Connection defines between which connectors do we want to do requests, what kind of requests and specify mapping between them. This is a core element of the application. The list of connections displays only a title.


Adding/updating connection consist of three steps: direction, mode, and methods. There is an explanation tour for creating connection. The direction page has two fields: title and connectors.They are both required. The title must be unique, it is checking before going to the next page. The connectors are two: from connector and to connector.


The mode step has one required field - mode. It can be expert or template. If template is chosen, their will be appeared a select field, where you can select a template that you need or you cat delete it.


if you come back to this step from the next step, choosing another mode will affect on the adding, that is why you need to confirm your choice.

The methods step has two areas: methods and mapping fields. There is also a possibility to add this connection to the templates. Clicking on the image3 button appears a window where should be provided a name.

The methods area is divided into two parts: left and right. On the left side you see elements belongs to from connector and on the right to to connector.

Method represents the request to the connector with defined parameters. There are two types of elements: method and operator. Clicking on the image4 button you can create the element. The element will be located after the current element, that is pointed with an arrow image5. Each method has his own color that generates automatically. To remove the method just click on the recycle icon.

The method consists of Query and Body.


Query is a URL that can be modified during the request. It has a prefix, that is defined in invoker xml file. Mouseover here


you can see it. Clicking on this icon popped up an input to modify the query.


There is a possibility to add a parameter into the Query (except the first method in from connector). This parameter is a reference to the response of the previously created method.

If the response is in json format and array, then you can choose the whole array or only a specific element in the array typing [arrayIndex]. It means to take the element with the specified index. To choose the whole array you need to type [*].


If the response is in xml format then you can also reference to the attribute of the xml tag. Just type @ and if the xml tag has attributes they will be popped up and you can select one.


You choose method, fill out the parameter and click plus button. The parameter comes from the invoker. If it exists there, you will see it after typing the third symbol in the input field as a select popup block.

Body has an icon image10. Clicking on it popup a block of request that you send using this method. It can be modified using image11 icon or directly change each parameter. There is also a possibility here to add a parameter from the response of the previous methods. Type # as the first character and you will see another popup image12. You can handle with that in the same principe as for the Query. When you finish with editing click on the apply icon image13.

When you create an operator there are two options: if and loop. if operator does a condition before performance. You should define here also a reference, choose a condition operation and set with what are you doing to compare.


loop operator makes request in the loop under conditions that you define.


As you can mention, all items under the operators are shifted on the right to see the scope of their influence. There can be a lot of items, that means can be shifted quite well on the right. We have limited the overview and brought history here. Both from connector and to connector can have 5 elements. If you have more than five, appears a navigator on the left side with progress bar image16. Clicking up or down you can navigate throw the elements and see how deep you are, just looking on the progress bar. Moreover, there is a history on the top image17. This history displays you all operators that are participating to fulfill the current item. Clicking on the search icon image18 you see the whole structure of the connector.


Press arrows up and down to navigate there or left and right arrows to minimize or maximize accordingly the operators. Clicking on the item here you go directly to that element and it will selected as the current one.

Mapping Fields displays the relationship between the fields of the methods.


They are created immediately after setting references in Body. The relationship can be one to one or many to one. Moreover, you can add an enhancement between fields. Clicking on the enhancement title you will see a popup window where you set a description and an enhancement itself.


There are predefined variables to relate with the fields. VAR_[i] are coming parameters and RESULT_VAR is the final value for to connector field.

Documentation about APIs of the connectors are available on this page. Clicking on the icon image22 you will see the appropriate documentation.


There are method and title of the request. If you want to read the specific request in details just toggle it clicking on the title.


Moreover, you can test the request clicking on image25. Then you see a popup window where you already have predefined method, request and body.


You can change the method, add headers or update body. To add a header type his key and value. After click on the image27 icon. If you have more than two headers just click on image28 and image29 arrows to navigate between them. After you prepared the request, press Send button and the response will appear in the Response tab.
