"Error initializing BioDigital Human API [...] API functionality unavailable for this session"

If you see this error in the developer console when you are trying to load a model with the Human Viewer API, this means one of two things:

1. The developer key in your embed code is invalid, or
2. A developer key is missing from your embed code entirely.

You can learn more by looking at your embed code:

• If you don't see dk= followed by a string of letters and numbers, your code is missing a developer key. 
• If you do see dk= followed by a string of letters and numbers, it is likely your developer key is invalid.

In either case, you will need to add a valid developer key to your embed code. There are two ways to do this:

• Re-publish the model from your My Library to retrieve a new embed code.

  • If your user account is associated with a developer account (i.e., you have registered an app), this will insert a developer key into your embed code.
  • If your user account is not associated with a developer account, this will insert a uaid into your embed code.
• Manually append your or your team's developer key to the URL in your embed code (preceded by "&").
