generated: '2026-07-17' method: derived source: openapi/signzy-openapi.yml summary: types: - apiKey notes: >- Signzy uses a LoopBack-style token flow. Clients POST a username and API key (as password) to /api/customers/login and receive an access token in the `id` field of the response (with `ttl` and `created`). That token is then sent as the RAW value of the `Authorization` header on subsequent calls - NOT a Bearer token and NOT an HTTP Basic credential. A `?access_token=` query parameter is also accepted but discouraged. Confirmed live: api.signzy.app returns HTTP 401 at root (auth required) on probe 2026-07-17. schemes: - name: accessToken type: apiKey in: header header: Authorization format: raw-token tokenEndpoint: /api/customers/login sources: - openapi/signzy-openapi.yml - https://docs.signzy.com/investor-onboarding-io/authentication - https://docs.signzy.com/generic-onboarding/login-api
