Hi there!
Both the API Key and Dev ID are located in the top right corner under "API keys".
Regarding the Terra_Secret (signing secret):
The signing secret is not required for API initialization - it's specifically used for webhook verification. You can find your webhook secret on Dashboard > Connections > Webhook and copy the signing secret .
So to clarify:
- Required for API calls: API Key and Dev ID
- Optional for webhook verification: Signing Secret
