# stx\_callContract

You can use the `stx_callContract` method to request the signature of any contract call transaction from the user's wallet. The method lets you specify the contract to call, the function to execute on the contract and the arguments to pass to the function.

```typescript
    import { request } from "sats-connect";

      const response = await request("stx_callContract", {
        contract: `${contractAddress}.${contractName}`,
        functionName,
        functionArgs: JSON.parse(functionArgs),
      });
      if (response.status === "success") {
        console.log(response.result);
      } else {
        console.error(response.error);
      }
    } catch (error) {
      console.error(error);
      alert(error);
    }
```

The user will see a Stacks contract call transaction signing request prompt in the wallet.&#x20;

The transaction will be signed and broadcasted upon user approval.

The `stx_callContract` method returns a Promise that resolves to the `CallContractResult` object:
