Blnk Watch is currently in beta. Send us a message
Use this endpoint when Blnk Core sends transaction events to Watch through a transaction hook. Watch unwraps the webhook payload, injects the transaction, and evaluates it against your active instructions. This follows the same evaluation flow as inject transaction. After processing, use get verdict to read the result, or configure ALERT_WEBHOOK_URL to receive alerts when rules match.
See Getting data into Watch for how to register a Core hook that points at this endpoint.

​
Body

​
string
required
The Blnk webhook event name. For example, transaction.created.
​
object
required
The transaction object from Blnk Core. Field names match Blnk transaction naming - transaction_id, amount, currency, source, destination, created_at, meta_data, and so on.

​
Notes

  • If data.transaction_id is missing, Watch generates a UUID before evaluation.
  • If data.created_at is missing, Watch uses the current server time.
  • On success, the response body is plain text, not JSON.
