Standing authorisations

Email the grantor a fresh link to a pending request.

Emails the grantor a fresh link to the mandate; the previous link stops working. Takes no body. At most 3 times in 24 hours (429 authorisation_resend_limited), and only while the request is invited and the grantor has not signed (409 authorisation_not_pending). To change the grantor’s address, cancel the request and send a new one. If the email cannot be delivered, the answer is 503 service_unavailable, not 200: the previous link has already stopped working, and no answer is recorded for the Idempotency-Key, so send the same request again. An undelivered resend does not count towards the limit, but at most 10 are attempted in 24 hours.

Authorizations

Authorization

string

header

required

Authorization: Bearer vsk_live_…. Chosen over a bespoke X-API-KEY header because every client, proxy and log-redaction rule already knows this one. What a key may DO is its scopes — see x-scopes at the root of this document and x-required-scope on each operation. The scope list is not written here because OpenAPI reserves a requirement’s scope array for oauth2 and openIdConnect and requires it to be empty for an http scheme.
