Get ABI code for an ethereum contract event

Question

How can I construct the ABI code for a contract event?

I don't need the whole contract ABI.

Example:

• transferFrom(address,address,uint256)
• executeMetaTransaction(address,bytes,bytes32,bytes32,uint8)

I need to get the ABI code for events like this.

Should I just create a basic contract with the event in Remix and compile it?

You can get the whole ABI via Etherscan API and then via for loop filter out only the event related part.

Here is a snippet from a Python code on how to do it:

# contract ABI extraction via Etherscan API
events = []
etherscan_url = f'https://api-goerli.etherscan.io/api?module=contract&action=getabi&address={contract_address}&apikey={etherscan_api}'
etherscan_response = requests.get(etherscan_url)
etherscan_content = etherscan_response.json()
contract_abi = etherscan_content.get("result")
contract_abi_dict = json.loads(contract_abi)
print(f"ABI: {contract_abi}")

# Event name extraction
for i, j in enumerate(contract_abi_dict):
    if contract_abi_dict[i]['type'] == "event":
        events.append(contract_abi_dict[i]['name'])
        print(contract_abi_dict[i]['name'])
