You need to be a Next Matter administrator to create an API key.

To generate the key:

2. Go to **Company > Next Matter API keys**.
3. Click **+ Create API key**.

Authenticate by passing the API key in the "Authorization"
HTTP header proceeded with the string "Api-Key ".

For example:

Authorization: `Api-Key xyzabc.12fsfe242ubdgakew`
