose the appropriate chain, network, and webhook URL to specify where your requests or alerts will be posted. For this example, the Ethereum Mainnet is being used.
Next, focus your attention on the address field.
Within this field, you will need to input the contract address of the collection you wish to track.
To obtain the contract address, begin by selecting your preferred marketplace. In this example, we will be using OpenSea.
Once selected, navigate to the OpenSea marketplace and choose any of the available collections, as depicted in the accompanying image below.
Next, select the Etherscan icon as depicted below.
Doing so will open a new page containing various details related to the collection, such as the contract address, ETH balance, transaction hash, and other pertinent information.
Copy the collection contract address.
Having copied the collection address, proceed to paste it into the designated address field, as illustrated below.
To specify the webhook URL, we will be utilizing the webhook.site.
Begin by signing up for an account on the website to obtain a unique URL that can be utilized as the webhook URL. This will enable you to receive all necessary updates related to any transactions or alerts.
Retrieve the unique URL provided by the webhook.site and proceed to paste it into the designated webhook URL field.
Once all necessary steps have been completed, select the "Test Webhook" button to ensure proper functionality. Afterward, navigate to the webhook.site to view the corresponding post requests.
Below is an example of a post request, which includes relevant details such as webhookId, id, transaction hash, and more.
Step 5: Deploy the Webhook
If testing works fine, proceed to click the "Create Webhook" button to activate the webhook. Upon doing so, navigate to the webhook.site and observe any relevant requests that are generated when NFT transactions occur.
As illustrated below, the status should indicate that the webhook is currently active, thereby enabling you to receive up-to-date information related to any NFT transactions.
You can see that there are multiple post requests for the transaction.
If the tracking of a particular collection is no longer desired, there are several options available. One option is to deactivate the tracking, while another option is to delete the tracking entirely.
