Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Send POST https://api.copper.com/developer_api/v1/webhooks with required fields target (a valid HTTPS URL), type (entity type: lead, person, company, opportunity, project, or task), and event (new, update, or delete).
Optionally include a secret object (custom key/value pairs echoed with every notification, for verifying the source) and a headers object for custom HTTP headers on each delivery.
Optionally set custom_field_computed_values to true if you want dropdown/multi-select custom fields delivered as option names instead of option IDs.
The response includes the new subscription's id and a created_at Unix timestamp.
You can have up to 100 active subscriptions per account.
Known gotchas
Notifications only ever contain entity IDs, not full record payloads — you must fetch full details separately using the type and IDs from the notification.
There are no automatic retries: a notification fires at most once per event regardless of what your endpoint returns, so build your own reconciliation for missed deliveries.
