Hello @gearymarks,

No, you cannot automatically sign an agreement in DocuSign. Not in any traditional sense. I don’t know the implications of any legality around automatic signing of a document. Some questions to ask yourself would be, does automating a signature process by code impact: the “signers” intent to sign, implied or express consent of electronically signing, still represent an accurate signature attribution, allow for deliberate application of the signature by a person, etc. and ultimately, do those factors impact the legality of the signed document? 

On the technical side, you could utilize a browser automation tool to replicate human clicks on the DocuSign signing page to accomplish this as a task but I’d not recommend that route to anyone because of the unknowns around enforceability in such a scenario. E-signature does tend to be held to a higher standard to be considered enforceable in comparison to traditional ‘wet’ signatures.
