# Payline setup procedure

### Introduction

The "Payline Setup Procedure" feature allows customers to integrate the Payline (Monext) payment system to manage online transactions securely and efficiently. Here are the detailed steps to set up Payline in your Yoplanning.pro application.

### Steps to set up Payline

#### **Request for VAD number**

1. Contact your bank.
2. Make a request using this exact phrase:

   ```
   "Je voudrais un numéro de VAD pour notre système de vente en ligne sur notre site internet [https://monssite.com] pour un PSP externe qui s'appelle Payline (Monext)"
   ```

#### **Completing the form**

1. Once the bank has established the contract and provided the VAD number, please inform us, we will provide you with a document to complete.
2. Fill out the form with the necessary information.
3. Return the signed form along with your bank details to our team. (<support@yoplanning.com>)

#### **Payline Back-office Access**

You will then receive an email directly from Payline to create your account on the back office which will allow you to track transactions and carry out certain operations.

### Usage tips and best practices

* **Clear Communication with the Bank**: Use the exact phrase provided to avoid confusion.
* **Verification of information**: Make sure that all information on the form and RIB is correct before submitting it.
* **Rigorous Testing**: Perform production testing to ensure transactions run smoothly.

### Common Problems and Solutions

* **Problem: Errors in the Payline back office** **Solution:** If you encounter any problems during setup, consult Payline's documentation or contact their technical support for assistance. <support@yoplanning.com>
* **Problem: Tests fail in production** **Solution:** If the tests fail, check that all information is entered correctly and that the VAD number is valid. [Contact Yoplanning support if necessary.](/en/general-principles/support-contactez-nous.md)

Timeframe: Setting up a Payline contract takes 48 to 72 hours once you have obtained the VAD number from your bank.

**If the bank asks you for technical clarifications on the workflow, send the following article.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yoplanning.support/en/yoplanning-academy/yoplanning-parametrage/vente-en-ligne/procedure-de-mise-en-place-de-payline.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
