README

DocuSign eSignature RestApi v2 and v2.1(Beta) for Go

GoDoc

esign provides Go packages for interacting with DocuSign's eSignature RestApi and has been created using the lastest published swagger definition. Definitions for call payloads and return values are found in {VERSIONID}/model/model.go file.
Docusign has split the API into major categories, and each category has a corresponding package in the v2 and v2.1 directory.

The package requires Go 1.7 or above and has been tested with Go 1.9-1.12.

The previous package github.com/ICGGroup/docusign is now deprecated.

Announcements

eSignature v2.1 and click api are now available.

Resources

Official documentation: https://developers.docusign.com/

Package Updates

All packages, excepte for gen-esign and legacy, are generated from DocuSign's OpenAPI(swagger) specification using the gen-esign package.

Corrections to field names and definitions are documented in gen-esign/overrides/overrides.go.

The package names correspond to the API categories listed on the DocuSign REST API Reference page. Each operation contains an SDK Method which corresponds to the package operation which you will find in operation definition.

Authentication

Authentication is handled by the esign.Credential interface. OAuth2Credentials may be created via the OAuth2Config struct for 3-legged oauth and the JWTConfig struct for 2-legged oauth. Examples are shown for each in the esign examples.

UserID/Password login is available via the legacy.Config which may also be used to create non-expiring oauth tokens (legacy.OauthCredential). Examples are shown in the legacy package.

Models

The model package describes the structure of all data passed to and received from API calls.

Operations

Each package has a service object which is initialized via the .New() call. The service methods define all operations for the package with corresponding options. An operation is executed via a Do(context.Context) function. A context must be passwed for all operation

Example

Create envelope

	}
}

Output:

func (*JWTConfig) Credential 

func (c *JWTConfig) Credential(apiUserName string, token *oauth2.Token, u *UserInfo, scopes ...string) (*OAuth2Credential, error)

Credential returns an *OAuth2Credential. The passed token will be refreshed as needed. If no scopes listed, signature is assumed.

func (*JWTConfig) ExternalAdminConsentURL 

func (c *JWTConfig) ExternalAdminConsentURL(redirectURL, authType, state string, prompt bool, scopes ...string) (string, error)

ExternalAdminConsentURL creates a url for beginning external admin consent workflow. See https://developers.docusign.com/esign-rest-api/guides/authentication/obtaining-consent#admin-consent-for-external-applications for details.

redirectURL is the URI to which DocuSign will redirect the browser after authorization has been granted by the extneral organization's admin. The redirect URI must exactly match one of those pre-registered for the Integrator Key in your DocuSign account.

authType may be either code (Authorization Code grant) or token (implicit grant).

state holds an optional value that is returned with the authorization code.

prompt determines whether the user is prompted for re-authentication, even with an active login session.

scopes permissions being requested for the application from each user in the organization. Valid values are 

signature — allows your application to create and send envelopes, and obtain links for starting signing sessions.
extended — issues your application a refresh token that can be used any number of times (Authorization Code flow only).
impersonation — allows your application to access a user’s account and act on their behalf via JWT authentication.

func (*JWTConfig) UserConsentURL 

func (c *JWTConfig) UserConsentURL(redirectURL string, scopes ...string) string

UserConsentURL creates a url allowing a user to consent to impersonation https://developers.docusign.com/esign-rest-api/guides/authentication/obtaining-consent#individual-consent

Example 
package main

import (
	"context"
	"log"

	"github.com/ICGGroup/esign"
)

func main() {
	// Prior to allowing jwt impersonation, each user must
	// provide consent.  Use the JWTConfig.UserConsentURL
	// to provide a url for individual to provide their
	// consent to DocuSign.
	apiUserID := "78e5a047-f767-41f8-8dbd-10e3eed65c55"

	cfg := &esign.JWTConfig{
		IntegratorKey: "51d1a791-489c-4622-b743-19e0bd6f359e",

		AccountID: "c23357a7-4f00-47f5-8802-94d2b1fb9a29",
		IsDemo:    true,
	}

	// the redirURL must match one entered in DocuSign's Edit API
	// Integrator Key screen.
	consentURL := cfg.UserConsentURL("https://yourdomain.com/auth")
	_ = consentURL
	// redirect user to consentURL.  Once users given consent, a JWT
	// credential may be used to impersonate the user.  This only has
	// to be done once.
	ctx := context.TODO()
	cred, err := cfg.Credential(apiUserID, nil, nil)
	if err != nil {

	}
	u, err := cred.UserInfo(ctx)
	if err != nil {
		log.Fatalf("%v", err)
	}
	log.Printf("%s", u.Name)

}

	}

}

Output:

func (*OAuth2Config) AuthURL 

func (c *OAuth2Config) AuthURL(state string, scopes ...string) string

AuthURL returns a URL to DocuSign's OAuth 2.0 consent page with all appropriate query parmeters for starting 3-legged OAuth2Flow.

If scopes are empty, {"signature"} is assumed.

State is a token to protect the user from CSRF attacks. You must always provide a non-zero string and validate that it matches the the state query parameter on your redirect callback.

func (c *OAuth2Config) Exchange(ctx context.Context, code string) (*OAuth2Credential, error)

Exchange converts an authorization code into a token.

It is used after a resource provider redirects the user back to the Redirect URI (the URL obtained from AuthCodeURL).

The code will be in the *http.Request.FormValue("code"). Before calling Exchange, be sure to validate FormValue("state").

	"fmt"
	"log"

	"github.com/ICGGroup/esign"
	"github.com/ICGGroup/esign/v2.1/folders"

	// retrieve token frm DocuSign OAuthGenerator
	// https://developers.docusign.com/oauth-token-generator
	// or generate or
	var accessToken = `eyJ0eXAiOiJNVCIsImF...`
	credential := esign.TokenCredential(accessToken, true)

SetClientFunc safely replaces the ctxclient.Func for the credential

func (*OAuth2Credential) Token 

func (cred *OAuth2Credential) Token(ctx context.Context) (*oauth2.Token, error)

Token checks where the cachedToken is valid. If not it attempts to obtain a new token via the refresher. Next accountID and baseURI are updated if blank, (see https://developers.docusign.com/esign-rest-api/guides/authentication/user-info-endpoints).

func (*OAuth2Credential) UserInfo 

func (cred *OAuth2Credential) UserInfo(ctx context.Context) (*UserInfo, error)
