Setting up Communication Channels

Creating a Channel

A channel forms the basis of communication in webMethods.io B2B. It encompasses a variety of underlying protocols such as HTTP, AS2, and so on to facilitate document exchange. All transactions among partners therefore leverage the underlying transport and exchange capabilities of channels.

To add a channel

  1. In webMethods.io B2B, go to Communication icon > Channels.

  2. Click Add Channel and select a channel type.

    • Inbound Channel
    • Outbound Channel
  3. Provide a name that identifies the channel.

  4. Select the channel type and type a description for the channel.

  5. Specify the connection details for the channel depending on the type. The following table lists the supported channel types and behavior:
    See Supported Channel Types and Details for the list of all supported channels.

  6. Enable the Partner-specific channel option to associate only a single partner per channel.
    webMethods.io B2B recognizes the sender in the business document without reading the payload that is shared in the business document.
    If the receiver details are not available, then the enterprise is considered as the receiver.

    Note: If the sender information is not available in the payload, and the document is submitted using partner-specific channel, then the sender information is retrieved using the channel-partner association.

    If the receiver information is not available in the payload, and the document is submitted using partner-specific channel, then the enterprise is considered as the receiver.

  7. Switch icon to disable the channel.
    A channel is enabled by default except for SFTP-IN-CLIENT. By default, SFTP-IN-CLIENT channel is disabled.

You cannot update channel properties without deactivating the channel.

Important: Disabling a channel disrupts the communication for all the partners associated with the channel.

If you have to troubleshoot, see here

Custom Domain

webMethods.io B2B provides support for customer-specific domains for branding purposes. This capability allows your tenant URLs to appear as ‘.mycompany.com’ instead of ‘.gateway.webmethods.io’. Contact Software AG Support if you have such a need.
Also, this requires additional steps to be configured for the paid tenants along with customer-certificates. Due to the nature of the functionality, you may notice some limitations, and certain use-cases may be impacted. For more information, see the documentation on webMethods.io Integration.

Viewing Channels

Channels created in webMethods.io B2B are listed in the Channels page.

To view channels

  1. In webMethods.io B2B, go to Communication icon > Channels.

  2. Click the channel name you created to view its details.
    The following table lists the details of a channel:

    Field Description
    Name Name of the channel that you created.
    Type Type of channel.
    - Inbound. A method for receiving a document from a partner.
    - Outbound. A method for sending a document to a partner.
    Description Description you typed to indicate the purpose of the channel.
    Status Status of the channel. The possible statuses are:
    - Active
    - Inactive
    Actions Perform actions such as delete and edit.

Sharing Inbound Channel Endpoint Details

You can share the inbound channel endpoint details with your business partners to receive documents from them.

To share channel endpoint details

  1. In webMethods.io B2B, go to Communication icon > Channels.

  2. On the Channels page, click a channel name to view its endpoint details.

  3. Share the endpoint details with your business partner along with the associated partner user credentials using an email.
    A partner can use any HTTP client to send a business document to the endpoint URL. The email must contain information about how the partner can use the endpoint URL to send documents:

    a. Select the HTTP POST method.

    b. Specify the HTTP request URL as the given endpoint URL.

    c. Set the authorization to basic and specify the username and password configured as the partner user credentials. For more information, see Adding a Partner User.

    d. Set content-type header as application/edi and the content of the document in the request body.

    e. Send or submit the request.

In case a partner wants to send a document, the following headers must be included:

Note: Ensure that the message-ID is unique, else the message is considered a duplicate and subsequently ignored.

Mapping the RNIF-OUT Channel with a Partner

To associate a partner with an outbound channel, see Associating or Mapping outbound Channels with a Partner.

SFTP-IN-CLIENT

Important: The SFTP-IN-CLIENT channel is for inbound documents that are meant for typical B2B payloads which are not very large. Software AG recommends that you use this channel type for documents lesser than or equal to 1 MB. If the document size is larger, then it may take longer to process and may time out in certain cases depending on the various network, client, or server settings of the trading partner. Also note that a maximum batch of 3 inbound business documents can be processed by one SFTP-IN-CLIENT channel.

An SFTP IN Client channel details:

Field Description
Connection
Hostname Host name or IP address of the partner’s SFTP server. For example, trader.com.
Port An active port on the partner’s SFTP server. For example, 3456. Default is 22.
If the port to which the connection is being established is either invalid or not open, it results in a bad gateway error.
Host public key option Public key used to establish a secure connection with partner’s SFTP server. Select from the following options:
  • Auto retrieve - webMethods.io B2B automatically retrieves the public key file.
    Note: Ensure that the hostname and port are active and accessible.
  • Upload - You can upload the public key file.
Username Username used to connect to partner’s SFTP server.
Authentication type Type of authentication required to connect to partner’s SFTP server. Select from the following types of authentication:
  • Password
  • Public key
Password If you selected Password as the authentication type, provide the password to connect to partner’s SFTP server.
Private key If you selected Public key as the authentication type, upload the private key file required to connect to the partner’s SFTP server.
Passphrase If you selected Public key as the authentication type, provide the passphrase used to protect the private key.
Polling
Folder path The path to the folder that contains the files to be exchanged. For example: docs/por. webMethods.io B2B polls this folder to fetch the files. It polls only the specified folder and not any other folder or sub folders.
In case that a post processing action fails for a file, the file continues to exist in this location and will be picked up during the next polling interval.
webMethods.io B2B is designed for one-to-one mapping between SFTP-IN-CLIENT channel and SFTP server source folder. Therefore, while creating the SFTP-IN-CLIENT channel, you must create one SFTP-IN-CLIENT channel per SFTP server source folder. If you create multiple SFTP-IN-CLIENT channels for the same SFTP server source folder then there is a chance that the same file may be processed multiple times by webMethods.io B2B.
Note: If there are multiple files, then the order of fetching the files depends on the file system settings of the SFTP server. For example, webMethods.io B2B may fetch the files added first to the folder or in an alphabetical order based on the SFTP server settings.
File name filter Filter criteria used to identify the specific files for polling. You can provide a comma separated list of filter criteria. For example, *.xml, *.txt, test_*b2b*123*.
Type of document The channel’s document type used to process files. Select from the following document types:
  • EDI
  • XML
  • Other
Note: You can only create one channel per document type.
Frequency Frequency at which webMethods.io B2B polls the partner’s SFTP server for new files. Specify a numeric value. Default value is 5.
Unit of frequency Unit of frequency specified in Frequency. Select from the following units:
  • Minutes
  • Hours
  • Days
Default value is 5. This makes the default polling frequency to be 5 minutes.
Post processing
Action Action to be taken by webMethods.io B2B on the files after processing them. Select one of the following actions:
  • Move to folder
  • Delete
Default is Move to folder.
Folder path Path of the folder to which webMethods.io B2B places the files after processing. By default, webMethods.io B2B appends/processedto the folder path that you specified earlier in the Polling segment. For example, docs/por/processed.
Important: Ensure that the folder you specified has sufficient permissions for webMethods.io B2B to access and place the processed files.
In certain cases, the SFTP server might not support operations such as a file overwrite or rename. This might result in failure of the post processing action because of the inherent limitations of the underlying SFTP server. Refer to the SFTP server documentation to learn more about such limitations.
Note: If webMethods.io B2B fails to move the files to the folder that you specified in this field, then webMethods.io B2B places the files at the default location. In this example at docs/por/processed.
Allow folder creation If the folder specified in the Folder path does not exist, enable this option to allow webMethods.io B2B to create a new folder with the same folder name.
webMethods.io B2B does not support creation of nested folders in SFTP server. For example, if docs/por is the existing folder path, then docs/por/processed is supported, whereas docs/por/processed/partners is not supported.
Note: If specified the folder is inaccessible or if you fail to enable the Allow folder creation option, then webMethods.io B2B places the files at the default location. In this example at docs/por/processed.

You can configure the settings required to identify the Flat File inbound documents you receive though SFTP-IN channel. The settings are listed as follows:

Field Description
Key Specify a valid key to identify the Flat File document type. For example, a filename
Value Specify the corresponding value for the Key that was defined. For example, sample.txt.

Points to note
A short delay may be observed while exchanging files from source folder to the target folder.
The delay can be mainly observed due to the following reasons:

Mapping the SFTP-IN Channel with a Partner

An SFTP-IN channel connects with an external SFTP server to poll for inbound documents in a pre-configured location on the SFTP server. Therefore, you do not need to create a partner user and use its credentials to send documents to an SFTP-IN channel. Upon creating an SFTP-IN channel, you must provide the SFTP server credentials so that webMethods.io B2B can poll the SFTP server location at regular intervals.

SFTP-OUT-CLIENT

As SFTP is an SSH-based protocol, TLS v1.3 is not supported for SFTP outbound communication.
An SFTP OUT Client channel details:

Field Description
Connection
Hostname Host name or IP address of the partner’s SFTP server. For example, trader.com.
Port An active port on the partner’s SFTP server. For example, 3456. Default is 22.
If the port to which the connection is being established is either invalid or not open, it results in a bad gateway error.
Host public key option Public key used to establish a secure connection with partner’s SFTP server. Select from the following options:
  • Auto retrieve - webMethods.io B2B automatically retrieves the public key file.
    Note: Ensure that the hostname and port are active and accessible.
  • Upload - You can upload the public key file.
Username Username used to connect to partner’s SFTP server.
Authentication type Type of authentication required to connect to partner’s SFTP server. Select from the following types of authentication:
  • Password
  • Public key
Password If you selected Password as the authentication type, provide the password to connect to partner’s SFTP server.
Private key If you selected Public key as the authentication type, upload the private key file required to connect to the partner’s SFTP server.
Passphrase If you selected Public key as the authentication type, provide the passphrase used to protect the private key.
Password If you selected Password as the authentication type, provide the password to connect to partner’s SFTP server.
Private key If you selected Public key as the authentication type, upload the private key file required to connect to the partner’s SFTP server.
Passphrase If you selected Public key as the authentication type, provide the passphrase used to protect the private key.
Destination details
Folder path The path of the folder into which webMethods.io B2B places the files.
Allow folder creation If the folder specified in the Folder path does not exist, enable this option to allow webMethods.io B2B to create a new folder with the same folder name.
webMethods.io B2B does not support creation of nested folders in SFTP server. For example, if docs/por is the existing folder path, then docs/por/processed is supported, whereas docs/por/processed/partners is not supported.
File name prefix Prefix to add to the file name. Default value is wmiob2b. webMethods.io B2B constructs the file name by combining the prefix and timestamp. Thus, the file name format is: prefix\_<current\_timestamp in YYYYMMDDhhmmssSSS format\>. For example, wmiob2b_20200623062905325.
Document delivery rate
Enable Allows you to limit the rate at which documents must be delivered to the endpoint. You must persist the document in the database so this option can be used to deliver documents in a regulated manner.
Maximum number of requests per minute Specify the maximum number of business documents that can be delivered to the outbound channel endpoint. You can tune this rate based on the performance of the partner systems that receive the business documents on this endpoint. The default value is 1 (minimum). The maximum value is 1000.
