# Create a provider

`POST /providers`

Configures a provider integration from a Courier provider key and its settings. Check the catalog endpoint for the schema each provider expects.

## Headers

- `Idempotency-Key` string
- `x-idempotency-expiration` string

## Request body

- ProvidersCreateRequest — Request body for creating a new provider configuration.
  - `provider` string, required — The provider key identifying the type (e.g. "sendgrid", "twilio"). Must be a known Courier provider — see the catalog endpoint for valid keys.
  - `title` string — Optional display title. Omit to use "Default Configuration".
  - `alias` string — Optional alias for this configuration.
  - `settings` object — Provider-specific settings (snake_case keys). Defaults to an empty object when omitted. Use the catalog endpoint to discover required fields for a given provider — omitting a required field returns a 400 validation error.
