Invalid request

What it means

The request body failed validation. The `message` field has the specific reason.

Common causes

• •Missing required field (e.g. `ingredient` on `/v1/check`, `ingredients` on `/v1/formula`).
• •Field has the wrong type (e.g. `events` not an array on `/v1/webhooks`).
• •Body isn't valid JSON.

How to fix

1. 1.Read the `message` field — it states exactly what failed.
2. 2.Cross-check the request schema in the OpenAPI spec at https://regcheck360.com/api/openapi.json.

Example

// 400 response
{
  "error": "invalid_request",
  "message": "ingredients array is required",
  "request_id": "req_…"
}
