Sorry if it's someplace obvious, but I'm not currently finding it. I was hoping it'd be in the Guides or Recipes section, but perhaps I can add that after I figure it out. I'm simply trying to get started.
My question is: when I update a pre-written PDF, how do I specify which text is variable data? I'd think perhaps surrounding a keyword with square brackets or something like that. Then I'd presume I'd send a key-value pair json data packet that would map to that keyword in my PDF?
Am I anywhere near the mark on this? Is there a link to any docs that would show me how to quickly get started with uploading a PDF and then writing my API calls to send off my letter(s)?
Thank you. I'm excited about the potential.
