A provider is an outbound channel: an SMTP or e-mail service that carries verification and password-reset mail, an SMS service that carries MFA codes, or an OAuth identity provider people sign in through. Filter with `category` — `Email`, `SMS` or `OAuth`. Read-only: nothing changes. A provider listed here is configured but not necessarily in USE — what makes it live is being linked to an application (`GET /v1/applications/{id}/providers`). Failures: - `400 IDE-0018` — `limit` is above the deployment's maximum (100 by default). - `400 IDE-0019` — `page` is below 1. - `503 IDE-0066` — the identity provider is unavailable (unreachable, too slow to answer, or failing). Nothing about the request was wrong; retry it later. ## OpenAPI ````yaml /pt/openapi/v3-current/AM-identity.yaml get /v1/providers openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: OpenAPI 3.1 surface for the Access Manager identity component. license: name: Lerian Studio General License title: Access Manager Identity API version: v1 servers: - url: https://identity.sandbox.lerian.net security: [] tags: - description: >- M2M-only: each plugin declares its own permissions, roles and M2M contract, and the server reconciles them. name: Declarations - description: >- A tenant administrator's customers.
