Correlate the instructions of the innerInstructions

Question

I get the parsed transaction from Solana (getParsedTransaction) and I would like to specifically parse the instructions and their corresponding innerInstructions. How can I know that my innerInstruction[0] belongs to this or that instruction? Directly from the transaction, without any new RPC request. I can't find any index or simple information telling me that the innerInstruction is linked to such and such instruction. I hope I am clear in my question!

Thank you!

Answer 1

ParsedInnerInstruction.index should correspond to the index of the outer instruction that houses the inner instruction.

So if parsedTransaction.meta.innerInstructions[0].index is say 1, then it means the outer instruction is parsedTransaction.transaction.message.instructions[1] is the parent.
