Una clave de API es una cadena única utilizada para identificar una aplicación o proyecto cuando realiza una solicitud a una API, a menudo para control de acceso, monitoreo y gestión de uso.

Clave de API

<h2>What Is an API Key?</h2><p>API Key is a string that identifies an application or project when it makes a request to an <a target="_blank" rel="noopener noreferrer" href="https://watchers.io/glossary/api">API</a>. The key is usually sent along with the request so the API can recognise the caller and associate the request with the right project. In many systems, API keys are also used for quota, billing, and monitoring.</p><p>Importantly, an API key is not usually about identifying an end user. It is mainly used to identify the calling app, service, or project. That is why API keys are common in server-to-server integrations, internal tools, and API-based products where the platform needs to recognise the client making the request.</p><h2>API Key vs. Access Token</h2><p>API keys and access tokens are related, but they are not the same.</p><p>Generally, an API key identifies the application or project making the request. An access token, meanwhile, is typically used to authorise access on behalf of a user, service, or application identity. Put more simply, an API key tells the API which app is calling, while an access token is more often used to prove that the caller has permission to access a protected resource or perform a specific action.</p><p>The difference matters because API keys are sometimes treated like a complete authentication system, although they are not really built for that. In many APIs, keys are used for identification, billing, quota management, and traffic control. Stronger authorisation is usually handled through access tokens, user credentials, service accounts, permissions, or other access controls.</p><h2>Using API Keys In Digital Products</h2><p>Product and engineering teams use API keys to connect apps, services, and integrations to APIs in a controlled way. They are often used for:&nbsp;</p><ul><li>identifying the calling app or project;</li><li>managing quotas and rate limits;</li><li>tracking usage for billing or monitoring;</li><li>restricting which services, referrers, IPs, or apps can use the key.&nbsp;</li></ul><p>API keys are sensitive credentials, so they need careful handling. Keeping them out of public code where possible, avoiding unnecessary exposure in URLs, applying restrictions to limit how each key can be used, deleting unused keys, and rotating keys when needed.&nbsp;</p><h2>How do Watchers use API Keys</h2><p>We have an API catalogue to connect your services with the Watchers platform to ensure a seamless experience for additional integrations. For example, you can start and finish in-chat live streaming automatically, send in-chat marketing offers with the linkage to your CRM system, synchronise badges with your main platform to ensure the end-to-end experience when users have the same achievements in their main profiles and in chat, and many more.</p><p><a target="_blank" rel="noopener noreferrer" href="https://watchers.io/catalogue-api"><strong>Read more about the various APIs we use to provide you with a seamless connection between chats and the host platform.</strong></a><br>&nbsp;</p>

Las métricas representan el conteo de usuarios únicos que interactúan con un producto o servicio digital dentro de un marco de tiempo específico. Estas métricas son la forma principal de cuantificar el alcance, la participación y el uso recurrente de una aplicación.

Métricas de Usuarios Activos (HAU, DAU, WAU, MAU)

<p>Metrics represent the count of unique users who engage with a digital product or service within a specific timeframe. These metrics are the primary way to quantify the reach, engagement, and recurring usage of an application.</p><h2>The Temporal Hierarchy</h2><p>The power of these metrics lies in their ability to capture usage behaviour across different periods. Every metric is calculated as the count of distinct user IDs that have triggered a predefined event within the following time frames:</p><figure class="table" style="width:100%;"><table class="ck-table-resized"><colgroup><col style="width:15.01%;"><col style="width:24.23%;"><col style="width:60.76%;"></colgroup><tbody><tr><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Metric</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Time Window</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Typical Use Case</span></div></td></tr><tr><td><strong>HAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>1 Hour</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>High-frequency apps (e.g., messaging, trading, live gaming).</span></div></td></tr><tr><td><strong>DAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>24 Hours</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Standard consumer apps, social media, productivity tools.</span></div></td></tr><tr><td><strong>WAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>7 Days</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>Professional software, weekly utility apps.</span></div></td></tr><tr><td><strong>MAU</strong></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>30 Days</span></div></td><td><div style="margin-bottom:0.5em;margin-top:0.5em;text-align:left;"><span>E-commerce, subscription services, low-frequency tools.</span></div></td></tr></tbody></table></figure><h2>Critical Technical Considerations</h2><p><strong>1. Defining the event to count</strong></p><p>A common pitfall in interpreting these metrics is uncertainty. Activeness is not a universal constant. Organisations define an active user based on their specific goals:</p><ul><li>Minimalist definition: A user who simply opens the application or faces a landing page.</li><li>Substantive definition: A user who performs a valuable action, like creating a post, completing a transaction, or watching a video.</li><li>Result: Comparing the active users of two different platforms is only valid if both entities define active users in the same way.</li></ul><p><strong>2. Unique user duplicates clean up</strong></p><p>The unique aspect is a critical technical constraint. These metrics must be cleaned up of duplicates. If a user logs in five times a day, they still have to be counted as one DAU. Systems typically handle this by tracking unique identifiers, like UserID, device ID, or hashed email, within the database logs for the specified query range.</p><p><strong>3. Meaningful Insights: The Ratio Analysis</strong></p><p>Analysts use these metrics to derive behavioural trends:</p><ul><li><strong>Stickiness</strong> (also known as<a target="_blank" rel="noopener noreferrer" href="https://watchers.io/growth"> engagement rate)</a>: It is calculated as MAUDAU​. This represents the percentage of monthly users who return to the product on any given day. A higher ratio indicates that the product has successfully woven itself into the user's daily habits.</li><li><strong>Retention</strong> velocity: By comparing WAU to MAU, it is possible to estimate how frequently users fall out of the active user base, helping to identify potential churn issues.</li></ul><p><strong>Why Context Matters</strong></p><p>These metrics are &nbsp;dependent on the natural frequency of the product. An application designed for filing taxes has a high MAU but a naturally low DAU. Conversely, a news aggregator would be considered failing if its DAU was not significantly higher than its MAU.</p>

Community chat is a real-time in-app conversation channel where many users discuss shared content or topics, distinct from private group chats and support chat1s.
