FAQ
These FAQs are a self-serve support resource for the GoldRush API.
Base URL
The API Host for all requests is https://api.covalenthq.com/v1
. Some additional points to keep in mind:
- All requests are done over HTTPS (calls over plain HTTP will fail.)
- The default return format for all endpoints is JSON unless the query parameter
format=csv
is specified. - All requests require authentication.
Authentication
To access the GoldRush API, you will need an API key. Various authentication mechanisms are available:
Authentication via Query parameter
curl -X GET https://api.covalenthq.com/v1/ENDPOINT/?key=API_KEY
Append key=API_KEY
as a query parameter to all requests.
Authentication via Basic Auth
curl -X GET https://api.covalenthq.com/v1/ENDPOINT/ \ -u API_KEY: -H 'Content-Type: application/json' # The colon prevents curl from asking for a password.
Provide your API key as the basic auth username. You do not need to provide a password.
