Populate signature from signature_image table onto the fillable PDF via the Employee Service Center

[ArpitaVK]

I have a requirement where the signature (stored in signatre_image table) should get populated onto the fillable PDF, when the E-signature task is assigned to the respective assignee. I referred to the below mentioned article. 
Fill fields AND adding an image (signature) in a PDF using Quebec API "PDFGenerationAPI" 

But this article is for UI action which populates the signature. I wonder if it will work for employee service center(esc). Please guide me if you have any other solution.

Hi there,

Yes the example is for a UI Action. Though I clearly mentioned in my article:

"Also, this example is code used in a UI Action. Though you could go crazy on this! Automating the generation of the PDF, or sending the created PDF by email to the user, uploading the PDF to a server, etcetera. You don't have to limit this to manually executing a UI Action which just attaches a PDF to the current record."

Kind regards,
Mark
