Authentication

Create payment (POST /checkout/create/) and Get payment by id (GET /transactions/<id>/) require authentication. Use your organization API key.

API key​

Create and rotate your organization API key in the dashboard: Organization → API & Webhooks.

Send the key in the request header:

Authorization: Api-Key <your_api_key>

or:

Api-Key: <your_api_key>

Scopes​

The API key must have the checkout:create scope to call POST /checkout/create/. Default keys created from the dashboard include this scope.

curl -X POST "https://api.sandbox.nd8.com/api/checkout/create/" \
  -H "Authorization: Api-Key YOUR_API_KEY" \
