# Removing liquidity

To remove the liquidity from a pool, the user needs to provide LP tokens.

### Step 1: **Check the allowance of the pool contract on both tokens.**

To initiate a swap, first determine if the DEX has the necessary allowance to access the tokens. This can be done using the following API endpoint: 

**API URL**: [`https://api.expand.network/fungibletoken/getuserallowance`](https://docs.expand.network/how-to/provision-liquidity/https:/api.expand.network/fungibletoken/getuserallowance)

***

**Sample Request:**

```url
https://api.expand.network/fungibletoken/getuserallowance?owner=0x6Fb447Ae94F5180254D436A693907a1f57696900&tokenAddress=0x6b175474e89094c44da98b954eedeac495271d0f&spender=0xBA12222222228d8Ba445958a75a0704d566BF2C8
```

***

**Sample Response:** 

```json
{
    "status": 200,
    "msg": "success",
    "data": {
        "allowance": "999000000000000000000"
    }
}
```

### Step 2: **Approve the pool contract from the tokens**

This can be done using the following API endpoint: 

**API URL**: [`https://api.expand.network/fungibletoken/approve`](https://docs.expand.network/categories/fungible-tokens/erc20#approve)

***

**Sample Request:**

```json
{
    "from": "0x63056E00436Da25BcF48A40dfBbDcc7089351006", 
    "tokenAddress":"0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",  
    "amount": "1000000000000000000000",                  
    "to": "0x828b154032950c8ff7cf8085d841723db2696056", 
    "gas": "100000",
    "chainId": "1"
}
```

**Sample Response:** 

```json

    "status": 200,
    "msg": "success",
    "data": {
        "from": "0x63056E00436Da25BcF48A40dfBbDcc7089351006",

    }
}
```
