[SOLVED] from_block, to_block, from_date, to_date are not working in getContractEvents?

I’m currently working on getting events using getContractEvents. However, I tried to use the filter for real-time monitoring, but I am having a hard time understanding the meaning of the parameters. Can someone give me the exact meaning and examples of the parameters pointed out above?

#2

When you are using from_block, to_block or from_date, to_date parameters, the response from the API response gets narrowed down to the events that are emitted between from_block, to_block or from_date, to_date.

#3

Yes… You are right. That’s what the documentation says too.
But when I tried, these parameters had no effect. Do I have to use pair parameters?

For example, to get all events from block 100001 I set from_block to 100001 and did not use to_block. But in getContractEvents(), it was getting from 100000. Why? what am I doing wrong…

#4

no, it is not compulsory to use both from and to.

Can you share the code or the other params which you are passing, so I can test it from my side.

Thanks.

I share with you my way.

The code:

const ABI = {
      anonymous: false,
      inputs: [
        { indexed: false, internalType: "uint256", name: "data", type: "uint256" }
      ],
      name: "blinkEvent",
      type: "event",
};
    
const options = {
      chain: "0x4",
      address: "0xE1Ca572A6eF730a689DD7410ac506db590b226e3",
      topic: "0x1cb6056beb959587a774ae7cd856a3569b7ca72caf1cff8cecba45b801a56e69",
      from_block: 11486221,
      abi: ABI,
};
const events = await Moralis.EvmApi.events.getContractEvents(options);

The Result: (Only what we need…)

Can you update param name to camelCase and try again. All the param names in sdk follows camelCase format.

fromBlock: 11486221,

It should return the expected results after updating.

Great!

It was resolved. That is, the camelCase format was the reason.
Thank you a lot
