Request body

chainIdinteger

Numeric chain ID (e.g. 11155111 for Sepolia, 8453 for Base). On chain-aware trigger/node configs this is required and must be a configured chain; on query/filter params it is optional.

inputVariablesInputVariables required

Free-form key-value bag of values used to resolve {{variable.path}} template references inside trigger and node configs. Conventional well-known keys: settings.runner (smart wallet address), settings.chainId (chain id). camelCase keys; back-compat support for snake_case keys exists during the migration window.
