> Edit: This information has changed and is now found in our [Sensor Indexes and Read Keys](https://community.purpleair.com/t/sensor-indexes-and-read-keys/4000) community article.

A registration confirmation email is sent after successfully registering a device. This email will allow you to obtain the read key for your sensor. You’ll want to look at the bottom of the email for a section labeled “Useful Links,” and the link labeled “View on the PurpleAir map.”

The link might look something like this: `https://www.purpleair.com/map?zoom=4&lat=40&lng=-110&key=NY8JP6D1SB73V78G`

The sensor’s read key is after “key=” meaning that it would be “NY8JP6D1SB73V78G” in this case.

Additional information on using a sensor’s read key in an API call is found in our [Making API Calls with the PurpleAir API](https://community.purpleair.com/t/making-api-calls-with-the-purpleair-api/180#get-sensor-data-request-10) article.
