# a3factura

> How to connect your a3factura account: what you need, how to prepare it, and how to connect.

# 🚨 Prerequisites

Before you start, make sure you have:

* an active a3factura subscription (a3facturago or a3facturapro)
* the **Conectia** module on that subscription, Wolters Kluwer's API module: without it, the connection cannot work
  * It is not included by default in a3facturago or a3facturapro.
  * Its price is not published: ask Wolters Kluwer or your distributor.
* a Wolters Kluwer user (email and password) with access to the company you want to connect
* for the preparation, access to **Conectia** in My Wolters Kluwer, to copy the Conectia API key. Don't see Conectia in the menu? Ask your account administrator to give you access.

# 🛠 Preparation

**1. Open the Conectia module**

Sign in to [My Wolters Kluwer](https://miwolterskluwer.com). In the menu on the left, under **My solutions**, click **Conectia**.

**2. Copy your API key**

Next to **Apikey**, click **Copy**. Keep it somewhere safe: you will paste it into the connection form, where it is called **Subscription Key**.

No API key yet? Generate it first, as Wolters Kluwer explains in [Conectia: qué es y cómo funciona](https://a3responde.wolterskluwer.com/es/s/article/conectia-que-es-y-como-funciona).

# ⚡️ Connection

**1. Name your connection**

In **Name of connection**, choose a name you will recognize later.

**2. Fill in your subscription key**

| Field | What to enter |
| - | - |
| **Subscription Key** | The API key you copied from Conectia in the preparation |

**3. Click Connect**

You are redirected to Wolters Kluwer to sign in.

# ✅ Authentication

Sign in with your Wolters Kluwer account, the one you use for a3factura.

![The Wolters Kluwer Account sign-in page, asking for an email](https://mintcdn.com/chift/6dBoThaErJB9PM8-/images/help/a3factura/a3factura-5.png?fit=max\&auto=format\&n=6dBoThaErJB9PM8-\&q=85\&s=04f797cd00cc5c4bb8a6dd75d9608b99)

On **Selección de aplicación**, pick the company you want to connect. Each connection reads one company: to connect another one, create another connection.

![The Wolters Kluwer application selection screen, listing the companies you can connect](https://mintcdn.com/chift/6dBoThaErJB9PM8-/images/help/a3factura/a3factura-6.png?fit=max\&auto=format\&n=6dBoThaErJB9PM8-\&q=85\&s=4a3bf1f6583d4400640ba1bfaf6ce7e7)

Wolters Kluwer asks you to confirm with multi-factor authentication (MFA). The first time, it walks you through setting it up.

Once you pick the company and confirm, you return to the connection window and the connection is active.

# ❓ Troubleshooting

> [accordion] Authentication with a3factura failed. Please reconnect your a3factura account.
>
> a3factura no longer accepts the connection's access. Two common causes:
>
> * The **Subscription Key** is wrong, or it was regenerated in Conectia. Copy it again from Conectia in My Wolters Kluwer, then connect again.
> * Your password changed, or the authorization was revoked. Connect again and sign in with your Wolters Kluwer account to renew the access.

> [accordion] Impossible to retrieve data from a3factura due to a permission issue.
>
> The user you signed in with is not allowed to read this data in a3factura.
>
> Ask your a3factura administrator to check the user's access, then connect again.
