cg.coin.info.updated

Triggered when core coin information is updated on CoinGecko

Dispatched whenever a coin’s metadata, links, categories, contract addresses, or images change on CoinGecko.com.

Use Cases

Automated Asset Updates

Update your UI when a token rebrands, changes ticker, or updates its logo.

Cross-Chain Contract Monitoring

Detect when a project deploys on a new chain or migrates a contract address.

Risk & Compliance

Act on critical alerts — malicious activity warnings or contract migration notices.

Bots & Alert Systems

Notify your community when a project updates its whitepaper, GitHub repo, or social links.

Tracked Fields

The webhook listens for changes in the following fields. Each change is reported as an addition, update, or removal in the payload.

Field	Description	Example
id	CoinGecko coin ID. Typically immutable — only changes to fix errors.	bitcoin, usd-coin
symbol	Ticker symbol.	btc, usdc
name	Display name.	Bitcoin, USDC
web_slug	URL slug on CoinGecko.com. Can differ from id.	bitcoin, usdc
platforms.{asset_platform_id}	Token contract address on a given chain. See Asset Platforms List.	platforms.ethereum → 0x1f98...
categories	Category IDs assigned to the coin.	meme-token, artificial-intelligence
public_notices	Security breach info and contract migration announcements.	$MATIC was upgraded 1:1 to $POL...
additional_notices.{status}	Flags like can_mint_new_tokens or has_unverified_contract.	true, false, or null
links.{site}	Official websites and social media links.	links.homepage, links.whitepaper, links.twitter_screen_name
image	Image filename (not URL). Use /coins/{id} or /coins/markets to get full URLs.	uniswap-logo.png

When platforms.{asset_platform_id} changes its key (e.g. xdai → ethereum), two changes are sent: a removal of the old key and an addition of the new key.

For links.homepage, links.official_forum_url, links.chat_url, and links.announcement_url — only update events are triggered.

• The payload contains the full array of links.
• A removed link returns an empty value.

Payload

Each payload contains the event type, coin identity, and an array of changes describing exactly what was modified.

Field	Description
event_type	cg.coin.info.updated
data.id	CoinGecko coin ID
data.symbol	Coin symbol
data.name	Coin name
data.changes	Array of change objects
data.changes[].field	Field that changed
