DocuSign Connector 1.0 Examples - Mule 4

This example shows how to create a DocuSign envelope. The example contains two flows:

The first flow provides a template for a user interface.
The second flow creates the DocuSign envelope.

Before You Begin

You must have:

Anypoint Studio
Mule runtime engine (Mule) 4.2.1 or later

Create the First Flow

The first flow provides a template for the user interface. To change the template used in the flow, select the Parse Template component and go to the Location field to update the location with the path of the desired template.

In this flow, you configure:

An HTTP Listener component
A Parse Template component

Configure HTTP Listener

Configure HTTP Listener to initiate a Mule flow when a call is made to the / account path on localhost, port 8081.

This example uses variables for some field values. You can either:

Replace the variables with their values in the code.
Provide the values for each variable in a properties file and then refer to that file from the connector configuration.

If you don’t know how to use a properties file, see Configuring Property Placeholders.

To configure HTTP Listener:

Create a new Mule project in Studio.
In the Mule Palette view, search for http and select the Listener operation:
Drag the Listener operation onto the canvas.
In the Listener configuration, click the Add icon next to the Connector configuration field to add a global element.
Click OK to accept the defaults.
Set the Path field to /.

Add the Parse Template Component

The Parse Template component creates a template for an HTML form (form.html), which is located in the main resources folder. The example uses this form to convey information for creating an envelope.

From the Mule Palette view, search for parse and drag Core> Parse Template onto the canvas, next to HTTP Listener.
Configure the following fields in the Publish properties window:

Field Value

Display Name

Name for the component, such as Parse Template.

Location

Location of the file, such as form.html.

Field	Value
Display Name	Name for the component, such as `Parse Template`.
Location	Location of the file, such as `form.html`.

Create the Second Flow

The second flow creates the DocuSign envelope. The status, emailSubject, documents, and recipients (combined URI and recipient URI) parameters must be provided.

DocuSign Connector Second Flow in Studio

In this flow, you configure:

An HTTP Listener component
Logger component
Envelopes Post Envelopes operation
Transform Message component
A second Logger component

Configure HTTP Listener

Configure HTTP Listener to initiate a Mule flow when a call is made to the / account path on localhost, port 8081.

This example uses variables for some field values. You can either:

Replace the variables with their values in the code.
Provide the values for each variable in a properties file and then refer to that file from the connector configuration.

If you don’t know how to use a properties file, see Configuring Property Placeholders.

To configure HTTP Listener:

Create a new Mule project in Studio.
In the Mule Palette view, search for http and select the Listener operation:
Drag the Listener operation onto the canvas.
In the Listener configuration, click the Add icon next to the Connector configuration field to add a global element.
Click OK to accept the defaults.
Set the Path field to /create-envelope.

Add a Logger Component

Configure a Logger component to perform logging on the payload.

In the Mule Palette view, search for logger.
Drag the Logger component onto the canvas, next to HTTP Listener.
Configure the following fields:

Field Value

Display Name

Name for the logger, such as Payload Passed To The Operation Logger.

Message

Enter #[payload].

Level

INFO (Default).

Field	Value
Display Name	Name for the logger, such as `Payload Passed To The Operation Logger`.
Message	Enter `#[payload]`.
Level	INFO (Default).

Add the Envelopes Post Envelopes Operation

The Envelopes Post Envelopes operation creates an envelope from the template.

Drag the Envelopes Post Envelopes operation onto the canvas, next to Logger.
In the Envelopes Post Envelopes configuration, click the Connector configuration dropdown and select Docusign_Connector_Config.
Configure the following fields in the Envelopes Post Envelopes properties window:

Field Value

Account Id

${account.id}.

Body

payload.

Field	Value
Account Id	`${account.id}`.
Body	`payload`.

Add the Transform Message Component

The Transform Message component converts the input data from the template.

In the Mule Palette view, search for transform message.
Drag the Transform Message component onto the canvas, next to Envelopes Post Envelopes.
In the Transform Message configuration, overlay the brackets in the Output section with this XML:
```
%dw 2.0
output application/json
---
payload
```

Add the Second Logger Component

Configure a second Logger component to perform logging on the output of the Transform Message component.

In the Mule Palette view, search for logger.
Drag the Logger component onto the canvas, next to Transform Message.
Configure the following fields:

Field Value

Display Name

Name for the logger, such as Logger.

Message

Enter #[payload].

Level

INFO (Default).

Field	Value
Display Name	Name for the logger, such as `Logger`.
Message	Enter `#[payload]`.
Level	INFO (Default).
