Basic information

CloudDNS service can be managed using REST API. The API offers all the capabilities of the customer administration. It communicates using JSON format with UTF-8 encoding.

In order to use CloudDNS API, you need an active user the customer administration, that has permissions for CloudDNS. You can get access tokens for communication with CloudDNS API by logging in against the customer administration API.

API usage examples

There are several simple PHP examples on how to use CloudDNS API available in the examples directory. To run them locally, you have to execute composer install, which installs the necessary dependencies.

Authentization

All API access points require a valid accessToken sent in header, as per the oAuth2.0 standard. CloudDNS API supports only Bearer token type.

An example call to load domain details:

GET /clouddns/domain/csFHCU9OROKEmRxyVekn-Q HTTP/2
Host: admin.vshosting.cloud
Content-Type: application/json
Authorization: Bearer oenCToMxTrSEgmHShDJLew
Cache-Control: no-cache

where "oenCToMxTrSEgmHShDJLew" is the value of temporary valid accessToken. If accessToken is invalid or expired, the API returns the following error:

{
   "error":{
      "code":401,
      "message":"Not authorized."
   }
}

You can get accessToken and refreshToken by calling POST /auth/login against customer administration API.

In order to communicate with the API, you need to create a user with permissions for the CloudDNS service in the customer administration. After creating a user, you need to confirm the registration e-mail sent to them. A user with pending confirmation cannot access CloudDNS API.

POST /auth/login

PARAMETER NAME	DATA TYPE	REQUIRED	EXAMPLE	SOURCE
email	string	true	[email protected]	body
password	string	true	HO0s88QGT869dEaMDEAFoQ	body

Example of a login call:

POST /api/public/auth/login HTTP/2
Host: admin.vshosting.cloud
Content-Type: application/json
Cache-Control: no-cache

{
   "email":"[email protected]",
   "password":"z!bze$yn&Ug6^=Jp"
}

If the login is successful, the API returns accessToken and refreshToken. accessToken is valid for 30 minutes. refreshToken expires after 60 minutes. accessToken must be included in the header of every request. To get a new set of tokens, you must make a call to POST /auth/refresh before refreshToken expires. This endpoint returns the same response as POST /auth/login. If refreshToken is expired, you need to login again using the POST /auth/login endpoint.

API limits

• The number of API queries is not limited, but the excessive usage of the API in order to overload the application will not be tolerated
• the number of failed requests to restore oAuth tokens is limited to 10,000 attempts per hour from one IP address
• the number of failed requests with an invalid accessToken is limited to 10,000 attempts per hour from one IP address

In case of login failure (incorrect credentials) or in case of reaching the limit above, the API will keep returning an error for all subsequent requests from the same IP address

{
    "error": {
        "code": 405,
        "message": "Potentially fraud behaviour detected. Please provide additional validation by Google reCaptcha."
    }
}

To release the blockage, it is necessary to open the user interface of the application, and properly send the captcha on the login page. Alternatively, it is necessary to wait for a release of the blockage that will be made in 1 hour from 1st undesirable requirement.

API response types

API returns several different responses, depending on the action type and whether the data sent to the API was valid.

Response reporting success

For example deleting a domain via DELETED /clouddns/domain/{id}.

{
   "success": true
}

Response with current entity object

For example editing A record via PUT /clouddns/record-a/{id}.

{
   "id":"RCFyDiTXSOiyrTqHLt0F-A",
   "domainId":"naAPLQIaSDGiNOjsmepL3A",
   "originalDomainRecordId":null,
   "status":"ACTIVE",
   "name":"efdsf.bb2.cz.",
   "class":"IN",
   "type":"A",
   "originApplicationType":"CLOUDDNS",
   "originUserFullName":"M C",
   "created":"2019-10-29T08:25:27Z",
   "lastUpdate":"2019-11-15T14:11:17Z",
   "value":"8.8.8.2"
}

Business logic error code

{
   "error":{
      "code":2001,
      "message":"Invalid user credentials"
   }
}

Validation error for invalid input parameters

For example sending an API request with missing parameters.

{
    "error": {
        "code": 400,
        "message": "invalid user input",
        "meta": [
            {
                "parameter": "clientId",
                "message": "field is required",
                "code": 100
            },
            {
                "parameter": "domainName",
                "message": "field is required",
                "code": 100
            }
        ]
    }
}

Roles and permissions

In order to communicate with CloudDNS API, you need to create a user with permissions for the CloudDNS service in the customer administration. After creating the user, confirm the registration e-mail. User with pending confirmation cannot access CloudDNS API.

The user must have one of the following roles:

• MANAGER - in the customer administration, this role is shown as “Administrator”
• TECHNICAL_USER - in the customer administration, this role is shown as “Technical administrator”

The user must have the following options enabled:

• cloudDnsEnabled - in the customer administration, this option is shown as “Can manage domains in CloudDNS?”
• accessToClientZone - in the customer administration, this option is shown as “Can log in under your user account?“

Both roles and their settings can be editted after creating the account. The change in permissions will take place after refreshing token or upon logging in.

If the user does not have sufficient permissions, the API returns an error:

{  
   "error":{  
      "code":402,
      "message":"Insufficient privileges."
   }
}

The customer administration lets user to be connected to multiple clients. Owing that, a user can use one accessToken to execute API calls on all clients that they have CloudDNS permissions for.

UUID

CloudDNS has unique identifiers for all records created by the system. It uses random UUID generator based on RFC4122 v4 and converted to a URL-safe string with 22 characters.

Creating a domain

To create a domain, you need to enter a domain name and a client id. If successful, the response will return a domain object.

POST /clouddns/domain

PARAMETER NAME	DATA TYPE	REQUIRED	EXAMPLE	SOURCE
accessToken	string	true	oenCToMxTrSEgmHShDJLew	header
clientId	string	true	HO0s88QGT869dEaMDEAFoQ	body
domainName	string	true	example.cz.	body

Domain status

Status	Explanation
NEW	New domain, records are waiting for publication.
PUBLISHING_TO_INTERNET	Domain has been published to the Internet. After TTL runs out, its availability will automatically checked.
WAITING_TO_TTL	Changes in DNS records have been published to the Internet. After TTL runs out, the changes will be automatically checked.
ACTIVE	Domain is active and available in the Internet.
DEACTIVATED	Domain has been deactivated by user and is not being published.
DELETED	Domain has been marked for deletion and is not being published. It will be irreversibly deleted in 14 days.
DOMAIN_NOT_HEADING_TO_VSHOSTING	Domain does not have correct NS records and probably does not use CloudDNS servers.
DOMAIN_NOT_AVAILABLE	Domain is not available in the Internet.
WARNING	SOA serial check was not successful.

The automatically checks domains and swiches between ACTIVE, DOMAIN_NOT_AVAILABLE, DOMAIN_NOT_HEADING_TO_VSHOSTING, DOMAIN_NOT_AVAILABLE and WARNING states based on availability.

After calling POST /clouddns/domain/{id}/publish, the changes to PUBLISHING_TO_INTERNET and WAITING_TO_TTL states.

You can switch a domain to the DEACTIVATED state by calling PUT /clouddns/domain/{id}/deactivated.

A domain enters DELETED state after DELETE /clouddns/domain/{id} is called.

Listing domains

Domain listing supports pagination, filtering and ordering. Pagination is controlled by the limit and offset parameters. Sorting is controlled by sort parameter
You can filter the results using search parameter. This parameter accepts an object array with the following parameters:

• name - attribute name; used for searching
• operator - filter operator name
• type - default data type
• value - desired value

To get a list of attributes you can search over, please call GET /clouddns/search/columns. This returns a list of available attributes and filter operators.

Supported filter operators

Operator	Meaning
eq	equality
ne	unequality
search	fulltext search
lt	less than
lte	less than or equal
gt	greater than
gte	greater than or equal

Domains can be sorted by attributes in asceding or descending order using the sort parameter.

POST /clouddns/domain/search

Domain details and DNS records overview

Information about domain's DNS records is available through GET /clouddns/domain/{id} endpoint. The returned object includes activeDomainRecordList and lastDomainRecordList fields.

activeDomainRecordList includes domain's published DNS records.
lastDomainRecordList has the same structure as activeDomainRecordList. It includes unpublished changes in DNS records.

After calling PUT /clouddns/domain/{id}/publish, the changed in DNS records will be published to the Internet. When publishing records, the contents of lastDomainRecordList are copied over to activeDomainRecordList and new lastDomainRecordList is created with currently valid records. After publishing a domain, activeDomainRecordList and lastDomainRecordList will be identical.

Other domain operations

A domain can be deleted, deactivated and restored.

Domain can be deleted using DELETE /clouddns/domain/{id} endpoint. It can be recovered via PUT /clouddns/domain/{id}/recover within 14 days.

You can deactivate a domain using PUT /clouddns/domain/{id}/deactivate. Deactivated domains are not published to the Internet. You can reactivate the domain by calling PUT /clouddns/domain/{id}/activate.

All changes since last published version can be rolled back using PUT clouddns/domain/{id}/reset-changes.

Adding, editing and deleting DNS records

CloudDNS API supports the following records: A, AAAA, CNAME, MX, TXT, SRV, CAA, SSHFP, TLSA.

The various endpoints serve for adding, editing and deleting DNS records of the latest version of a domain. Changes made by these endpoints have no effect on the working copy of the domain. They become valid only after calling PUT /clouddns/domain/{id}/publish.

You need to keep on mind, that when you publish the changes using PUT /clouddns/domain/{id}/publish, IDs of all of the domain's records will be changed (due to versioning). If you want to edit/delete another DNS record, you need to load the domain's details again, search for the DNS record in lastDomainRecordList field and use the given ID.

Endpoints for adding and editing DNS records of A, AAAA, CNAME, TXT type accept the same input parameters

PARAMETER NAME	DATA TYPE	REQUIRED	EXAMPLE	SOURCE
accessToken	string	true	oenCToMxTrSEgmHShDJLew	header

Deleting and restoring a DNS record

You can delete DNS records using DELETE /clouddns/record/{id} endpoint. The only input is the record's id from lastDomainRecordList field returned by GET /clouddns/domain/{id}. If deletion has not been published yet, you can restore the record by calling PUT /clouddns/record/{id}/recover.

Publishing DNS records changes

PUT /clouddns/domain/{id}/publish endpoint serves for publishing newly added, changed or deleted DNS records. GET /clouddns/domain/{id} endpoint returns lastDomainVersionRecordsChanged attribute. If the attribute is true, there are unpublished changes in DNS records.

PUT /clouddns/domain/{id}/publish

PARAMETER NAME	DATA TYPE	REQUIRED	EXAMPLES	SOURCE

}

Batch update of DNS records

By calling PUT /clouddns/domain/{id}/records you can update all DNS records of a domain. As input, send a list of all DNS records that should be published. The system validates the input, updates all DNS records served in input and publishes the changes. There is no need to call PUT /clouddns/domain/{id}/publish after a batch update.

      }
   ]
}

Activation and management of DNSSEC

You can activate DNSSEC via PUT /clouddns/domain/{id}/dnssec-activate.

Following that, you retrieve DNSSEC public key by calling GET /clouddns/domain/{id}/public-key.

For .cz domains, you can publish the public key directly using PUT /clouddns/domain/{id}/publish-public-key. The change at your domain registrar should take place within 14 days.

PUT /clouddns/domain/{id}/dnssec-reg-status enpoint returns the current status of DNSSEC publication. It returns a domain object that contains a dnssec object with the following fields:

{
   "dnsSec":{
      "enabledDate": <dateTime>,
      "published": <bool>,
      "publishedDate": <dateTime>,
      "regStatus": <string>,
      "regStatusDate": <dateTime>
   }
}

Attribute	Meaning
enabledDate	date of DNSSEC activation
published	marks whether the key has been published
publishedDate	date of DNSSEC publication
regStatus	state of DNSSEC publication
regStatusDate	date of the last DNSSEC check

Various states of regStatus

regStatus	Meaning
UNKNOWN	DNSSEC public key has not been verified yet
REG_NO_DNSSEC_KEY	No public key found at your registrar
REG_INVALID_DNSSEC_KEY	Public key at your registrar does not match the DNSSEC key in CloudDNS
OK	Public key has been successfully verified, DNSSEC is active

Publication of DNSSEC key can be cancelled by calling PUT /clouddns/domain/{id}/revoke-public-key.

DNSSEC can be deactivated via PUT /clouddns/domain/{id}/dnssec-deactivate.
