You can create a Resolve Approval Request action that allows your flows to approve, reject or remove Salesforce approval processes. The action looks like this:
|action||Supported values: Approve, Reject, and Removed (See this for more info).|
|approvalRequestId||This can be extracted from email notifications. See this.|
|comments||Text provided here will be saved in Approval Activity History|
|nextApproverIds||(See this for more info).|
Instead of installing a package, you’ll need to copy this apex code and add it to your org as a new Apex class ( It’s not currently possible to package actions that use Approval Process apis.) You can create the class using Developer Console or Setup -> Custom Code -> Apex Classes. After creating the action, you can create a flow like this:
In the example flow above, the first action is the Find Text action . It’s used in this specific example to extract the id of the approval process from an email notification. In other use cases, you’ll be able to get the approval process id in other ways.
This action is used to work around a bug in Approval Processes.
