> 500 Internal error. Something went wrong on BlueBot’s side.

| Status             | Code       | Retry?             |
| ------------------ | ---------- | ------------------ |
| 500 Internal error | `internal` | Yes, after waiting |

## What it means

Something went wrong on BlueBot’s side. It was reported. Send the request again; with an Idempotency-Key that is always safe.

## Common causes

- A fault at BlueBot.

## What to do

Try again. If it keeps happening, write to support with the request_id.

## Can I retry it?

Yes, after waiting. Wait the seconds in `retry_after` (or the `Retry-After` header) when the answer has them, otherwise back off from a second or two. With the same `Idempotency-Key`, a retried send never sends twice.

## What the answer looks like

The answer, `500`:

```json
{
  "error": {
    "code": "internal",
    "message": "Something went wrong on our side.",
    "hint": "Try again. If it keeps happening, write to support with the request_id.",
    "doc_url": "https://usebluebot.com/docs/errors/internal",
    "request_id": "req_1Hq2LxW9cVbN3mKpRtYs0a"
  }
}
```

Branch on `code`, which never changes. `message` and `hint` are written for people and may be reworded. Quote `request_id` when you write to support.
