DocuSign API: “Invalid Signature Credentials” error using Captive (Embedded) Recipients
问题 I am using SOAP based API call "CreateAndSendEnvelope" to create an envelope into desired DocuSign account. When I add recipients as Captive/Embedded recipient(s), I am able to create an envelope fine but while requesting tokens for the captive recipients, I am getting an error "Invalid Signature Credentials". Here is my request that I have made against my DocuSign demo account. POST https://demo.docusign.net/api/3.0/dsapi.asmx HTTP/1.1 Content-Type: text/xml; charset=utf-8 X-DocuSign
