# How to Call HTTP endpoint with SMS

Using [Flow Builder](https://dashboard.messagebird.com/en/flow-builder), you can easily trigger a GET or POST request for your own server when your flow receives an incoming SMS. Go to Flow Builder in the Dashboard, and create a new flow or use the template ‘Call HTTP endpoint with SMS’.

1. Select the phone number you’d like to attach flow to.
2. Click on the ‘Forward to URL’ Step, and set up the attributes. In ‘Method’ choose between GET or POST request; you also need to type down the URL of your webhook. Click on save when ready.
3. When you are done building your flow, click on either ‘Save draft’ or ‘Publish’ on the right top of the screen.
