> Notable changes and additions to the cNGN API and its documentation

<Update label="July 23, 2026" description="Webhooks">
  ## Full webhook event coverage

  Every documented [webhook event](/guides/webhooks) is now delivered:

  * **On-chain deposits** now fire `deposit.completed` with `trx_type: crypto_deposit`,
    carrying both the source-network hash (`extl_trx_hash`) and the mint hash
    (`base_trx_hash`). There is no preceding `deposit.received` for on-chain deposits.
  * **Redemptions** now fire `redemption.completed` when the bank payout settles, and
    `transaction.failed` (with `reason: "Provider failed to process payout"`) when it
    does not. Redeemed cNGN is automatically reverted to your balance on payout failure.
  * The [Webhooks guide](/guides/webhooks#sample-payloads-per-event) now documents exact
    sample payloads for all five events, including the three `transaction.failed`
    variants, plus a field-presence matrix.

  ## New endpoint: Bridge Quote

  [`POST /bridge-quote`](/api-reference/bridge-quote) returns the receivable amount,
  network fee, and bridge fee for a cross-network bridge before you commit to it with
  [`POST /bridge`](/api-reference/bridge). Requires the **Swap** permission; the request
  body follows the standard [encrypted wire format](/guides/encryption).
