- Amazon SNS Adapter
  With the Amazon SNS adapter, a user can access the Amazon Simple Notification Services. This adapter connects to the Simple Notification Services (SNS) topics, using AWS keys. The adapter can fetch and send notifications from and to those AWS SNS topics, to which the user has subscribed.
- Batch File and Shell Script Adapters
  The Batch File adapter processes a (Windows™) batch file as the data source of an input map card or the data target of an output map card. The Shell Script adapter processes a (UNIX™) shell script as the data source of an input map card or the data target of an output map card.
- CICS Adapter
  The Customer Information Control System (CICS) adapter allows you to retrieve CICS screen data without the difficulties associated with 3270 "screen scraping."
- Cipher Adapter
  The Cipher adapter encrypts and decrypts data by using the Advanced Encryption Standard (AES) established by the U.S. National Institute of Standards and Technology (NIST). A single cryptographic key enciphers (encrypts) and deciphers data. The cryptographic key is stored in a master key file (MKF) in an AES-based encrypted format. As long as the MKF is not compromised or lost, the enciphered data is cryptographically secure.
- Email Adapters
  An email adapter automatically receives email messages as sources of a map or sends email messages as targets of a map.
- FTP Adapter
  Use the File Transfer Protocol (FTP) Adapter to transport data. When source data arrives at its target, it often must be transformed into a different format for a receiving application to use it successfully.
- Excel Adapter
  The Excel Adapter reads data from and maps data to a sheet in a Microsoft Excel workbook.

- IBM MQ Adapter
  The IBM® MQ adapter works with IBM MQ to accomplish the task of maintaining data compatibility, handling all kinds of data transformations from the simplest to the most complex.
- Java Class Adapter
  Use the Java Class Adapter to instantiate a Java™ object and to invoke a sequence of methods on the object.
- HL7 MLLP Adapter
  The HL7 MLLP adapter uses the MLLP protocol over TCP/IP to pass data to and from HCL Link. The adapter has a listener interface that can detect the arrival of data on a socket and trigger a map to run. With the HL7 MLLP adapter, remote applications can pass data to HCL Link without using additional middleware software.
- Microsoft SQL Server Adapter
  This documentation discusses the Microsoft SQL Server Adapter. You can use the adapter with the Command Server, or with a map in a map rule.
- JAXB Adapter
  The JAXB adapter converts Java™ objects to XML and converts XML to Java objects. With the JAXB adapter, you can build Java objects that can be represented with XML, parse the objects, and use them in maps. The JAXB adapter supports all JAXB properties for marshalling and unmarshalling an XML document.
- JDBC Adapter
  Use the Java Database Connectivity (JDBC) adapter to query or update a database through the appropriate JDBC driver for the database.
- JMS Adapter
  Use the Java™ Message Service (JMS) Adapter as a client to any JMS-compliant messaging system provider.
- JNDI Adapter
  Use the Java™ Naming and Directory Interface (JNDI) Adapter to enable maps to look up, add, modify and delete entries in external directories, and retrieve the results that these operations return so that they can be reused in a map.
- MongoDB Adapter
  Use the MongoDB adapter to create, read, update, and delete single or multiple JavaScript Object Notation (JSON) documents in a MongoDB database.
- OData Adapter
  The OData (Open Data Protocol) adapter provides support for performing read and write operations on data sources that expose OData interface. OData adapter is an ISO/IEC approved, OASIS standard that defines a set of best practices for building and consuming RESTful APIs.
- OpenPGP Adapter
  Use the OpenPGP Adapter to exchange information with the GnuPG application.
- PDF Adapter

  - System requirements
    See the release notes for the PDF Adapter requirements.
  - PDF Adapter commands
    - Command aliases
      The PDF Adapter works with Acrobat forms and templates to generate a PDF document or extract data from all or part of an input PDF document.
    - Transaction scope and document persistence in memory
      When a document is added using the -ADOC command, the PDF Adapter stores the document in memory. Documents stored in memory are identified by a document identifier that is either provided by the user, or generated by the PDF Adapter. The document persists in memory as specified by the transaction scope in the card settings.
    - The data_from_map option
      Some of the PDF Adapter action commands that follow include the data_from_map option. The data_from_map option represents the data that is passed as the third parameter of a GET function. It is not a parameter on the adapter command line.
    - Add document (-ADOC) command
      The -ADOC command adds a file on the local file system, or a remote file, accessible through http protocol, on the file system as a document in memory and returns the document ID to the map. Alternatively, the -ADOC command can add dynamic data from a map as a document in memory and return the document ID to the map.
    - Remove document (-RDOC) command
      The -RDOC command removes a document from memory. By default, documents are removed from memory when a map, or card, processing completes. Transaction scope card setting determines the document persistence in memory. Use this command if too many intermediate documents accumulate in memory during map processing.
    - Replace document (-UDOC) command
      The -UDOC command replaces an existing document in memory with a new one and returns the new document ID.
    - Get document data (-GDOC) command
      The -GDOC command returns data from a document in memory.
    - Filename (-URL) command
    - Schema (-SCHEMA) command
    - Page (-PAGE) command
    - PDF Template (-TEMPLATE) command
    - Name lookup file (-NAMES) command
    - Append data (-APPEND) command
    - PDF transformation (-PDF) command
      The -PDF command allows the map to transform map data in XML format to PDF data using the GET map rule. PUT receives map data in XML format and transforms it to formatted PDF data. This command allows the same with GET, so that it can return PDF data back to the map, by performing in-memory transformation. The XML format data must conform to the PDF importer generated, native XML schema for the corresponding PDF document
- REST Adapter
  REST adapter is a solution where Link can readily call any Web/REST API and provide easy mapping to and from the APIs.
- Salesforce Adapter
  Salesforce Adapter provides support to access Salesforce REST API resource. It is useful for abstracting a piece of information or an action.
