The API can be accessed by creating a Personal Access Token in the Parallax application.
Personal Access Tokens, once generated, will need to be copied and saved somewhere safe. You will not be able to see the Personal Access Token again after generating. In the event you forget to copy/lose the token, you'll need to create a new one.
Once generated, Personal Access Tokens can be sent in the X-API-KEY header. Each request will require the Personal Access Token to access the API.
We had formerly documented Authorization: Bearer here, but we will reserve that for future use with OAuth/JWTs. Please use the X-API-KEY header for Personal Access Tokens.
