# Connect Todocolección to RUIT

Connect Todocolección to RUIT: ask Todocolección for the API key and your user ID through its contact form and paste them into RUIT when they arrive.

_Updated: 2026-09-28 · Source: https://ruit.es/en/docs/connect-todocoleccion/_

In this tutorial you connect your Todocolección account to RUIT. Todocolección connects with two
pieces of information, an **API Key** and your **User ID**, and it has a quirk that no other
marketplace shares: **you do not generate them yourself**. You ask Todocolección for them through
its contact form, they reach you by email and you paste them into RUIT. Your part takes **five
minutes**; the wait depends on Todocolección.

**You need** a seller account on Todocolección and a [verified phone](https://ruit.es/en/docs/verify-your-phone/),
because without it the connection wizard does not open.

> **Warning:** It is worth saying plainly, because it is the most common mix-up: **they are not your usual
> username and password**. Those cannot be used to connect, however well they work for signing in to
> the website.

## 1. Ask Todocolección for the API key and user ID

Sign in to your [Todocolección](https://www.todocoleccion.net) account and open its
[business information form](https://www.todocoleccion.net/contactar/informacion-comercial). The
website only exists in Spanish, so its labels are given here as they appear, with their meaning.
Fill in your name and email, choose `Otros motivos` (other reasons) under `Asunto` (subject) and,
in `Motivo de la consulta` (reason for your query), ask for your account's API key and user ID. For
example: "Good morning, I would like to request the API key and the user ID of my account so that I
can connect it to external management tools. Thank you." Press `Enviar consulta` (send query) and
**note down the query number** they give you.

The form, already filled in. What matters are the two marked fields: the subject and the message.

## 2. Wait for Todocolección's reply

Todocolección replies **by email**, and the two pieces of information come in that reply. In the
meantime you can see how your query is going on its
[contact page](https://www.todocoleccion.net/ayuda/contactar): type the number under
`Consulta frecuente (acceso directo)` (frequent query, direct access) and press `Continuar`
(continue).

The shortcut for following up a query you have already sent.

## 3. Paste the two details into RUIT

Go to **Settings → Accounts**, press **Connect Account** and pick **Todocolección**. Paste the key
into **API Key** and your identifier into **User ID**, and press **Connect**. There is no address
to type: the store is not yours, it is a marketplace.

The Todocolección dialog. The numbers mark **API Key** and **User ID**. The eye icon shows the key
while you check it.

RUIT tests the credentials by asking Todocolección for a product from your account. If they are
rejected, it tells you right there instead of leaving the account half set up.

## What you have achieved

Your account appears under **Connected Accounts** with its Todocolección card, which carries your
user ID. The credentials do not expire, so the card does not have the **Reconnect** button that
Wallapop and Vinted do: the connection lasts as long as Todocolección keeps the key valid.

**Next step:** importing from a marketplace to bring in the lots you already have on Todocolección,
or [publishing your first listing](https://ruit.es/en/docs/your-first-listing/).

## If something is off

- **"Failed to verify credentials. Please check your API keys and store URL."** Todocolección has
  rejected the details. The message mentions a store URL that does not exist here; what you need
  to check is the key, copied in full and with no spaces, and the ID.
- **You cannot find your user ID in the email.** It is the same one that appears in the address of
  your public profile, `todocoleccion.net/usuario/<your-id>`.
- **Later on, RUIT says "We need to validate your session again. Please link the account
  again."** Todocolección has stopped accepting the key. Ask it for a new one and repeat step 3.
