# Recalculate Invoices

> Enqueue async emission recalculation for one or more invoices

# Recalculate Invoices

Enqueue EF-config recalculation for a set of invoices by activity category. The endpoint returns `202 Accepted` immediately and creates one `ProcessingJob` per requested activity category. Invoices remain in their current status while jobs are processing.

<Note>
  All invoice IDs must belong to the caller's organization. IDs that don't match are silently dropped. All surviving invoices must share a single supported type (`heat`, `electricity`, or `recharge`) unless only cross-type categories (e.g. `energy`) are requested.
</Note>

## Request

### Headers

<ParamField header="x-api-key" type="string" required>
  Your API key for authentication

  **Example:** `sk_live_1234567890abcdef`
</ParamField>

  Your organization UUID

  **Example:** `ff4adcc7-8172-45fe-9cf1-e90a6de53aa9`
</ParamField>

### Body Parameters

<ParamField body="invoice_ids" type="array of strings" required>
  One or more invoice UUIDs to recalculate. Must be non-empty.

  **Example:** `["a1b2c3d4-...", "e5f6g7h8-..."]`
</ParamField>

<ParamField body="activity_categories" type="array of strings" required>
  Activity categories to recalculate. Must be non-empty. Duplicates are silently deduplicated.

  **Allowed values:**

  * `stationary` — Scope 1 stationary combustion (heat invoices)
  * `stationary_generation` — Scope 3 heat generation (heat invoices)
  * `electricity` — Scope 2 market-based electricity
  * `electricity_location_based` — Scope 2 location-based electricity
  * `electricity_generation` — Scope 3 electricity generation
  * `electricity_transmission_and_distribution` — Scope 3 T\&D losses
  * `energy` — General energy category (cross-type, heat and electricity only)
  * `recharge` — Scope 1 fugitive emissions from refrigerants (recharge invoices)

  **Example:** `["electricity", "electricity_location_based"]`
</ParamField>

## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Invalid API key for organization", "code": "INVALID_API_KEY"}
```

### 403 Forbidden

**Cause:** The authenticated user is not a member of the organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Logged User is not Member of Organization", "code": "LOGGED_USER_NOT_MEMBER"}
```

### 400 Bad Request

**Cause:** Invoices span multiple types

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Mixed invoice types are not supported",
  "code": "MIXED_INVOICE_TYPES"
}
```

**Cause:** Activity category doesn't match invoice type

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Activity category 'recharge' is not compatible with invoice type 'electricity'",
  "code": "ACTIVITY_CATEGORY_MISMATCH"
}
```
