# Update config pool

`PATCH https://api.cryptohopper.com/v1/hopper/{id}/config/pool/{pool_id}`

Part of [Bot config](https://www.cryptohopper.com/api-documentation/api-reference/bot-config.md) in the Cryptohopper API reference.

Updates a config pool of the hopper. The config is validated before it is saved; name, coins and enabled are optional.

OAuth scope: `read`, `manage`

config is required. The field names differ from creating a pool: name and coins instead of pool_name and selected_coins. coins can be an array or a comma separated string; an empty value clears the coins. enabled accepts true, false, 1 or 0. Not available for AI Bots.

## Path parameters
