# getId/setId

How to use getID and setID to create transactions

## **What’s the use of getId and setId?**

**setId** and **getId** can be used to input data correctly across spells. Values stored in specific IDs can be stored in one spell and used in another spell. 

### **Example of using  getId and setId**

> Let’s say I want to sell USDC to buy ETH on 1Inch and then deposit bought ETH into Compound.

1. So I sell USDC on 1Inch, and I store the bought ETH amount at `setId` (let’s say it’s `482` as setId for now) on `sell()` function of 1inch.
2. Then I will use `482` as getId on compound deposit() function and deposit the bought ETH in Compound. In deposit function, I don’t need to mention the amount specifically to deposit. It will get the deposit amount from `getId` that is passed.

### **Code Snippet:**

```
spells.add({
  connector: "oneInch",
  method: "sell",
  args: [eth_address, usdc_address, sellAmount, unitAmt, 0, "482"] // setting bought ETH amount at id 482
});

spells.add({
  connector: "compound",
  method: "deposit",
  args: [eth_address, 0, "482", 0] // getting deposit amount from id 482
});
```

**Note:**

1. For `getId`, if the id is `0` then it won’t get the stored amount but it will use the amount that’s passed in the function.
2. For `setId`, if the id is `0` then it won’t stored amount.
