invalid_payload

HTTP status: 400 Bad Request
Content-Type: application/problem+json
Error code: invalid_payload

Summary

The webhook request body could not be parsed or was null (e.g. missing or invalid JSON).

When it occurs

• PayPal or Shopify webhook: ReadFromJsonAsync returns null (empty or non-JSON body).
• Body is not valid JSON or does not deserialize to the expected type.

Response shape

Standard error fields only.

Example

{
  "success": false,
  "status": 400,
  "error_code": "invalid_payload",
  "type": "http://commonpark-platform.dev.ordino.global/errors/invalid_payload",
  "title": "Bad request",
  "detail": "The request was unable to be completed due to a problem with the request."
}

How to fix

• Send a valid JSON body that matches the expected webhook payload schema.
• For provider webhooks, ensure the sender is the real provider and the request was not truncated or corrupted.
