To access API.1 (Consent API and Accounting API), you must create an API Key. You create and manage API Keys in the Client Portal per environment.
Pass the key in requests
When you call API.1, pass your API Key in every request using the x-api-key HTTP header:
x-api-key: YOUR_API_KEY_HERE
Replace YOUR_API_KEY_HERE with the key you created in the Client Portal. Use a Development key for Development consents and sandbox data (e.g. Test.1); use a Production key for Production consents and live data from Your Customer's Accounting Systems.
For full request conventions, correlation IDs, and authentication, see Get Started.
