How to place a signature field on dynamically generated pdf from a 3rd party .

Hey Gotcha, From the sounds of it, your best option is probably to use our Text Anchors feature. This allows you to use text from the document to specify the location of the signature block by the occurrence of that text. So, you can use the text that would be next to the signature. For example, if your signature area on the document looks like this: "Signature: ________________________-", you could anchor the signature based on the text "Signature". The only other thing you'd need to know is what occurrence of that word it is in the document. If there is only once occurrence, that's easy. If there are multiple signature blocks, you'd need to know how many. If there are multiple signers and multiple signatures, you'd need to be able to distinguish between them based on other text around, like "Employee Signature: _________________" and "Manager Signature: ________________" or something like that. Hopefully this explanation makes sense. You can find the guide for this feature, here: Text Anchors Guide
