# Internal account status webhook

`POST internal-account-status` (webhook)

Webhook that is called when the status of an internal account changes. This includes balance updates and may include additional account events in the future.
This endpoint should be implemented by clients of the Grid API.

### Authentication
The webhook includes a signature in the `X-Grid-Signature` header that allows you to verify that the webhook was sent by Grid.
To verify the signature:
1. Get the Grid public key provided to you during integration
2. Decode the base64 signature from the header
3. Create a SHA-256 hash of the request body
4. Verify the signature using the public key and the hash

If the signature verification succeeds, the webhook is authentic. If not, it should be rejected.

### Event types
- `INTERNAL_ACCOUNT.BALANCE_UPDATED` — Fired when the balance of an internal account changes. The `data` payload contains the full internal account object.
- `INTERNAL_ACCOUNT.STATUS_UPDATED` — Fired when the status of an internal account changes (e.g., `OPEN` → `FROZEN`). The `data` payload contains the full internal account object.

## Payload

- InternalAccountStatusWebhook
  - `id` string, required — Unique identifier for this webhook delivery (can be used for idempotency)
  - `type` 'INTERNAL_ACCOUNT.BALANCE_UPDATED' | 'INTERNAL_ACCOUNT.STATUS_UPDATED', required — Type of webhook event in OBJECT.EVENT dot-notation. The part before the dot identifies the resource, the part after identifies the event. This lets consumers route purely on type without inspecting data.status.
  - `timestamp` string, date-time, required — ISO 8601 timestamp of when the webhook was sent
  - `data` InternalAccount, required
    - `id` string, required — The ID of the internal account
    - `customerId` string — The ID of the customer associated with the internal account. If this field is empty, the internal account belongs to the platform.
    - `type` 'INTERNAL_FIAT' | 'INTERNAL_CRYPTO' | 'EMBEDDED_WALLET', required — Classification of an internal account. - `INTERNAL_FIAT`: A Grid-managed fiat holding account (for example, the USD holding account used as the source for Payouts flows). - `INTERNAL_CRYPTO`: A Grid-managed crypto holding account denominated in a stablecoin such as USDC. - `EMBEDDED_WALLET`: A self-custodial Embedded Wallet provisioned for the customer. Outbound transfers require a session signature produced by the customer's device — see the Embedded Wallets guide.
    - `status` 'PENDING' | 'ACTIVE' | 'CLOSED' | 'FROZEN' | 'FAILED', required — Status of a Grid internal account. The status determines whether the account can send or receive payments. - `PENDING`: The account is under review and is being provisioned. The account cannot send or receive payments until provisioning completes. - `ACTIVE`: The account is ready to send and receive payments. - `CLOSED`: The account cannot send or receive payments. A customer can initiate the closing of an internal account, after which the account transitions to this status. - `FROZEN`: The account cannot send or receive payments. Grid may freeze an account in response to compliance or fraud signals; payments are blocked while the account remains frozen. - `FAILED`: The account could not be provisioned. Grid was unable to create the underlying account, so it cannot send or receive payments and requires remediation.
    - `balance` CurrencyAmount, required
      - `amount` integer, required — Amount in the smallest unit of the currency (e.g., cents for USD/EUR, satoshis for BTC)
      - `currency` Currency, required
        - `code` string — Three-letter currency code (ISO 4217) for fiat currencies. Some cryptocurrencies may use their own ticker symbols (e.g. "BTC" for Bitcoin, "USDC" for USDC, etc.)
        - `name` string — Full name of the currency
        - `symbol` string — Symbol of the currency
        - `decimals` integer — Number of decimal places for the currency
    - `totalBalance` CurrencyAmount, required
      - `amount` integer, required — Amount in the smallest unit of the currency (e.g., cents for USD/EUR, satoshis for BTC)
      - `currency` Currency, required
        - `code` string — Three-letter currency code (ISO 4217) for fiat currencies. Some cryptocurrencies may use their own ticker symbols (e.g. "BTC" for Bitcoin, "USDC" for USDC, etc.)
        - `name` string — Full name of the currency
        - `symbol` string — Symbol of the currency
        - `decimals` integer — Number of decimal places for the currency
    - `fundingPaymentInstructions` PaymentInstructions[], required — Payment instructions for funding the account — unresolved $ref
    - `privateEnabled` boolean — Whether wallet privacy is enabled for the Embedded Wallet. Only present for `EMBEDDED_WALLET` internal accounts.
    - `createdAt` string, date-time, required — Timestamp when the internal account was created
    - `updatedAt` string, date-time, required — Timestamp when the internal account was last updated
