The problem

Modern microservices architectures heavily rely on third-party APIs for essential functions like sending emails (SendGrid), SMS (Twilio), payment processing (Stripe), or identity management (Auth0). When one of these external services goes down or experiences degraded performance, it can cause cascading failures across your microservices, leading to lost revenue, failed customer interactions, or a poor user experience. Developers often struggle to differentiate between internal service issues and external dependency outages, wasting valuable debugging time.

Without dedicated, proactive monitoring of these external APIs, issues often only become apparent when customers report problems, or when your internal dashboards show downstream errors. Many teams only have passive monitoring of their own services, overlooking the critical health of the services they integrate with. Reacting to external outages is far more costly than being instantly notified, allowing your team to quickly implement fallbacks, communicate proactively, or switch providers if necessary, minimizing user impact.

How Tickr solves it

Continuously probe critical third-party API endpoints, such as Twilio or SendGrid, to detect issues.

Validate expected HTTP status codes (e.g., 200 OK) to ensure external services are responsive.

Receive immediate email and Telegram alerts if an external dependency experiences an outage.

Concrete example


// Example: Monitoring a third-party API endpoint (Twilio)
// Tickr probes this to ensure your SMS/voice services are functional.

<div class="highlight"><pre><code>
<span class="c1"># Simple GET request to Twilio's API endpoint</span>
curl -X GET https://api.twilio.com/2010-04-01/Accounts.json \
  -u "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:your_auth_token"

<span class="c1"># Tickr expects a 200 OK response from Twilio</span>
</code></pre></div>

Frequently asked questions

Can Tickr monitor authenticated third-party APIs?

Yes, Tickr supports basic authentication and custom headers, allowing you to monitor most authenticated public API endpoints effectively.

How does Tickr help identify if the problem is internal or external?

By monitoring specific external endpoints, Tickr directly tells you if the third-party service is failing, helping you quickly rule out internal issues.

What if an external API is slow but not completely down?

Tickr focuses on uptime and HTTP status codes. While it won't provide detailed performance metrics, a slow response might eventually lead to a timeout if configured, triggering an alert.
