Authentication
Send an API key as a bearer token. This endpoint does not state a specific permission in the specification, so give your key the least it needs and check the response rather than assuming.
Where your organisation id goes
This endpoint takes org_id as a query parameter. Leave it out and the call covers your whole tenancy subtree; send it to narrow the call to one organisation.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X GET https://api.zinndigital.com/v1/billing/payment-preferences \
-H "Authorization: Bearer zdk_live_…"Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
The crypto election, the nominated primary/backup, and the two derived answers a billing screen must not compute for itself: whether the account can be charged unattended at all, and whether its backup could actually catch the primary's decline. ⛔ Deliberately **not** part of `GET/PUT /v1/billing/profile`, even though it reads and writes the same row. That endpoint is a documented **full replace**, so folding the crypto election into it would mean a customer correcting a typo in their billing address silently switched their account off crypto — surfacing a month later as an unpaid invoice, with nothing in between to notice it.
