An API key is like a login/password that other software applications can use to interact with your Simplero account on your behalf.
Be careful who you give them to, as they're just like giving people admin rights to your account.
Create a new API key for each situation, so that you can easily delete ones that are no longer needed.
Adding an API Key
1. Go to Settings--> Integrations--> and the first section is called API Key
2. Select the blue button in upper right hand corner to create a new API key
3. Follow the pop up screens to add the API key. First you will give the API key a name
4. Once the system generates the API you will select the clipboard icon next to it, that will copy the API key to your dashboard and now you can paste it where you need it.
