> Noptcha API error unsupported_type (HTTP 400): what it means and what to do.

Source: https://noptcha.com/docs/errors/unsupported_type/

HTTP **400**, `application/problem+json`. When: unknown or unavailable task type.

## What to do

The `type` is unknown or not available. Use the canonical names from [Task types](https://noptcha.com/docs/task-types.md) (for example `recaptcha.v2`); `GET /v1/types` lists the types your organization can use.

See all codes on [Errors](https://noptcha.com/docs/errors.md). Include the `request_id` when you contact support.
