API Integration
How to find my key
You can view and manage your API keys on your Willo Integrations page by selecting Developer tools.
Authentication
Each user has their own API key. This API key carries the same permissions as this user and will dictate the permissions of any requests made using this API key.
All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
Cycle your API key at any time - important if you think someone else has obtained it without your permission. Issue new key.
Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code etc.
