Version 2023.06.1

Release Date: June 7, 2023 NEW FEATURE

• ​

  Manual Kubernetes Management

By default, definition and management of Gateway and Cache servers on Kubernetes was being done through Apinizer. With this version, the ability to manually manage existing Kubernetes clusters has been enabled by only making relevant metadata definitions. Thus, the requirement for Kubernetes environments to be managed through Apinizer management console has been made optional.

• ​

  Personal API Access Token Creation

Personal API Access Token is token information used to authenticate the user’s identity instead of password in the process of accessing Apinizer Management API. It is produced specifically for the user by the user logging into the management console.

• ​

  Restoring API Proxy According to Deployment History

API Proxy can be restored to its previous revision (deployed state) through API Proxy deployment history. IMPORTANT CHANGES AND IMPROVEMENTS

• User experience of date filtering fields in screens where job results are displayed has been improved.
• User experience of General Settings screen has been improved.
• With the save and update method added to ApiOps for API Proxy, registration addition if API Proxy does not exist, update if it exists has been enabled.
• In ApiOps API, in API Proxy save/update operations, if it exists in the request message, deployment after registration operation and ability to set routing information in settings operation have been enabled.

BUG FIXES APNZ-3434 : When Environment information is updated, pod statuses are not updated. APNZ-3602 : When API Proxy is deleted, all monitor information connected to it is deleted, but if there are scheduled jobs, they are not unscheduled. APNZ-3608 : When a request is made to API Proxy created with DB2API, error message for database connection does not appear correctly. APNZ-3636 : In the Routing tab on the API Proxy screen, if there are multiple Routing addresses, the first address is always written instead of the last address gone to in API Traffic logs.

​

Version 2023.05.1

Release Date: May 18, 2023 NEW FEATURE

• ​

  Defining SNMP Connection Configuration

SNMP connection definitions can be made to enable sending data to monitoring tools supporting SNMP protocol through Apinizer.

• ​

  Creating Action with SNMP

Sending data in actions created using SNMP Connection definitions to monitoring systems is enabled.

• ​

  Completely Disabling Elasticsearch Logging

Apinizer manages the logging process with Elasticsearch by default and performs all its queries on Elasticsearch for analytical operations on the Manager console. If desired, this feature can be disabled. When disabled, it should be noted that the analytics module, some policies, and monitoring features will be unavailable.

• ​

  Transferring Logs to Another System with Kafka Integration

By default, elements of messages coming to and going from API Proxy are stored on Elasticsearch. By making Kafka Integration, transfer of messages to a different application through the queue system can be performed.

• ​

  mTLS Authentication Policy

mTLS Authentication (Mutual Transport Layer Security Authentication) Policy is one of the authentication methods performed on the Apinizer side. This method is a type of TLS protocol used to create a secure channel between client and server. When mTLS Authentication is used, Apinizer checks the validity of the client’s certificate in incoming requests and ensures that a trusted certificate authority (CA) is used to ensure it comes from a specific certificate authority.

• ​

  Applying mTLS Setting to Request

mTLS configuration can be activated through Routing settings. Thus, the Apinizer client that will send from Apinizer to the target service verifies the target service’s certificate and indicates that it also has a certificate and needs to be verified by the target service. The target service also verifies the client’s certificate, and thus secure communication is established with the client.

• ​

  Applying mTLS Setting to Credential

If it is desired for the certificate to be verified with mTLS Authentication Policy of Credential, certificate upload for Credential can be performed.

• ​

  Log Settings Based on API Proxy Group

Settings can be made for whether message information coming to and going from API Proxies added to API Proxy Group will be logged in Elasticsearch database according to message elements (header, parameter, body) or transfer logs to a defined system (Syslog, Webhook, RabbitMQ, Kafka). IMPORTANT CHANGES AND IMPROVEMENTS

• For API Call policy’s cache feature to work, instead of whether there is a header named Cache-Control in the request coming to Api Proxy, it has been enabled to look at the header named Cache-Control at the moment the request arrives at API Call Policy in the request line.
• Export option has been added to the menu in screens where Global policies are listed.
• Definitions within Decryption, Encryption, and Digital Signing policies have been made editable.
• Information about which project it is in has been added to the list of API Proxy EKL and API Proxy Group EKL information.
• Creation of Query, Filter, and Report Generator based on application has been enabled.
• API Proxies and Overview screen in the Analytics menu (based on application) have been merged on the Overview page.
• Importing or Exporting IP Group Values
• Search filters according to Object name and Keyword information have been added to the Audit Records screen.
• Search operation in project dialog has been improved.
• Importing or Exporting Credential
• Importing or Exporting Database Connection Definitions
• Filtering options and table reading in the detail screen belonging to API Integration section have been improved.
• JOSE Validation and JOSE Implementation policies have been enabled to be added to both request and response lines.
• Authorization fields have been added inside JOSE Validation policy added to the request line.
• Warning icon has been enabled to come if a policy in API Proxy Group will not be applied to API proxy.
• Fields have been added to DB2API method creation settings to optimize when processing JSON data.
• Display of Keypair or Keypair Set information produced with JWK has been arranged clearly.
• Encryption algorithm of sensitive data stored in the database has been upgraded.
• A new option (Status Code List) has been added to the Error Handling Type feature in connection settings belonging to Routing.
• Management of log transfer for requests not coming to API Proxy in traffic log exports has been enabled from general settings.

BUG FIXES APNZ-3360 : When entering the detail of a record and returning on the Audit Records page, filters are cleared. APNZ-3365 : Problems are encountered when filtering is done according to advanced search fields on the API Proxy page. APNZ-3366 : Relative path information based on project is not added to imported API Proxy. APNZ-3386 : When the project’s General Settings page is clicked, the screen opens in a very long time. APNZ-3387 : On the Anomaly Detector screen, detail of the record with error cannot be accessed. APNZ-3304 : Snapshot Settings page contains screen errors. APNZ-3415 : When a log record is created for one of different API Proxies with a method containing ”/” within API Proxy Group, it is also displayed in the other API Proxy. APNZ-3417 : If uppercase is given to relative path value in API Proxy Group, path cannot be found. APNZ-3445 : When Apply by value in Cache tab of API Call policy is empty, the policy does not work. APNZ-3468 : Validation cannot be done with LDAP in JWT Policy. APNZ-3494 : Role information of Issuer cannot be retrieved when Authorization is enabled in JOSE Validation policy.

APNZ-3555 : Error is given when Decrypt By Issuer/Credential’s JWK option is active in JOSE Validation policy. APNZ-3584 : API Proxy cannot be created or updated from DB2API containing out parameter through MySQL connection. APNZ-3588 : Database connection configurations cannot be deleted. APNZ-3593 : Jobs belonging to Alert, Uptime Monitor, Anomaly Detector, and API Integrator cannot be listed on the Scheduled Jobs page.

​

Version 2023.03.1

Release Date: March 14, 2023 NEW FEATURE

• ​

  JSON Web Keypair Set (JWK) Creation

JWK holds public key or keypair information in JSON format. Keys, key sets, keypairs, or keypair sets can be created in 4 different types (RSA, EC, OCT, OKP) with 4 different methods (convert from key store, get from URL connection, paste from clipboard, generate). While these key definitions are used for validation or signing operations on message content in requests with JOSE policies, they are used for decryption or encryption of content in the response line.

• ​

  JOSE Validation Policy

JOSE (Javascript Object Signing and Encryption) is a solution used to facilitate secure transfer of “claim” or generally JSON data between any two parties. With JOSE Validation Policy, signature validation of signed data and decryption of encrypted data are performed.

• ​

  JOSE Implementation Policy

JOSE (Javascript Object Signing and Encryption) is a solution used to facilitate secure transfer of “claim” or generally JSON data between any two parties. With JOSE Implementation Policy, signing and encryption operations of data are performed.

• ​

  Elasticsearch Configuration

If logging is desired to be written to Elasticsearch by an external system rather than directly through Apinizer, Elasticsearch can be switched to read-only mode. In this case, writing of message logs coming to and going from API Proxy to Elasticsearch cluster is stopped on Apinizer and only reading logs is actively performed. Thus, query operations run by analytics screens continue.

• ​

  Transferring Logs with Webhook Integration

By default, elements of messages coming to and going from API Proxy are stored on Elasticsearch. By making Webhook Integration, logging of messages can be transferred to a different application.

• ​

  Transferring Logs to Another System with RabbitMQ Integration

By default, elements of messages coming to and going from API Proxy are stored on Elasticsearch. By making RabbitMQ Integration, transfer of messages to a different application through the queue system can be performed.

• ​

  Creating Alarm for System Information

In real-time systems, catching situations related to system resource usage before they turn into problems is an important requirement to prevent application performance from decreasing. Thus, solutions are produced for possible problems, preventing their occurrence. Alarm enables monitoring of Kubernetes modules and Elasticsearch clusters where the Apinizer Platform is located according to predefined trigger types. If the given threshold value is exceeded, a notification is created on the application.

• ​

  Creating a New Action Type: Notification

When creating Anomaly Detector, Uptime Monitor, API Integrator, or Alarm, a new action called notification creation action can be added to process the result at the end of the timer. Thus, whenever each job definition runs, notifications are sent to all users or users who want to receive notifications. Users can manage their notifications from the application’s interface.

• ​

  Managing Notifications

Notifications are created on Apinizer as a result of 3 different situations; notifications showing action results, Account/Developer creation requests, and API Product subscription requests. All notifications can be viewed from the icon in the application’s header section, and notification management can be done by clicking on the relevant notification category.

• ​

  Creating Connection Definition from MongoDB

MongoDB has been added as a new type to database connection configurations.

• ​

  Creating DB-2-API Find Method with MongoDB

When creating endpoints from database with Db-2-API in the API Creator module, endpoints can be added by writing find query with MongoDB configuration.

• ​

  Controlling All API Proxy Log Settings Based on Project or Application

Previously, settings were made on 3 different bases as Project, API Proxy Group, and API Proxy for which message elements’ log records would be taken in which region. To improve the usability and manageability of log settings, it has been reduced to only API Proxy basis. There are 3 different screens to enable or disable log settings; they can be set from each API Proxy’s own page, or multiple API Proxy log settings can be made through the Log Settings screen found based on Project and application.

• ​

  Defining Pod Probes from Kubernetes Resources Screen

Kubernetes uses Probes to know when containers will be restarted, ready, and started. Basically, Probes check the health of containers and ensure that unresponsive applications are restarted. Definition of Pods’ Probes has been enabled through Apinizer. IMPORTANT CHANGES AND IMPROVEMENTS

• User experience of appearance and action creation dialogs in Actions dialog has been improved.
• When API Proxy is created through Spec Design, it has been enabled to continue design from the created spec definition.
• Addition operation has been added to the original message data editing operation of body in API Call policy.

• IP information in Manager Console logins for Audit record has been enabled to be retrieved from X-Forwarded-For field.
• Control to add at least 2 addresses for Circuit Breaker to appear in API Proxy’s Routing tab has been removed.
• Fields for time information (Total Time, API Proxy Time, Backend Time) in Report Creation and Query screens have been revised.
• Connection configuration screens for databases have been merged.
• Log Settings tab has been added to API Proxy screen, separating all log settings from Settings tab.
• Management of Uptime Monitor and Anomaly Detector definitions based on application has been enabled.
• Required credentials to be entered in Database connections have been made optional to support connections that do not require credentials.
• Selection of password field in Plain-Text Authentication Policy has been made optional. Thus, services can be authorized using only API Key.
• In Authorization policy, only roles can be retrieved without performing role control.
• In JWT, OAuth2, and JOSE Validation policies, if Identity/Authorization Validation Service is selected, the ability to add roles in this service to the request header has been enabled.
• Sensitive Data Management, Syslog Integration screen has been moved to Log Settings menu.
• KPS Setting and ProCrypt screen have been moved to System Settings menu.
• API Proxy Report has been moved to Analytics menu.
• ACL Report screen has been moved to Identity Management menu. The screen that previously worked based on application has also been added to the project menu.
• API Proxies screen in Analytics menu has been removed, and table data here has been merged with table data in list mode of API Proxy Report screen.
