Delete Contact Property

Delete a custom contact property definition.

DELETE /contact-properties/{id}

Compatibility note: DELETE /api/properties/{id} remains available for existing OpenSend integrations; new API clients should prefer the root compatibility path above. Browser dashboard navigation is preserved for page routes that share these names.

Authentication

Use an OpenSend API key in the Authorization header.

http

Authorization: Bearer os_YOUR_API_KEY

Dashboard session cookies are not API credentials.

Parameters

Plan migrations before deleting properties referenced by automations.

Response

Returns an OpenSend JSON response for the authenticated tenant. Error responses use OpenSend error envelopes and standard HTTP status codes.

Self-hosting notes

Self-hosted deployments can use the same path on their own OPENSEND_BASE_URL. Ensure middleware is enabled so API-like requests are routed to /api/properties/{id} while dashboard page requests continue to render normally.
