Router

Router module allows you to branch your flow into several routes and process the data within each route differently. Once a Router receives a bundle, it forwards it to each connected route in the order the routes were attached to the Router. Routes are executed sequentially (not in parallel): a bundle is not sent to the next route until it has been completely processed by the previous route.

HINT: To verify the order, you can click the Auto-align icon, which will arrange the routes according to the order from top to bottom.

HINT: To change the order, just remove the Router module and re-connect the routes in the desired order. 

To filter bundles that will pass through to a specific route, define a filter. For more information on how to use filters, please refer to the help section on Filtering.

Default route

The route with ticked checkbox Default route is used in the case when a bundle could not continue on from the Router via any other route, since conditions specified in the filters for the other routes were not met. The Default route is distinguished with a different arrow sign inside the Router module:

Adding a Router to a scenario

A Router can be added to a scenario in one of the following ways:

1. Click on the right handle of the module where the Router shall be inserted and from the list of options that appear, choose "Router".
2. Click the wrench icon below a line connecting the modules in which you want to add a Router to and from the panel that appears, select "Add a router".
3. Click the left handle of a separate module and drag it towards a module, which on both sides is connected to other modules. This will insert a Router right after the connected module and connect the separate module to the scenario.

Example: Connecting Instagram to Dropbox and YouTube

The below scenario shows how to:

1. Download images from Instagram, resize them and upload them to a Dropbox folder
2. At the same time, download videos from Instagram and upload them to YouTube

Instagram can return both images and videos. Adding a Router will allow you to divide the scenario and add a new route so that each type of bundle can be processed separately, at the same time.

Converger

Converger is a counterpart of the Router module. It enables you to merge several routes into one:
