Why Bad Webhooks Make It Hard for Your API Partners to Build Automations and Integrations Around Your Platform

Webhooks are an essential tool for enabling third-party integrations and empowering customers and partners to build automations around your platform. However, many webhook systems fall short in certain areas, making it difficult for developers to work with them effectively.

Understanding these common shortcomings is crucial for improving webhook infrastructure and delivering a better experience to those trying to integrate with your platform. Here are 10 key issues to keep in mind.

1. Lack of Reliable Delivery​

One of the most common issues with webhooks is unreliable delivery. Webhooks are often sent over HTTP, and like any network communication, they are susceptible to failures such as timeouts or dropped connections. If your webhook system doesn't have proper retry mechanisms or error handling in place, it can leave customers guessing whether the data was successfully transmitted.

  • Impact: Imagine a developer trying to automate a critical process, such as payment processing or inventory updates, based on webhook notifications. If the webhook doesn’t consistently deliver the data or fails without retries, their automation breaks down. This creates additional work for developers to build custom retry logic, introducing friction and frustration.
  • Solution: Implement automatic retries with exponential backoff when a webhook delivery fails, and make sure to log and provide visibility into these failures so customers can investigate if something goes wrong.

2. Lack of Proper Authentication and Security​

Security is another area where webhook systems often fall short. Many platforms still use basic authentication methods like shared secrets, or worse, no authentication at all. This leaves webhooks vulnerable to spoofing or unauthorized access, especially when sent over unencrypted connections.

  • Impact: A poorly secured webhook can expose sensitive data, which is a major concern for developers dealing with personal information, payment data, or other critical business processes. For developers, integrating with a webhook system that lacks robust security features adds significant risk and requires them to build their own layers of security to protect the data.
  • Solution: Adopt strong authentication methods such as signed requests (e.g., HMAC with SHA256) and always transmit data over HTTPS. This gives developers confidence that the webhook payloads are legitimate and secure.

3. Poor or Inconsistent Documentation​

No matter how well-designed your webhook system is, without clear and detailed documentation, it’s nearly impossible for developers to use effectively. Common documentation issues include incomplete examples, lack of error codes, and not explaining how payloads are structured.

  • Impact: Poor documentation forces developers to spend extra time reverse-engineering your webhook system or rely on trial and error to figure things out. This creates a frustrating experience and can deter users from fully integrating with your platform.
  • Solution: Invest in comprehensive, developer-friendly documentation that covers everything from setting up webhooks to handling errors and retries. Include clear examples of typical payloads and responses, as well as how to verify and authenticate incoming requests.

4. Limited or Non-Customizable Payloads​

Another common shortcoming is the lack of flexibility in webhook payloads. Some platforms send every possible data field in a webhook, while others limit the payload to a minimal set of information. Both extremes can cause problems for developers.

  • Impact: A bloated payload that includes unnecessary data makes it harder for developers to parse and use the information they need. On the other hand, a sparse payload forces developers to make additional API calls to retrieve the missing data. In either case, it adds complexity to the integration process.
  • Solution: Offer customizable webhook payloads where users can select the specific data they want to receive. This allows developers to tailor the webhook to their needs and avoid unnecessary bloat or incomplete information.

5. Lack of Idempotency and Duplication Handling​

When webhook systems don’t handle idempotency—the guarantee that a webhook won’t cause multiple identical actions if sent multiple times—developers are forced to deal with duplicate webhook events.

  • Impact: If the same webhook is received twice, it can cause unintended side effects, such as double processing a payment or creating duplicate records in a database. Developers then have to build their own deduplication logic, adding to their workload and increasing the chances of bugs.
  • Solution: Implement idempotency keys or unique event identifiers that ensure each webhook event is processed only once, even if sent multiple times. This makes it easier for developers to handle retries and ensure consistent outcomes.

6. No Event Filtering or Subscription Management​

Many webhook systems don’t offer granular control over which events get sent to the customer. As a result, developers may receive a flood of webhook events they don’t care about, making it difficult to filter out the noise and focus on relevant data.

  • Impact: Receiving unnecessary webhook events can overwhelm a system, increase processing costs, and lead to poor performance. It forces developers to write additional code to filter out unwanted events, complicating their integration process.
  • Solution: Provide robust event filtering options that allow users to subscribe only to the events they care about. This not only reduces the load on developers but also ensures that webhook consumers receive only the most relevant data.

7. Inconsistent or Unclear Error Handling​

Developers need to know how to respond when something goes wrong during webhook processing. Inconsistent error codes or unclear error messages make it difficult for developers to diagnose problems.

  • Impact: If error handling is vague or inconsistent, developers may struggle to understand the root cause of a failure, leading to time-consuming debugging and a poor user experience.
  • Solution: Provide consistent error codes with detailed error messages and documentation. Ensure the webhook system has clear guidelines on how to handle different types of errors, including response codes and error-specific retry logic.

8. Lack of Scalability for High-Volume Events​

Webhook systems can become overwhelmed when dealing with a high volume of events, especially if they're not designed for scalability. This can lead to missed or delayed webhook deliveries.

  • Impact: For businesses with large-scale automation, an inability to scale can result in system failures, loss of real-time updates, and broken workflows. This forces developers to build extra logic to handle rate limits or missed deliveries.
  • Solution: Ensure the webhook system can handle high-volume events and implement rate-limiting strategies or batching capabilities. This allows developers to maintain performance and manage load spikes without custom workaround solutions.

9. Inflexible Retry Strategies​

Many webhook systems employ a rigid retry strategy that doesn't adapt to the nature of the error or the partner's system requirements. Some errors might require immediate retries, while others could benefit from delayed retries, but a one-size-fits-all approach can create inefficiencies.

  • Impact: If the retry strategy is too aggressive, it can overwhelm the receiving system during a downtime or temporary issue. Conversely, if retries are too slow, it can cause delays in processing critical events like transaction confirmations, leading to poor user experiences.
  • Solution: Offer customizable retry strategies, allowing developers to define how and when retries should happen based on the error type or their system's needs. This flexibility ensures more efficient error handling and reduces unnecessary strain on both systems.

10. Lack of Visibility and Debugging Tools​

Many webhook systems provide little to no tooling for monitoring, debugging, and managing webhook events in real time. Developers are left in the dark when issues arise, with minimal insight into failures or delays.

  • Impact: Without visibility into webhook activity, developers struggle to identify problems quickly and efficiently, leading to slower resolution times and more manual work.
  • Solution: Offer comprehensive monitoring and debugging tools, such as logs, dashboards, or real-time event tracing. This allows developers to troubleshoot issues and monitor webhook performance directly through the platform.

Final Thoughts​

A reliable webhook system can significantly enhance the developer experience and improve integration success rates. However, when webhook systems suffer from common issues such as unreliable delivery, poor documentation, or lack of security, they make it harder for customers and partners to integrate effectively. By addressing these shortcomings—through better documentation, robust security practices, customizable payloads, and more—your webhook system can become a powerful tool that empowers developers and drives growth for your platform.
