cg.coin.info.updated - CoinGecko API

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
`data.changes[].change_type`	`addition`, `update`, or `removal`
`data.changes[].new_value`	Updated value. `null` if removal.
`data.changes[].old_value`	Previous value. `null` if addition.
