# Populate a step with transaction data

> This endpoint expects a full `Step` object which usually is retrieved by calling the `/advanced/routes` endpoint and selecting the most suitable `Route`. Afterwards the transaction for every required `Step` can be retrieved using this endpoint.
**Attention**: This request is more complex and intended to be used via our [JavaScript SDK](https://docs.li.fi/integrate-li.fi-js-sdk/install-li.fi-sdk).

        An estimate of the network gas the sender pays for a transaction. Gas

            - `SEND`: estimated network gas for the transaction the sender
            submits, normally on the source chain. This is the only value the
            API currently returns.

            - `APPROVE`: estimated network gas for a separate ERC-20 approval
            transaction. Reserved; approval gas is not currently returned as its
            own entry.

            - `FEE`: an execution cost charged as a fee rather than as a
            transaction the user signs. Reserved; such costs are currently
            reported in `feeCosts` instead.

            - `SUM`: an aggregate of the other entries. Reserved and not
            currently returned.


            Treat `APPROVE`, `FEE`, and `SUM` as forward-compatible values:
            handle them if they appear, but do not build a flow that depends on
            them.
