Create Customer Domain (Customer)Copy Anchor Link

POST /api/customers/:customerPublicId/domains

Creates a customer domain for expiry monitoring.

Request BodyCopy Anchor Link

{
  "domainName": "deinkunde.com",
  "label": "Main Domain",
  "status": "active",
  "expiryWarningDays": 30,
  "expiryErrorDays": 7
}

Notes:

• customerPublicId should be the customer public UUID. Legacy numeric customer IDs remain supported for compatibility.
• domainName must be a valid domain like deinkunde.com (no protocol, no path).
• Creating an active domain may be blocked by quota limits.

TOKEN="<your-api-token>"

curl -X POST "$BASE_URL/api/customers/6bfec6f6-245a-47ce-843b-157d97d56f88/domains" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"domainName":"deinkunde.com","label":"Main Domain","status":"active","expiryWarningDays":30,"expiryErrorDays":7}'

ResponseCopy Anchor Link

200 with the customer domain record, and the record now carries a deduplicated flag.

Repeating a request with exactly the same body does NOT create a second, separately billable monitor: the entry that already exists is returned again and the response carries "deduplicated": true, while a first creation carries "deduplicated": false. Both cases answer 200. The comparison covers the whole request and not just domainName, so the same domain sent again with a different label, status, expiryWarningDays or expiryErrorDays is a different request and does create a second entry -- there is no uniqueness check on the domain name itself. A recognised repeat consumes no quota and never moves the organization up a quota tier.
