AdGuard Home API Change Log

v0.108.0: API changes

v0.107.15: POST Requests Without Bodies

As an additional CSRF protection measure, AdGuard Home now ensures that requests that change its state but have no body do not have a Content-Type header set on them.

This concerns the following APIs:

• POST /control/dhcp/reset_leases;
• POST /control/dhcp/reset;
• POST /control/parental/disable;
• POST /control/parental/enable;
• POST /control/querylog_clear;
• POST /control/safebrowsing/disable;
• POST /control/safebrowsing/enable;
• POST /control/safesearch/disable;
• POST /control/safesearch/enable;
• POST /control/stats_reset;
• POST /control/update.

v0.107.14: BREAKING API CHANGES

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered. We have implemented several measures to prevent such vulnerabilities in the future, but some of these measures break backwards compatibility for the sake of better protection.

All JSON APIs that expect a body now check if the request actually has Content-Type set to application/json.

All new formats for the request and response bodies are documented in openapi.yaml.

POST /control/filtering/set_rules And Other Plain-Text APIs

The following APIs, which previously accepted or returned text/plain data, now accept or return data as JSON.

POST /control/filtering/set_rules

Previously, the API accepted a raw list of filters as a plain-text file. Now, the filters must be presented in a JSON object with the following format:

{
  "rules":
  [
    "||example.com^",
    "# comment",
    "@@||www.example.com^"
  ]
}

GET /control/i18n/current_language And POST /control/i18n/change_language

Previously, these APIs accepted and returned the language code in plain text. Now, they accept and return them in a JSON object with the following format:

{
  "language": "en"
}

POST /control/dhcp/find_active_dhcp

Previously, the API accepted the name of the network interface as a plain-text string. Now, it must be contained within a JSON object with the following format:

{
  "interface": "eth0"
}

v0.107.12: API changes

GET /control/blocked_services/services

• The new GET /control/blocked_services/services HTTP API allows inspecting all available services.

v0.107.7: API changes

The new optional field "ecs" in QueryLogItem

• The new optional field "ecs" in GET /control/querylog contains the IP network from an EDNS Client-Subnet option from the request message if any.

The new possible status code in /install/configure response.

• The new status code 422 Unprocessable Entity in the response for POST /install/configure which means that the specified password does not meet the strength requirements.

v0.107.3: API changes

The new field "version" in AddressesInfo

• The new field "version" in GET /install/get_addresses is the version of the AdGuard Home instance.

v0.107.0: API changes

The new field "cached" in QueryLogItem

• The new field "cached" in GET /control/querylog is true if the response is served from cache instead of being resolved by an upstream server.

New constant values for filter_list_id field in ResultRule

• Value of 0 is now used for custom filtering rules list.

• Value of -1 is now used for rules generated from the operating system hosts files.

• Value of -2 is now used for blocked services' rules.

• Value of -4 is now used for rules generated by safe browsing web service.

• Value of -5 is now used for rules generated by safe search web service.

New possible value of "name" field in QueryLogItemClient

• The value of "name" field in GET /control/querylog method is never empty: either persistent client's name or runtime client's hostname.

Lists in AccessList

• Fields "allowed_clients", "disallowed_clients" and "blocked_hosts" in POST /access/set now should contain only unique elements.

• Fields "allowed_clients" and "disallowed_clients" cannot contain the same elements.

The new field "private_key_saved" in TlsConfig

• The new field "private_key_saved" in POST /control/tls/configure, POST /control/tls/validate and GET /control/tls/status is true if the private key was previously saved as a string and now the private key omitted from communication between server and client due to security issues.

The new field "cache_optimistic" in DNS configuration

• The new optional field "cache_optimistic" in POST /control/dns_config method makes AdGuard Home use or not use the optimistic cache mechanism.

• The new field "cache_optimistic" in GET /control/dns_info method is true if AdGuard Home uses the optimistic cache mechanism.

New possible value of "interval" field in QueryLogConfig

• The value of "interval" field in POST /control/querylog_config and GET /control/querylog_info methods could now take the value of 0.25. It's equal to 6 hours.

• All the possible values of "interval" field are enumerated.

• The type of "interval" field is now number instead of integer.

ClientIDs in Access Settings

• The POST /control/access/set HTTP API now accepts ClientIDs in "allowed_clients" and "disallowed_clients" fields.

The new field "unicode_name" in DNSQuestion

• The new optional field "unicode_name" is the Unicode representation of question's domain name. It is only presented if the original question's domain name is an IDN.

Documentation fix of DNSQuestion

• Previously incorrectly named field "host" in DNSQuestion is now named "name".

Disabling Statistics

• The POST /control/stats_config HTTP API allows disabling statistics by setting "interval" to 0.

POST /control/dhcp/reset_leases

• The new POST /control/dhcp/reset_leases HTTP API allows removing all leases from the DHCP server's database without erasing its configuration.

The parameter "host" in GET /apple/*.mobileconfig is now required.

• The parameter "host" in GET requests for /apple/doh.mobileconfig and /apple/doh.mobileconfig is now required to prevent unexpected server name's value.

The new field "default_local_ptr_upstreams" in GET /control/dns_info

• The new optional field "default_local_ptr_upstreams" is the list of IP addresses AdGuard Home would use by default to resolve PTR request for addresses from locally-served networks.

The field "use_private_ptr_resolvers" in DNS configuration

• The new optional field "use_private_ptr_resolvers" of "DNSConfig" specifies if the DNS server should use "local_ptr_upstreams" at all.

v0.106: API changes

The field "supported_tags" in GET /control/clients

• Previously undocumented field "supported_tags" in the response is now documented.

The field "whois_info" in GET /control/clients

• Objects in the "auto_clients" array now have the "whois_info" field.

New response code in POST /control/login

• 429 is returned when user is out of login attempts. It adds the Retry-After header with the number of seconds of block left in it.

New "private_upstream" field in POST /test_upstream_dns

• The new optional field "private_upstream" of UpstreamConfig contains the upstream servers for resolving locally-served ip addresses to be checked.

New fields "resolve_clients" and "local_ptr_upstreams" in DNS configuration

• The new optional field "resolve_clients" of DNSConfig is used to turn resolving clients' addresses on and off.

• The new optional field "local_ptr_upstreams" of "DNSConfig" contains the upstream servers for resolving addresses from locally-served networks. The empty "local_ptr_resolvers" states that AGH should use resolvers provided by the operating system.

New "client_info" field in GET /querylog response

• The new optional field "client_info" of QueryLogItem objects contains a more full information about the client.

v0.105: API changes

New "client_id" field in GET /querylog response

• The new field "client_id" of QueryLogItem objects is the ID sent by the client for encrypted requests, if there was any. See the "Identifying clients" section of our wiki.

New "dnscrypt" "client_proto" value in GET /querylog response

• The field "client_proto" can now have the value "dnscrypt" when the request was sent over a DNSCrypt connection.

New "reason" in GET /filtering/check_host and GET /querylog

• The new RewriteRule reason is added to GET /filtering/check_host and GET /querylog.

• Also, the reason which was incorrectly documented as "ReasonRewrite" is now correctly documented as "Rewrite", and the previously undocumented "RewriteEtcHosts" is now documented as well.

Multiple matched rules in GET /filtering/check_host and GET /querylog

• The properties rule and filter_id are now deprecated. API users should inspect the newly-added rules object array instead. For most rules, it's either empty or contains one object, which contains the same things as the old two properties did, but under more correct names:

  {
    // …
  
    // Deprecated.
    "rule": "||example.com^",
    // Deprecated.
    "filter_id": 42,
    // Newly-added.
    "rules": [{
      "text": "||example.com^",
      "filter_list_id": 42
    }]
  }
  

  For $dnsrewrite rules, they contain all rules that contributed to the result. For example, if you have the following filtering rules:

  ||example.com^$dnsrewrite=127.0.0.1
  ||example.com^$dnsrewrite=127.0.0.2
  

  The "rules" will be something like:

  {
    // …
  
    "rules": [{
      "text": "||example.com^$dnsrewrite=127.0.0.1",
      "filter_list_id": 0
    }, {
      "text": "||example.com^$dnsrewrite=127.0.0.2",
      "filter_list_id": 0
    }]
  }
  

  The old fields will be removed in v0.106.0.

As well as other documentation fixes.
