To install the PEGA, you need to: [Import a connector to the Pega server](#import) [Create a library](#lib) [Create required functions](#func) ## Importing a connector to the Pega server To import the connector to the server: 1. Open **Dev Studio** and click **Configure → Application → Distribution → Import**. Screenshot of Pega Dev Studio with the Configure menu open, showing the Application → Distribution → Import path being selected to import the connector.

## Creating a library To create a library: 1. Click **Records → Technical → Library → Create**. 2. In the **Label** field of the **Create Library** tab, specify a name for the library (e.g. *ABBYY*) and fill in the **Identifier** field. Make sure that the library is being created within the context of your application and then click **Create and open**.

3. On the **Packages** tab, add the following packages: * *java.util.*\* * *java.nio.file.*\* * *java.net.*\* * *java.lang.*\* * *java.util.stream.*\* * *org.apache.commons.lang3.*\* * *abbyy.flexicapture.webapi.client.*\* * *abbyy.flexicapture.webapi.client.api.*\* * *abbyy.flexicapture.webapi.client.models.*\* Screenshot of Pega Dev Studio on the library Packages tab, listing the nine Java packages to include, including the abbyy.flexicapture.webapi.client packages, with the Generate Library button below.

4. On the **Static Variables** tab, create the following string variables: * *baseUri* * *tenantName* * *userName* * *Password* * *multiFileProjectName* * *singleFileProjectName* Screenshot of Pega Dev Studio on the library Static Variables tab, showing the baseUri, tenantName, userName, password, multiFileProjectName, and singleFileProjectName String variables and their sample values.

5. Click **Save** and then click **Generate Library**. ## Creating a function A function contains Java code that is executed when the function is called from other Pega objects. The input and output parameters of a function are specified on the **Parameters** tab, while exceptions are specified on the **Imports & Exceptions** tab. To create a function: 1. Click **Records → Technical → Function → Create** and fill in the **Label** and **Identifier** fields. 2. In the **Library** field, specify the name of the library you created earlier. 3. In the **Parameters** section, specify the following two input parameters: | **Name** | **Java type** | | --------------- | ------------- | | *FileName* | *String* | | *Base64Content* | *String* | 4. Make sure that the function is being created within the context of your application and click **Create and open**.

5. In the window that opens, on the **Parameters** tab, specify *int*, *string* or *boolean* as the data type in the **Java data type** field: Screenshot of Pega Dev Studio on the function Parameters tab, showing the fileName and base64Content String input parameters and int entered as the Java data type in the Output section.

7. Go back to the **Java** tab, insert the code for the function in the **Java source** field, select the **Function ready to be compiled?** option, save your changes, and click **Generate function**. The code for the function can be copied from the java file, which you can find in *%Installation Path%\Connector for FlexiCapture as a Service with verification\Samples\Code examples\Pega Functions*.
