I think you're looking for pancakeswap router docs , play around on this. Also, you can utilize pancakeswap testnet.

Using the Pancake router V2 you can swap tokens, look into

https://docs.pancakeswap.finance/code/smart-contracts/pancakeswap-exchange/router-v2#swapexacttokensfortokens

Here is the function you would need to call for swapping two tokens which you could call in your smart contract

        function swapTokensForExactTokens(
    uint amountOut,
    uint amountInMax,
    address[] calldata path,
    address to,
    uint deadline
    ) external virtual override ensure(deadline) returns (uint[] memory amounts) {}
