# Events and Webhooks You can configure webhook endpoints via APIs or Dashboard in your platform to be notified about events from Column. Each platform can create multiple webhook endpoints for different types of events. All webhook endpoints must be configured with `https` URLs that accept `POST` requests with JSON payloads. > **Warning** > > #### Events limited to single webhook > > Only one webhook endpoint on your platform can receive events of the same type. If you create two endpoints, both of which are configured for all ach event types, only the webhook created first will be notified of ACH events. Please take care to ensure multiple webhook endpoints are configured for different event types. ## Event Object Column event objects all have the same top level structure with unique information related to that event. - `id` unique identifier of an event. If a webhook event is sent multiple times, its `id` will remain the same for all requests. - `created_at` time at which an event was created. - `type` description of an event (see the table below for all types of events). - `data` object containing data associated with an event. Please refer to [All Event Types](#all-event-types) for the `data` object of each event. ```json { "id": "evnt_1vEdMiZ5pmkmrKZfNZ8LeqF2KFP", "created_at": "2021-07-12T23:05:36Z", "type": "ach.outgoing_transfer.completed", "data": { "id": "acht_1vEdMiRjQWQYqRqaOppMfU7BWr1", ... // rest details of ACH transfer object } } ``` ## Authentication To verify that a webhook event was actually sent by Column, every webhook event payload is signed with a signature that is passed through as the HTTP header `Column-Signature`. The signature is a hash-based message authentication code ([HMAC](https://en.wikipedia.org/wiki/HMAC)) with [SHA-256](https://en.wikipedia.org/wiki/SHA-2), by applying the webhook endpoint's signing secret as the key, and the JSON payload (i.e., the request body) as the message. The HTTP header `Webhook-Endpoint-Id` specifies the webhook endpoint ID to which an event is sent. Note, secret keys may not be shared across webhook endpoints. > **Warning** > > #### Warning > > Please use our raw webhook payloads without any modification to calculate signatures. Any pre-processing of our raw webhook payloads (e.g., prettify, deserialize/serialize, trim spaces, etc.) may result in different signatures. All webhook events from Column will be sent from the following IPs, which can be whitelisted in your system: - `44.231.156.17` ## Confirmation & Retry After an event is delivered to a webhook endpoint, and our system receives a `2XX` HTTP response within `10` seconds, that event is considered to have been delivered successfully. If an event delivery failed, our system will retry up to `25` times within `3` days with exponential backoffs. The first retry happens one minute after the original failed delivery. An event may occasionally be delivered multiple times to a webhook endpoint with the same unique event ID. We advise you to guard against duplicated event receipts by making your event processing idempotent. In addition, we suggest you return a `2XX` HTTP response right after an event is received, before you actually process it in your system, to avoid any potential timeout errors. ## Event Ordering Our webhook system does NOT guarantee that events will be delivered in the same order as they are created. For example, the following events might be created for an ACH transfer: - `ach.outgoing_transfer.initiated` - `ach.outgoing_transfer.submitted` - `ach.outgoing_transfer.settled` - `ach.outgoing_transfer.acknowledged` An endpoint should not expect delivery of those events in this order and should handle them accordingly. In most cases, out of order event delivery happens when a previous delivery failed. For example, if our post to your webhook endpoint timed out when we tried to deliver `ach.outgoing_transfer.initiated`, it will be rescheduled with an exponential backoff time. If `ach.outgoing_transfer.submitted` is scheduled before that, and we successfully delivered it to your endpoint, `ach.outgoing_transfer.initiated` will be delivered after `ach.outgoing_transfer.submitted`. You can use our event APIs to fetch any missing or additional events, if necessary. ## Examples ### Setup a webhook endpoint Each webhook endpoint must be configured to accept certain types of events by specifying them in the `enabled_events` list. You can use one webhook endpoint to handle several different event types at once or set up individual endpoints for specific types of events. Wildcard `*` is supported as well. For example, you can use `ach.*` to accept all ACH transfer events, or `*` for all webhook events. Please be careful when using `*`, as it may overload your webhook servers. If multiple endpoints are configured for a certain event type, events of that type will be sent to the first configured endpoint. ```shell curl https://api.column.com/api/webhook_endpoints \ -X POST \ -u : \ -d url="https://example.com/webhook" \ -d description="endpoint for ACH events" \ -d "enabled_events[]"="ach.*" \ -d "enabled_events[]"="book.outgoing_transfer.completed" ``` ### Check the webhook signature Column signs the webhook events sent to your endpoints by including a signature in each event's `Column-Signature` header. This allows you to verify that the events were sent by Column, not by a third party. Before you can verify signatures, you need to retrieve your endpoint's secret from your Dashboard's Webhook settings. Column generates a unique secret key for each endpoint. Once you have the endpoint secret and the raw request body content of a webhook, you can compute an HMAC with the SHA256 hash function, by using the secret as the key and request body as the message. The result should be equal to the value of `Column-Signature` header for a valid webhook event sent by Column. ### Fetch events You can fetch all events (including events that are not sent via webhooks) that happened via our `/api/events` API. If you just want to fetch events that were sent to your webhook endpoints, you can use our `/api/events/webhook` API. Please refer to [All Event Types](#all-event-types) for more information. ### Fetch event delivery history You can fetch the history of webhook deliveries for a certain endpoint or event. The responses of such requests will contain a list of all webhook delivery attempts and their statuses based on query filters. ```json { "webhook_deliveries": [ { "event": { ... // event object defined above }, "scheduled_at": "2021-07-19T17:34:34Z", "status": "SUCCEEDED" }, ... // more webhook delivery attempt ] } ``` ### Protect endpoint secrets Endpoint signing secrets are critical for you to authenticate webhook events from Column. If an endpoint's secret is believed to be compromised, you can create a new webhook subscription endpoint with the same URL and enabled events. Column will continue sending webhook events to the old endpoint until you have updated your system with the new endpoint secret and deleted the old endpoint. At that point, Column will start to send webhook events to the new endpoint. ## All Event Types This is a list of all the types of events we currently create. Note that this list is a work-in-progress. We may add or delete events at any time, so please keep that in mind while developing and maintaining your code. All event types follow a pattern `{category}.{action}` or `{category}.{sub_category}.{action}`. Not all events will be sent via webhook endpoints. Events marked as `WEBHOOK: FALSE` are only created but not sent via webhook. However, you can fetch all types of events via our event APIs. ### Book Transfer Events --- For all Book transfer events, `data` in the webhook response will be the [Book Transfer Object](/api/book-transfer/book-transfer-object) at the time the webhook is fired. `book.transfer.initiated` (`WEBHOOK: FALSE`) Column has received your book transfer request. `book.transfer.completed` Column has processed your book transfer request successfully. This event may be fired directly upon creating a book transfer, or in the case of a hold, when the clear endpoint is called. `book.transfer.hold_created` Column has received your book transfer request with a hold. `book.transfer.updated` Column has updated your book transfer in a hold state successfully. `book.transfer.canceled` Column has canceled your book transfer in a hold state successfully. Funds that were in a hold state because of this transfer are now available. ### ACH Transfer Events --- For all ACH transfer events, `data` in the webhook response will be the [ACH Transfer Object](/api/ach-transfer/ach-transfer-object) at the time the webhook is fired. `ach.outgoing_transfer.initiated` Column has received your ACH transfer request and will submit it to the Federal Reserve Bank at the next settlement window. `ach.outgoing_transfer.manual_review` The transfer is in manual review and will be evaluated by the Column team. `ach.outgoing_transfer.submitted` Column has submitted the ACH transfer request to the Federal Reserve Bank. `ach.outgoing_transfer.settled` The ACH transfer has been settled at the RDFI. For outgoing ACH debit transfers, funds will be available to withdraw once they are settled. `ach.outgoing_transfer.completed` The return window has passed for this ACH transfer, and it is deemed officially completed. In a few very rare cases, it can still be returned by the RDFI with return code `R06` or `R31` ([Return Reason Codes](/ach/returns#return-reason-codes)). `ach.outgoing_transfer.returned` The outgoing ACH transfer has been returned by the RDFI. Return details are available in `ach_transfer.return_details`. `ach.outgoing_transfer.return_dishonored` The return from the RDFI of an outgoing ACH transfer has been dishonored by Column.

Return details are available in `ach_transfer.return_details`. `ach.outgoing_transfer.canceled` The ACH transfer has been canceled before Column submits it to the Federal Reserve Bank per your request. `ach.outgoing_transfer.noc` Column has received a Notification of Change (NOC) from the RDFI that some information about the counterparty should be updated. NOC details are available in `ach_transfer.notification_of_changes`. `ach.incoming_transfer.scheduled` Column has received an incoming ACH transfer (either `credit` or `debit`) from another ODFI, and scheduled to process it on its settlement date. `ach.incoming_transfer.settled` Column has received an incoming ACH transfer (either `credit` or `debit`) from another ODFI, and settled it successfully. `ach.incoming_transfer.nsf` Column attempted to process an incoming ACH debit transfer, but there were insufficient funds in the account. This is usually followed by a returned event. `ach.incoming_transfer.completed` The return window has passed for this incoming ACH transfer, and it is deemed officially completed. In a few very rare cases, you can still request to return it with return code `R06` or `R31` ([Return Reason Codes](/ach/returns#return-reason-codes)). `ach.incoming_transfer.returned` The incoming ACH transfer has been returned by Column. Return details are available in `ach_transfer.return_details`. `ach.incoming_transfer.return_dishonored` The return sent by Column for an incoming ACH transfer has been dishonored by the ODFI. Return details are available in `ach_transfer.return_details`. `ach.incoming_transfer.return_contested` The dishonored return from the ODFI of an incoming ACH transfer has been contested by Column. Return details are available in `ach_transfer.return_details`. ### Wire Transfer Events --- For all Wire transfer events, `data` in the webhook response will be the [Wire Transfer Object](/api/wire-transfer/wire-transfer-object) at the time the webhook is fired. `wire.outgoing_transfer.initiated` Column has received your wire transfer request and will submit it to the Federal Reserve Bank soon. `wire.outgoing_transfer.manual_review` The transfer is in manual review and will be evaluated by the Column team. `wire.outgoing_transfer.submitted` Column has submitted the wire transfer request to the Federal Reserve Bank. `wire.outgoing_transfer.rejected` The wire transfer request has been rejected by Column or by the Federal Reserve _(this event will rarely happen)_. `wire.outgoing_transfer.completed` Column has received an acknowledgement from the Federal Reserve that this wire transfer request has been processed successfully. `wire.incoming_transfer.completed` Column has received an incoming wire transfer (`credit` only) from another ODFI, and processed it successfully. ### Wire Return Request Events --- `wire.incoming_return_request.initiated` Column has received an incoming wire return request. `wire.incoming_return_request.manual_review` The incoming return request was placed in manual review. `wire.incoming_return_request.approved` The incoming return request has been approved, and Column has initiated an outgoing wire to return the funds to the requesting financial institution with the details in the return request. `wire.incoming_return_request.rejected` The incoming return request was rejected. `wire.incoming_return_request.completed` The incoming return request response has been completed. `wire.outgoing_return_request.scheduled` The outgoing return request has been scheduled to be sent. `wire.outgoing_return_request.sent` The outgoing return request has been sent to the Fed. `wire.outgoing_return_request.manual_review` The outgoing return request was placed in manual review. `wire.outgoing_return_request.approved` The outgoing return request has been approved, and the RDFI has initiated an incoming wire to return the funds to Column. `wire.outgoing_return_request.rejected` The outgoing return request was rejected. `wire.outgoing_return_request.completed` The outgoing return request response has been completed. ### Wire Drawdown Events --- For all Wire drawdown events, `data` in the webhook response will be the [Wire Drawdown Object](/api/wire-transfer/wire-drawdown-object) at the time the webhook is fired. `wire.incoming_drawdown_request.received` Column has received an incoming wire drawdown request from another ODFI. `wire.incoming_drawdown_request.approved` The incoming wire drawdown request has been approved, Column will send an outgoing wire. `wire.incoming_drawdown_request.denied` After the wire drawdown request was approved, the outgoing wire was rejected. ### International Wire Transfer Events --- For all International wire events, `data` in the webhook response will be the [International Wire Object](/api/international-wire/international-wire-transfer-object) at the time the webhook is fired, unless specified otherwise. `swift.outgoing_transfer.initiated` Column has received your request and will submit it to the SWIFT network very shortly. `swift.outgoing_transfer.manual_review` Column is manually reviewing your request, and will submit it once it is approved. `swift.outgoing_transfer.submitted` Column has submitted your request to the SWIFT network. `swift.outgoing_transfer.completed` Column has settled the funds to the beneficiary bank or correspondent bank. `swift.outgoing_transfer.pending_return` Column has received the confirmation that your outgoing transfer has been returned.
