🔐Authentication

Authorization is an important step to using Open API. To be able to authenticate the store, you must generate a X-PGPrints-Hmac-Sha256. first of all you must have Secret Key.

Generator Secret Key:

Back in the Key Management section in the app, click the Generate Key button to get the secret key and copy the key

Generate Key

Generator X-PGPrints-Hmac-Sha256:

Make X-PGPrints-Hmac-Sha256 very simple by following steps:

1. Converts body value to a JSON string

2. Use the newly obtained secret key to make the key code

3. Use Json String body to the plain text

4. Use Sha256 to algorithm

5. Generator X-PGPrints-Hmac-Sha256

This is my code in some language:

Javascript

const crypto = require('crypto');
const generatePGPrintHmac = (content) => {
    const { body, secretKey } = content;
    // your body and your secrect key
    const sign = crypto
        .createHmac("sha256", secretKey )
        .update(JSON.stringify(body))
        .digest("base64");
    return sign;
}
