Custom data removed
Incoming webhook deliveries are authenticated with HMAC signature headers (X-Chatway-Signature and X-Chatway-Timestamp), not your Chatway API key.
Custom data was removed from a conversation or contact.
Use custom.data.removed to record a custom-field removal in your activity history. Identify the field from the key in data.custom_data and the actor from data.removed_by. Pair this event with Custom data assigned to record assignments and removals together. For example, track removal of a plan field while retaining the associated contact and conversation records. Use Tag removed for label-removal notifications.
For signature verification and retries, see Webhooks overview.

|---|---|---|---|---|
X-Chatway-Event | header | Yes | string | Event name for this delivery. Example: custom.data.removed |
X-Chatway-Webhook-Id | header | Yes | string (uuid) | Unique webhook subscription ID. Example: 9f3c2a1b-4d5e-4f70-8a9b-0c1d2e3f4a5b |
X-Chatway-Delivery-Id | header | Yes | string | Unique ID for this HTTP delivery attempt (`del_` + 32 hex characters). A new value is sent on each retry. Example: del_1b0279b1f28f12c0b9f2a2fdbf3758ee |
X-Chatway-Delivery-Attempt | header | Yes | string | Attempt number for this event (`1` on first try). Sent as a decimal string in the header. Example: 1 |

X-Chatway-Signature | header | Yes | string | `sha256=` followed by the lowercase hex HMAC SHA256 of `{X-Chatway-Timestamp}.{raw request body}`, keyed with your webhook secret. The example is computed for the example body serialized as compact JSON, the example timestamp, and the placeholder secret `whsec_exampleSecretForDocsOnly00000000`. Example: sha256=951b8f9b1bafab2553ed9b84628fa65ba1e7c4e8b97e5fdff110acd1dff2309d |

Responses
200
Return any 2xx status to acknowledge receipt.
410
Optional HTTP 410 Gone to signal the endpoint is permanently unavailable. Like every non-2xx response below 500 (including 408 and 429), it is not retried. It does not disable the subscription; turn the webhook off in Chatway Settings if you want deliveries to stop.
