# How to setup an alert ?

Tenderly allows to monitor contracts and send alert when a specific function is called or an event emitted.

**Step 1:** Go the the alert page


**Step 2:** Click on new Alert


**Step 3:** Select the type of alert, in our example it will be an alert on a function call.


**Step 4:** Select the contract and the function. In our example we will monitor the vesting contract and its updateMerkleRoot function.


**Step 5:** Select where you want to be notified, I selected telegram. And then click on save.



Congrats ! you configured your first alert ! from now on you will receive a message on telegram when the merkle root is updated. :heavy_check_mark:
