Login to Developer Portal
To create a workflow, log in to your Filestack account with your email and password. Inside the Dev Portal, you’ll see a menu running down the left-hand side of the page. Click on “Workflows”, and you’ll be taken to the Workflows List Page.
Create New Workflow
On the Workflows List Page, click the orange ‘Create New’ button to create a new Workflow.
Name your new Workflow, then click the orange circle with the + icon to begin selecting your first ‘Task’ – a step in your Workflow that will evaluate and/or transform your incoming files when they are received.
Configure tasks
From the Task Panel, select any task. In this example, we’ve selected “filetype” so we can begin this Workflow by detecting what type of file is being received.
OPTIONAL: Name the Task. REQUIREMENT: The Task name must be unique. It’s OK to leave the default, random value as the Task Name if desired.
Click the orange ‘Save’ button in the Task Panel (both Workflow & Task will be saved).
Continue to build out your Workflow by selecting the second task. Apply any logic conditions desired. In this example, we want to determine whether an uploaded file is of the type JPEG or PNG. Insert an anchor point, and cropping dimensions. For condition, path = mimetype, to determine type. Add condition/Value.
Save Task, will save workflow.
Create new branch, for PNG files.
Store JPEG based on the condition.
Save Task, will Save Workflow.
Select new task, in this example, the Black and White filter (100% Threshold will return an entirely black image, so for that particular transformation, start with a mid-range value like 50% and test your results for a proper aesthetic balance!), for PNG images:
Save
Select new task to store BW-converted PNG’s
Save
