Service Connector Bindings

Service Connector Bindings

For each action in a service connector, the Binding options enable you to specify the interface and parameters required to communicate with a service.

Binding Properties

Specify values for these options:
  • URL
    : Enter the URL of the REST Service.
  • Verb
    : Choose how to send data to the service:
    • GET
      , and
      : Process Designer automatically generates the query parameters.
    • PATCH
      , and
      : Process Designer adds a Binding Type field from which you can then choose JSON, Form, URL, or Custom. If you choose Custom, a Body field appears where you can type the information that is sent to the service. Consult the API documentation to determine what you should enter.
  • Multi Using
    : This option determines how query string parameters are generated when you need to specify multiple values for a parameter. Choose one of the following:
    • Semicolon separated
      : for a semicolon-separated multi-select list, Process Designer adds input parameter values as a single string. (For example,
      ). This is the default.
    • Comma separated
      : for a comma-separated multi-select list, Process Designer adds input parameter values as a single string. For example,
    • Append brackets
      : for a semicolon-separated multi-select list, Process Designer maps semicolon-separated values to multiple query parameters of the same name, and appends [] to the parameter name. For example,
    • Append numbers
      : for a semi-colon separated multi-select list, Process Designer maps semicolon-separated values to multiple query parameters of the same name and adds a number to the end of the field name, that is, 1..N. For example,
  • Authentication
    : You have two options to define the authentication information that the service requires: Basic or Custom. If you choose:
    • Basic
      , enter the user name and password, if required.
      Enter text or an XQuery expression in the user name and password fields. If you enter an XQuery expression, you can pass the password value through a connection instead of hard coding it in the service connector.
      Show password
      to see the value of the password on screen. When you export the service connector with
      Show password
      selected, you also export the password.
    • Custom
      , add the security parameters based on the service requirements. For example, you might need to send signed data using an HTTP header.

Other Parameters

Use this section to add input parameters required by the service. The value may be specified as a literal or expression. Refer to documentation from the service you are using.
To add a row and enter multiple parameters, click the
sign. To remove a row, click the
For each row, enter:
  • Name
    : the name of the parameter as specified within the service being called.
  • Content
    : the value to specify for the parameter, if any.
Show Advanced
to select these optional parameters for the Binding:
  • Sign With
    : The value that is computed will first be signed using SHA1, and the result of the signature will be this value.
  • Sign Using
    : Choose to sign the field using SHA1 or SHA256.
  • Encode Using
    : Choose to encode the field as Base64 and Hex64Upper.
  • Temp
    : If checked, Process Designer will not generate a parameter when using GET or POST. For more information, see the Parameters described here: Input Tab.
  • Attachment Base64
    : The base64 encoding of the attachment associated with the <inputName>.
  • Attachment Name From
    : The file name of the attachment associated with the <inputName>.
Hide Advanced
to hide the fields.

HTTP Headers

If the service requires one or more HTTP headers, enter the Name and Content (value of the parameter) for each header in this section.
To define a SOAP-based service connection, you must add both the "SOAPAction" and "Content-Type" headers. The value of SOAPAction can be empty, dynamically set using GET, or defined in the WSDL.
If the service does not set the content-type in the response header, the service connector attempts to infer the content type from the payload. For example, if the response starts and ends with either "{...}" or "[...]", the response is parsed as JSON. If the response payload starts with an angle bracket ("<"), it is treated as XML. If the response payload cannot be parsed due to malformed JSON or XML, it is processed as a regular string.
If the response Content-Type header contains the term
in the first part and the term
in a subsequent part, Application Integration infers the response payload type as JSON. Similarly, if the response Content-Type header has the term
in the first part and the term
in a subsequent part, Application Integration infers the payload type as XML.
As you type in the Name field, Process Designer displays commonly used values, including:
  • Accept
  • Accept-Charset
  • Accept-Encoding
  • Accept-Language
  • Content-Type
  • SOAPAction
Some services request an MD5 signature. You can generate an MD5 signature in the
HTTP Headers
section of service connector actions.
To generate an MD5 signature, perform the following steps:
  • Enter a name for the HTTP header. For example, enter
  • Go to
    Formula Editor
  • Under
    , select
  • Under
    Insert Field
    , select
When you test or run the service connector, the used variable contains an MD5 checksum for the generated request payload.

Content Type and Character Sets

You can determine the charset used for a request payload as noted here:
  • Specify a charset value in the Content-Type header. In this case, the header determines the charset of the request payload. In this case, the charset is based on the value specified in the header unless the request format is an attachment type, in which case each part of a multipart/form-data request will be treated separately. If you set the Content-Type and want the service connector to append the default charset automatically, add a semi-colon after the specified Content-Type, as shown here:
  • Do not specify a charset value in the Content-Type header so this value can be set automatically based on the request format. To ensure that the content can be decoded correctly, the service connector appends the default charset (UTF-8) to the Content-Type. For example, the value might be set as follows:

Editor for Service Connector Properties

To define the binding parameters, you can use the
Editor accessible for the URL, Other Parameters, and HTTP Headers fields.
To open the
Editor, click
next to the field you want to edit. When it opens, the
Editor gives you access to a list of available functions and the fields defined for the service connector, as shown in this image:
Based on the type selected for the expression, the
Editor applies syntax validation. In this case, the post_url field is validated as an XQuery variable.
For more information, see Using the Expression Editor.
