Hello everyone, does anyone have example of calling estimateExternalMessageFee method? i dont really understand what i should pass in initCode and initData fields

If you aren't initializing contract, likely null.

dont really understand how its works:

body: beginCell().storeUint(653058771, 32).storeUint(111n, 32).storeUint(0,32).endCell()

calculated: 0.000083852

body: beginCell().storeUint(653058771, 32).storeUint(111n, 8).storeUint(0,8).endCell()

calculated: 0.000083852

Why does it costs the same amount of money, if i am writing different amount of data?

Moreover, when i am really calling this method on-chain, it takes much more gas to pay

Do you call it by internal message? If so, you need to estimate fees in different way — likely with sandbox.

like just running tests in sandbox and watching the amount of ton i spent?

but what will happend if gasprice will be bigger?

just trying like that, is that means internal msg?

sandbox can use actual configuration values.

Yep, thanks just checking in sandbox and it's basically almost the same value as it's required in mainnet. TY ❤️

How do you send the message to the contract when not-testing?

using wrapper from generated tact code and tonConnect. basically we didn't know how much value we need to send, so we we're trying to use almost any value. now i know how much i need to send, but for safe purposes i'll send a bit more. like 0.001 TON more than i get from tests
