The SDK is suitable when you need to integrate task creation into your development environment or automated scripts. It’s also useful for complex setups that require conditional logic before task submission. Use the automate-sdk to easily create a new task: 
yarn install @gelatonetwork/automate-sdk
Typescript Functions are still in private beta, make sure to use the beta version of the automate-sdk to have access to it

​
Typescript Function

Import the sdk and create task, passing your typescript function CID & arguments: 
import { AutomateSDK, Web3Function } from "@gelatonetwork/automate-sdk";

const automate = new AutomateSDK(chainId, deployer);

const { taskId, tx } = await automate.createBatchExecTask({
  name: "Web3Function - Eth Oracle",
  web3FunctionHash: cid,
  web3FunctionArgs: {
    oracle: oracle.address,
    currency: "ethereum",
  },
  trigger: {
    // Run every minutes
    type: TriggerType.TIME,
    interval: 60 * 1000,
  },
});
await tx.wait();
You can specify cron trigger this way: 
trigger: {
  type: TriggerType.CRON,
  cron: "0 8 * * *", // Run every day at 8:00
}
event trigger like this: 
trigger: {
  type: TriggerType.EVENT,
  filter: {
    // Listen to PriceUpdated event on Oracle contract
    address: oracle.address,
    topics: [[oracle.getEventTopic("PriceUpdated")]],
  },
  blockConfirmations: 0, // Trigger immediately
},
And block trigger this way: 
trigger: {
  type: TriggerType.BLOCK,
}
If your task utilizes secrets, you can set them after the task has been created. 
const web3Function = new Web3Function(chainId, deployer);

const secrets = {
  API_KEY: "..." // Set your secret environment variables
}
await web3Function.secrets.set(secrts, taskId);

​
Solidity Function

Repeat the installation step as shown above, then import and instantiate the SDK: 
const automate = new AutomateSDK(chainId, signer);
Use createTask to automate your function calls: 
interface CreateTaskOptions {
  name: string;             // your task name

  // Function to execute
  execAddress: string;      // address of your target smart contract
  execSelector: string;     // function selector to execute on your target smart contract
  execAbi?: string;         // ABI of your target smart contract

  // Proxy caller
  dedicatedMsgSender: boolean;  // task will be called via a dedicated msg.sender which you can whitelist (recommended: true)

  // Optional: Pre-defined / static target smart contract inputs
  execData?: string;        // exec call data 
  
  // Optional: Dynamic target smart contract inputs (using a resolver)
  resolverAddress?: string; // resolver contract address
  resolverData?: string;    // resolver call data (encoded data with function selector)
  resolverAbi?: string;     // your resolver contract ABI

  // Optional: Time based task params
  interval?: number;        // execution interval in seconds
  startTime?: number;       // start timestamp in seconds or 0 to start immediately (default: 0)
  
  // Optional: Single execution task
  singleExec?: boolean;     // task cancels itself after 1 execution if true.
  
  // Optional: Payment params
  useTreasury?: boolean;    // use false if your task is self-paying (default: true)
}

const params: CreateTaskOptions = {
  name,
  execAddress,
  execSelector,
  interval
};

const { taskId, tx }: TaskTransaction = await automate.createTask(params);

​
Examples

​
Deploy a contract & automate your function call:

// Deploying Counter contract
const counterFactory = await hre.ethers.getContractFactory("Counter");
const counter = await counterFactory.deploy(GELATO_ADDRESSES[chainId].automate);
await counter.deployed();

// Call Counter.increaseCount(42) every 10 minutes
const  { taskId, tx }: TaskTransaction = await automate.createTask({
  execAddress: counter.address,
  execSelector: counter.interface.getSighash("increaseCount(uint256)"),
  execData: counter.interface.encodeFunctionData("increaseCount", [42]),
  execAbi: counter.interface.format("json") as string,
  interval: 10 * 60, // execute every 10 minutes
  name: "Automated counter every 10min",
  dedicatedMsgSender: true
});​

​
Use a Checker to automate your function call:

If you need more configurable execution condition and/or dynamic input data, you can create a task using Checker 
// Prepare Task data to automate
const counter = new Contract(COUNTER_ADDRESSES, counterAbi, signer);
const resolver = new Contract(COUNTER_RESOLVER_ADDRESSES, counterResolverAbi, signer);
const selector = counter.interface.getSighash("increaseCount(uint256)");
const resolverData = resolver.interface.getSighash("checker()");

// Create task
const { taskId, tx }: TaskTransaction = await automate.createTask({
  execAddress: counter.address,
  execSelector: selector,
  resolverAddress: resolver.address,
  resolverData: resolverData,
  name: "Automated counter using resolver",
  dedicatedMsgSender: true
});

​
Automated Transaction

The CreateTaskOptions interface is used for configuring Automated Transactions with the same structure and options as defined above. The only difference is you need to configure your automated transaction without the need for a checker function. Example: 
interface CreateTaskOptions {
  name: string; // Name your task
  execAddress: string; // Address of your target smart contract
  execSelector: string; // Function selector to call on your target smart contract
  execAbi?: string; // ABI of your target smart contract (optional)
  execData?: string; // Call data for the function execution (optional)
}

​
Single Execution Task

If you want to have Gelato call your function only once. If so, set singleExec flag to true when calling createTask. 
const { taskId, tx }: TaskTransaction = await automate.createTask({
  execAddress: counter.address,
  execSelector: selector,
  resolverAddress: counter.address,
  resolverData: resolverData,
  dedicatedMsgSender: true,
  name: "Automated counter using resolver",
  dedicatedMsgSender: true,
  singleExec: true
});
