# Réactiver une alerte properties

> Réactiver une alerte properties précédemment désactivée.

`GET /v2/protected/properties/search/alerts/{alertId}/activate` rebascule à `true` le flag `activated` d'une alerte mise en pause via [`DELETE`](/api-v2-reference/properties-alerts/deactivate-a-property-search-alert).

<Note>
  Le verbe HTTP est `GET` pour des raisons historiques (legacy). Idempotent — réactiver une alerte déjà active n'a pas d'effet.
</Note>

**Comportement post-réactivation** : l'alerte reprend les nouveaux matches `ALERT_MATCH_CREATED` à partir de l'instant `t` de réactivation. Si `ALERT_MATCH_MERGED` est dans le tableau `match`, les fusions reprennent uniquement sur les **properties qui étaient déjà matchées avant la désactivation** — pas de rattrapage des fusions survenues pendant la pause.

## Cas d'usage

* **Pause saisonnière** — désactiver hors campagne, réactiver pour reprendre la collecte.
* **Bascule budgétaire** — couper les alertes les moins prioritaires en pic de volume.

  title: Real-estate data API - Fluximmo V2
  description: >+
    ## Fluximmo

    ##### Real-time real estate data: Power workflows, business applications and
    decision-making.


    Real estate expert since 2017, Fluximmo aggregates, exploits, enriches &
    analyzes the 


    real-estate market in real time to offer data flows, APIs and innovative
    services to real estate professionals.


    ## Authentification

    You'll need to be authenticated with an active subscription to access our
    REST endpoints.


    To get an API-KEY please contact us at contact@fluximmo.com or book a call
    with our team: https://calendly.com/fluximmo/meet-fluximmo

    ##### How to use your API KEY

    Simply add to your HTTP request your API KEY in the headers:
    `{'x_api_key':'randomApiKey'}`


    ## Properties and Adverts

    Real-estate market can be conceptualized in different ways. We offer two
    different conceptualization depending on your needs: Properties & Adverts.

    #### Properties (BAAS)

    A property is a real-estate habitation/land/commercial/building to which is
    attached adverts.


    We gather all the adverts offering (selling or renting) this real-estate
    asset and consolidate all the information into one Property.


    A Property is by definition `de-duplicated` and can gather 1 to x adverts:
    these adverts are either duplicates from different portals or with mandates
    from different agencies or republication of the same advertising with a
    price update or not.


    The concept of property is in constant mutation until the real-estate asset
    is sold: We'll keep merging new adverts within the Property concept and
    update the price if needed.


    By it's nature in constant mutation, we do not offer the possibility to
    receive these Properties on webhooks. You'll need to use our APIs as a
    Backend As A Service (BaaS).


    #### Adverts (BAAS and WEBHOOK)

    Adverts are advertising of a real-estate property. Adverts can come from
    many sources: Agencies websites, Aggregation real-estate portals,
    Social-Networks, NewsPaper etc...


    After gathering all these adverts our proprietary AI algorithms will
    de-duplicate these adverts and associate them to a Property


    An advert have a unique URL. Meaning that the same advertising re-published
    twice (with our without any change, on the same website or not, by the same
    agency or not) is considered as 2 ads.


    You can choose either to retrieve all the Adverts or only the non duplicated
    ones. Adverts can be retrieved either by API (Search or Alerts) or Webhook

    ## Webhooks

    We offer the possibility to receive our real-estate Adverts data in
    real-time using webhooks. As soon as we gather the data, you'll receive it
    few moments later.


    Using ALERTS, you can receive new adverts matching your criteria on a
    webhook.


    ##### Webhook differences between Adverts and Properties

    As Properties are by nature in perpetual evolutions (new duplicated ads will
    be merged, new data to be consolidated etc..), we do not offer the
    possibility to receive through Webhooks the full body of the properties.
    Properties webhook will only send you the list of the properties FlxIds
    matching your search.


    You'll find below the schema of the data you would receive on your webhook
    (`/v2/sample/webhook/properties`, `/v2/sample/webhook/adverts`)

    ##### What is a webhook

    A webhook can be thought of as a type of API that is driven by events rather
    than requests


    .Instead of one application making a request to another to receive a
    response, a webhook is a service that allows one program to send data to
    another as soon as a particular event takes place.


    Webhooks are sometimes referred to as “reverse APIs,” because communication
    is initiated by the application sending the data rather than the one
    receiving it.


    With web services becoming increasingly interconnected, webhooks are seeing
    more action as a lightweight solution for enabling real-time notifications
    and data updates without the need to develop a full-scale API.

    ##### When to use a webhook instead of the REST API

    You're supposed to receive a high volume of data (frequently or not), you're
    looking for real-time data, you just have to relax and wait (no cron, no
    call on our API etc..)

    ##### Webhook implementation examples

    A webhook is simply a POST endpoint we can request
