We welcome your thoughts on how we could best provide you with SDKs that would simplify how you consume our services in your application. You can fork and create pull requests for any features you would like to see or raise an issue
To be able to use this SDK, you will need a public key provided by MessageMedia. You can find out how to do this by going through the Signature Key Management documentation. You can then make use of the Signature Key Management NodeJS SDK to create and manage your keys.
To keep this guide simple and easy to understand, we've used Express to set up a server which will monitor for incoming webhooks. You can setup your own production server and use it instead of the Express one if needed.
Create an empty directory for your project, let’s name it “testApp”. Now, open up your command prompt and clone this repository into the directory created.
Run npm install to install the necessary packages.
Open up the index.js file and replace the placeholder that says PUBLIC_KEY_HERE with your public key. The result should look like this:
var publicKey = '-----BEGIN PUBLIC KEY-----\n'+
'MIIabcdNBgkqhkiG9w0BAQ4AAOCA338AMIIBCgKCAQEAwISbN8vv0HeUCPN9o29xCUzCsh0ZUM+wdc3Gi3+DfyO4rPec1f/uxFbw0Dscw1iEA1dUfQ5eKhhsOIPdjk//gOGQbBVmQ8DhDcGVGWrHrE/n/K/x0ZkIae4n4eNobK96Ic/C4YmXf5LBUmgkOwUM+5VDPxe3rMnm/3TQdJzAcBMIzqNixzseCh4ICYMSahKnkNY5bJGf+8WbT0i+3mHQwvLacAub+wFH6hyT4I7FXOcXmR+HIyD8xwwYLmB4Yy+cMmiDcc1J9KX34C5apXM2A3f2mOtgfM0WSH2NpXmZmpXmzbkbIxEw90N3zERrDb2myJAHAD0MKQ7abcdxPen96dIDAQAB\n'+
'-----END PUBLIC KEY-----';The request line will need to be changed according to your callback url and request type. For instance, if your callback url is /captureData and the method type was PATCH then the resulting request line would look like this:
verifier.update("PATCH /captureData HTTP/1.1" + date + body);You are now ready to test the application. From the root directory of your application (where your index.js file is), run node index
If all goes well, you should receive a true response which indicates the verification was a success.
