how to create an hmac signature that combines a secret key and a json payload in suitescript 2.0

AI generated answer (using internal Slack threads):

To create an HMAC signature that combines a secret key and a JSON payload in SuiteScript 2.0, you can use the

N/crypto

module. Here is a step-by-step guide on how to do it: 1. First, you need to create a secret key. You can do this using the

crypto.createSecretKey

method. The secret key is usually provided by the service you are trying to connect to. In NetSuite, you can store this secret key using Secrets Management.

javascript
var secretKey = crypto.createSecretKey({
    encoding: encode.Encoding.HEX,
    secret: 'mysecret'
});

2. Next, you need to create an HMAC object. You can do this using the

crypto.createHmac

method. The algorithm you use depends on the requirements of the service you are connecting to. In this case, we are using SHA256.

javascript
var hmacSHA256 = crypto.createHmac({
    algorithm: crypto.HashAlg.SHA256,
    key: secretKey
});

3. Now, you can update the HMAC object with your JSON payload. You can do this using the

hmacSHA256.update

method.

javascript
hmacSHA256.update({
    input: inputString
});

4. Finally, you can generate the HMAC signature. You can do this using the

hmacSHA256.digest

method. The output encoding you use depends on the requirements of the service you are connecting to. In this case, we are using HEX.

javascript
var digestSHA256 = hmacSHA256.digest({
    outputEncoding: encode.Encoding.HEX
});

Please note that the

inputString

in the

hmacSHA256.update

method is the JSON payload you want to sign. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
