DALL-E API Key different than OpenAI Key?

I generated two different API keys in the OpenAI settings page. I am trying to use the key to make a call to DALL-E to generate and post an image. After many tries, the API still shows 0 activity and I’m getting no results from my script. Is the OpenAI key the same for DALL-E? The documentation is ambiguous.

Welcome.

The keys are the same. Are you getting an error in response?
