Changes in This Release

This release contains the following changes:

This connector no longer has the Upload File operation because the Slack files.upload API method is deprecated. For more information, refer to the Slack API documentation.
To upload files, this connector now includes the new Get upload url and Complete Upload External operations.

For more information about the operations, refer to Get Upload URL and Complete Upload External.

For examples about how to use these operations, refer to Upload a File to a Slack Channel (Using File Path) and Upload File Text Content to a Slack Channel.
In the Slack Connector configuration window, the TLS tab is renamed to the Security tab.

Upgrade Prerequisites

Before you perform the upgrade, create a backup of your files, data, and configurations in case you need to restore to them.

Upgrade Steps

Follow these steps to perform the upgrade:

In Anypoint Studio, create a Mule project.
In Mule Palette, click Search in Exchange.
In Add Dependencies to Project, enter slack in the search field.
In Available modules, select Slack and click Add.
Click Finish.
Verify that the Slack Connector dependency version is 2.x in the pom.xml file in the Mule project.

Studio upgrades the connector automatically.

Verify the Upgrade

After you install the latest version of the connector, verify the upgrade:

In Studio, verify that there are no errors in the Problems or Console views.
Verify that there are no problems in the project pom.xml file.
Test the connection to verify that the operations work.

If it is necessary to revert to the previous version of Slack Connector, change the mule-slack dependency version in the project’s pom.xml file to the previous version.

You must update the project’s pom.xml file in Anypoint Studio.
