title: API Evangelist enhancements for Postmark Account Activate Stats/Outbound > Clicks API
version: 1.0.0
x-generated: '2026-08-13'
x-method: generated
x-source: derived from authentication/postmark-authentication.yml, errors/postmark-problem-types.yml and
conventions/postmark-conventions.yml against openapi/postmark-stats-outbound-clicks-api-openapi.yml
x-note: 'Non-destructive. The underlying OpenAPI is never mutated. Every action below adds something Postmark
documents on postmarkapp.com but does not express in the machine-readable contract: the two authentication
schemes, the https scheme on the server URL (the harvested spec carries a protocol-relative "//api.postmarkapp.com/"),
contact/licence metadata, and the six documented HTTP error statuses missing from every operation.'

plain HTTP on 2022-09-01; the harvested spec carries a scheme-relative server URL that is not a valid
absolute URL.

description: Declare the two API token schemes. Every Postmark spec in this repo ships with no securitySchemes
at all, so a generator reading the spec alone emits an unauthenticated client.

securitySchemes:

Removal.

422 and 500; Postmark also documents 401, 404, 413, 415, 429 and 503.
update:
