If secondInstallmentPaymentDate is lower than payment created date we do not consider secondInstallmentPaymentDate value.

For regulation purpose, the funding duration cannot exceed 12 months. Thus, if secondInstallmentPaymentDate is too far from created date, we aggregate the exceeding installments into one (see example below).

Examples:

A 5 installments payment of 500€ created on 2020-01-01 with no secondInstallmentPaymentDate:
- 1st share: 100€, due the 2020-01-01
- 2nd share: 100€, due the 2020-02-01
- 3rd share: 100€, due the 2020-03-01
- 4th share: 100€, due the 2020-04-01
- 5th share: 100€, due the 2020-05-01
A 5 installments payment of 500€ created on 2020-01-01 with secondInstallmentPaymentDate = "2020-05-15":
- 1st share: 100€, due the 2020-01-01
- 2nd share: 100€, due the 2020-05-15
- 3rd share: 100€, due the 2020-06-15
- 4th share: 100€, due the 2020-07-15
- 5th share: 100€, due the 2020-08-15
A 5 installments payment of 500€ created on 2020-01-01 with secondInstallmentPaymentDate = "2020-11-15":
- 1st share: 100€, due the 2020-01-01

# Signature of the parameters

The settings can be signed through an additional setting called signature which contains a JSON Web Token (JWT).

This token is generated with a secret shared between Pledg and the merchant. The merchant uses this secret on its backend to generate the token, and Pledg uses the same secret to decode it.

The merchant can also specify a validity period when generating the token.

The payload of the token is a JSON containing all the settings normally passed to the solution, except:

The parameter signature itself
The callbacks (in integration by plugin)
The parameter containerElement (if any, in integration by plugin)

The code below illustrates how to generate the JWT on the backend of the merchant. More precisely, the JWT is based on the data sent by the frontend, computed on the backend and returned to the frontend.

app.post('/generate-signature', function (req, res) {
    data = req.body
    var jwt = require('jsonwebtoken');
    var signature = jwt.sign(
        {
            data:data,
        },
        process.env.SECRET,
        { expiresIn: '1d' }
    );
    res.send(JSON.stringify(signature))
});

In this particular example:

It is written in JavaScript, but it could be any other backend language (Python, PHP, Java, etc.)

The library jsonwebtoken used here to generate the signature must be installed on the backend. It can be found there (opens new window) with the instructions to install it.
req is the request sent by the frontend, which body contains the parameters of the purchase (amounCents, title, etc.)
res is the response sent back to the frontend, which body contains the JWT.
The frontend is then supposed to call the URL of the backend related to the code above, retrieve the JWT from the response and set it in the field signature..

Finally the response of this request is a JSON web token so when your frontend will call '/generate-signature' it will get as a response "signature" which has to be injected in the field "signature" of the plugin.

Many technical resources related to JWT (documentation, validation tools, etc.) are available on https://jwt.io.
