Postman pre-Script

Open up Postman and go to the Pre-request Script tab.  

 

Below is the skeleton that needs to be pasted into it if you don’t want to use the attached file:

 

const crypto = require('crypto-js');

const secret = ‘my-secret';

 

const body = {

    "event": "envelope-completed",   

    "data": {       

        "envelopeId": "2b6a9e15-b8ca-43f3-9e7b-e505504560ed",

        "envelopeSummary": {         

            "envelopeDocuments": [

                {

                    "documentIdGuid": "cbf2d203-12fd-4f93-9eb9-1e7e738e8206",

                    "PDFBytes": "",

                    "documentFields": [

                        {

                            "name": "DocumentRequestId",

                            "value": "1"

                        }

                    ]

                },

                {

                    "documentIdGuid": "090fe7f3-33ab-4ad9-b98a-d9d554616a1a",

                    "PDFBytes": ""

                }

            ]

        }

    }

};

 

const jsonString = JSON.stringify(body);

const hmac = crypto.HmacSHA256(jsonString, secret);

const signature = crypto.enc.Base64.stringify(hmac);

 

// Set environment variables

pm.environment.set("calculated_signature", signature);

pm.environment.set("request_body", jsonString);
