Get your Higgsfield API key
Find your Higgsfield Key ID and Key Secret.
A Higgsfield key comes in two halves, and Monk needs both. The Key ID is the public half that says which account is calling. The Key Secret is the private half, and Higgsfield shows it only once.
They are two different values. Pasting the Key ID into both fields will not work.
Using Higgsfield Marketing Studio? That connects a different way, a one time login instead of an API key. See Connect Higgsfield.
How to get them
- Go to cloud.higgsfield.ai/api-keys and log in.
- Click Create API key.
- Higgsfield shows a Key ID and a Key Secret.
- Copy the Key ID and paste it into Monk.
- Copy the Key Secret and paste it into Monk.
Copy the secret before you leave that screen. Higgsfield never shows it again. If you lost it, create a new key.
Is it safe?
Yes. Both halves are encrypted at rest and used only to generate your ads. They are never shared or shown in full.
