+restapi: true
+---
+
+## Introduction
+
+The Certificate API allows company admins to manage [landscape-wide (central) certificates](/developerportal/deploy/certificates/centralized-certificates/) via API. These certificates are used to configure custom domains on Mendix Cloud and can also be managed via [Certificate Management](/control-center/certificate-management/) in Control Center.
+
+{{% alert color="info" %}}
+The Certificate API does not manage local or app-level certificates. [App-level certificates](/developerportal/deploy/application-level-certificates/) are configured via Cloud Portal.
+{{% /alert %}}
+
+## Prerequisites
+
+To use the Certificate API, you must:
+
+* Be a company admin
+* Have a Mendix Personal Access Token (PAT) with the `mx:deployment:write` scope
+
+For information on creating a PAT, see [Personal Access Tokens](/mendix-profile/user-settings/#pat).
+
+## Capabilities
+
+The Certificate API lets you manage the central certificates owned by your company:
+
+| Capability | Method and Path |
+| --- | --- |
+| List certificates | `GET /v1/certificates` |
+| Create a certificate | `POST /v1/certificates` |
+| Update a certificate | `PATCH /v1/certificates/{certificateId}` |
+| Replace a certificate | `PUT /v1/certificates/{certificateId}/replacement` |
+| Delete a certificate | `DELETE /v1/certificates/{certificateId}` |
+
+All endpoints operate only on central certificates. Private key material, certificate PEM data, and internal identifiers are never returned in any response.
+
+## Base URL
+
+```
+https://api.home.mendix.com/
+```
+
+## Authentication
+
+All requests must include your PAT in the `Authorization` header:
+
+```
+Authorization: mxToken <PAT>
+```
+
+The company that a request operates on is derived automatically from the authenticated token and you do not pass a company identifier. Every operation is scoped to and restricted to the certificates owned by that company.
+
+## Certificate Object
+
+Successful responses return a certificate object with the following structure:
+
+```json
+{
+  "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
+  "description": "Wildcard cert for example.com",
+  "validFrom": "2026-01-01T00:00:00Z",
+  "validTill": "2027-01-01T00:00:00Z",
+  "createdAt": "2026-01-02T09:15:00Z",
+  "updatedAt": "2026-01-02T09:15:00Z",
+  "status": "VALID",
+  "inUse": true,
+  "linkedFqdnsCount": 2
+}
+```
+
+| Field | Type | Description |
+| --- | --- | --- |
+| `id` | String (UUID) | Unique certificate identifier |
+| `description` | String | Free-text description (auto-generated from the certificate's subject/SAN if not supplied) |
+| `validFrom` | String (RFC3339) | Certificate validity start |
+| `validTill` | String (RFC3339) | Certificate validity end |
+| `createdAt` | String (RFC3339) | When the certificate was created |
+| `updatedAt` | String (RFC3339) | When the certificate was last modified |
+| `status` | String enum | One of `UPCOMING`, `VALID`, `EXPIRES SOON`, `EXPIRED`. Computed from validity dates; `EXPIRES SOON` applies within 15 days of expiry |
+| `inUse` | Boolean | `true` if the certificate is linked to one or more custom domains |
+| `linkedFqdnsCount` | Integer | Number of custom domains currently linked to this certificate |
+
+## Errors
+
+All errors use a standard envelope:
+
+```json
+{
+  "error": {
+    "message": "certificate not found",
+    "code": 404,
+    "detail": "optional additional context"
+  }
+}
+```
+
+| Status | Meaning |
+| --- | --- |
+| 400 | Malformed request – invalid certificate or key, certificate/key mismatch, invalid chain, invalid query parameter, or the certificate has linked domains and cannot be deleted |
+| 401 | Missing or invalid authentication |
+| 404 | Certificate not found, or not owned by your company |
+| 409 | Conflict – a certificate with the same key material already exists |
+| 500 | Internal server error |
+
+## Endpoints
+
+### List Certificates {#list-certificates}
+
+```
+GET /v1/certificates
+```
+
+Returns the central certificates owned by your company, most recently updated first. Supports filtering and pagination.
+
+#### Query Parameters
+
+| Parameter | Type | Default | Notes |
+| :---: | :---: | :---: | --- |

+| `status` | String | – | Filter by status: `UPCOMING`, `VALID`, `EXPIRES SOON`, `EXPIRED` |
+| `page` | integer | 1 | 1-based page number |
+| `limit` | integer | 10 | Page size, 1–100 |
+
+**Response 200:**
+
+```json
+{
+  "certificates": [ { "...": "certificate object" } ],
+  "page": 1,
+  "limit": 10,
+  "totalCount": 3
+}
+```
+
+### Create a Certificate {#create-certificate}
+
+```
+POST /v1/certificates
+```
+
+#### Request Body
+
+```json
+{
+  "certificate": "-----BEGIN CERTIFICATE-----...",
+  "privateKey": "-----BEGIN PRIVATE KEY-----...",
+  "intermediateChain": "-----BEGIN CERTIFICATE-----...",
+  "description": "Wildcard cert for example.com"
+}
+```
+
+| Field | Required | Notes |
+| --- | :---: | --- |
+| `certificate` | Yes | PEM-encoded leaf certificate |
+| `privateKey` | Yes | PEM-encoded private key matching the certificate |
+| `intermediateChain` | No | PEM-encoded intermediate chain |
+| `description` | No | Auto-generated from the certificate if omitted |
+
+{{% alert color="info" %}}
+Certificates generated from a Mendix-issued CSR are not supported by this endpoint.
+{{% /alert %}}
+
+**Response:** 201 with the created certificate object.
+
+### Update a Certificate {#update-certificate}
+
+```
+PATCH /v1/certificates/{certificateId}
+```
+
+Partially updates a certificate's material or description. Any combination of fields may be supplied.
+
+#### Request Body
+
+```json
+{
+  "certificate": "-----BEGIN CERTIFICATE-----...",
+  "intermediateChain": "-----BEGIN CERTIFICATE-----...",
+  "description": "Renewed cert"
+}
+```
+
+**Response:** 200 with the updated certificate object.
+
+### Replace a Certificate {#replace-certificate}
+
+```
+PUT /v1/certificates/{certificateId}/replacement
+```
+
+Rotates a certificate – transfers all custom domains linked to `{certificateId}` onto another certificate you own, without downtime for the linked domains. Both certificates must be central certificates owned by your company.
+
+#### Request Body
+
+```json
+{"newCertificateId": "8f14e45f-ceea-467e-8459-b17dc4536f43"}
+```
+
+**Response:** 200 with the new certificate's object (now carrying the transferred domain links).
+
+### Delete a Certificate {#delete-certificate}
+
+Deletes a central certificate.
+
+```
+DELETE /v1/certificates/{certificateId}
+```
+
+{{% alert color="warning" %}}
+A certificate that is still linked to one or more custom domains cannot be deleted. Replace or unlink it first.
+{{% /alert %}}
+
+**Response:** 204 No Content
