The three account-lifecycle events were renamed from `bank_account.*` to `account.*`, and the payload embed key from `bank_account` to `financial_account`. The legacy `bank_account.*` event names remain available so existing integrations keep working — endpoints with `payload_version=v1` receive the legacy variant. The other events (`transactions.*`, `balance.updated`, `holdings.updated`) have the same event-type string in both versions; only the payload embed key differs between v1 and v2. enum: - transactions.created - transactions.updated - balance.updated - holdings.updated - account.created - account.updated - account.deleted - bank_account.created - bank_account.updated - bank_account.deleted - connection.created - connection.activated - connection.reauthorized - connection.expiring - connection.expired - connection.failing - connection.recovered - connection.disabled - connection.deleted - portal.user.verified title: WebhookEventTypeEnum responses: AuthenticationException: description: Unauthenticated content: application/json: schema: type: object properties: message: type: string description: Error overview. required: - message AuthorizationException: description: Authorization error content: application/json: schema: type: object properties: message: type: string description: Error overview. required: - message ModelNotFoundException: description: Not found content: application/json: schema: type: object properties: message: type: string description: Error overview. required: - message ValidationException: description: Validation error content: application/json: schema: type: object properties: message: type: string description: Errors overview. errors: type: object description: A detailed description of each field that failed validation. additionalProperties: type: array items: type: string required: - message - errors securitySchemes: oauth2: type: oauth2 flows: authorizationCode: authorizationUrl: https://api.synci.io/oauth/authorize tokenUrl: https://api.synci.io/oauth/token scopes: profile:read: View your name, email, and profile details accounts:read: View your connected financial accounts and balances accounts:write: >- Update, sync, and remove your financial accounts, and change their settings transactions:read: View your transactions transactions:write: Create, update, and delete your transactions sensitive:read: >- See sensitive identifiers like account numbers and account holder names transfer-links:read: View your transfer links and their transfer history transfer-links:write: Create, update, and delete transfer links, and undo transfers rules:read: View your rules and rule activity rules:write: Create, update, and delete rules, and undo rule actions webhooks:read: View your webhook endpoints webhooks:write: >- Create, update, and delete webhook endpoints, and rotate their secrets destinations:read: View your connected destinations destinations:write: Connect, update, and remove destinations financial-connections:read: View your connected institutions financial-connections:write: Manage your connected institutions http: type: http description: Bearer token (personal access token or OAuth access token) scheme: bearer ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
