We investigated this question with our developer as well, and yes - it is doable even with our plugin. The main idea is that your API call needs to be set up properly, but the binary conversion is easily handled even by our plugin, whether it is encoding or decoding.
Let me provide an example.
First, you need to create an object in your database which contains a text field to store your binary data:
Then you can use our demo page to convert your text file into a binary, and save the resulted binary into created table:
And the next thing is setting up the API call itself:
Here we are using a JSON example of text just for testing purposes.
Then use the plugin with newly created API call to get results from:
And workflow action as well, on page load for example:
And if you want to preview the results back as decoded (your original JSON file), just use plugin’s state into a text element:
Hope it helps!
