Why Outbound Webhook Providers Need Self-Serve Portals
You've built the webhook delivery pipeline. Events fire, payloads go out, consumers receive data. That seems like it's the hard part, but then the support tickets start rolling in.
"My endpoint stopped receiving events two days ago. What happened?", "Can you resend the webhooks from last Thursday?", "I need to change my endpoint URL — can someone on your team update it?" Every one of these is a problem your consumers could solve themselves, if you gave them the tools to do it.
A user portal for webhook consumers isn't a nice-to-have bolted on after launch. It's the interface that determines whether your webhook system scales with your customer base or drowns your support team in operational tickets. This post walks through what consumers actually need from a self-service portal, why each capability matters, and how Outpost can provide one out of the box if you'd rather not build it yourself.
The support burden nobody budgets for
Most teams underestimate the operational overhead of running an outbound webhook system. The delivery infrastructure gets the engineering attention (retries, signing, payload formatting) but the day-to-day reality of supporting consumers is where time quietly disappears.
Consumers need to register endpoints, rotate secrets, debug failed deliveries, and understand what events are available to them. Without a portal, every one of those actions becomes a support ticket or, worse, a manual database change by someone on your team. Multiply that across hundreds or thousands of consumers and you've built yourself a full-time job that didn't exist in the original project plan.
The providers who get this right (Stripe's developer dashboard being the canonical example) treat the consumer-facing portal as a first-class product surface. The ones who get it wrong leave their consumers navigating blind, filing tickets for things they should be able to handle in thirty seconds.
Destination management: the baseline
The most fundamental thing a webhook consumer needs is the ability to manage their own endpoints. This sounds trivially obvious, but a surprising number of webhook providers still handle endpoint registration through API-only flows or, worse, through their support team.
A good portal lets consumers create, update, disable, and delete their webhook destinations without touching your team. When an endpoint URL changes (and it will — infrastructure rotates, staging environments shift, teams migrate providers), the consumer should be able to make that change immediately rather than waiting for someone to process a ticket.
Disabling a destination temporarily is just as important. During maintenance windows or debugging sessions, consumers need a kill switch that pauses delivery without losing their configuration. Forcing them to delete and recreate a destination just to pause traffic is the kind of friction that erodes trust over time.
If your system supports multiple destination types beyond plain HTTP (message queues like SQS or RabbitMQ, event buses like EventBridge, streaming platforms like Kafka) the portal needs to surface each option with its specific configuration fields. The setup flow for an SQS queue is fundamentally different from a webhook URL, and the portal should guide consumers through the right steps for each.
Event visibility: the feature consumers ask for most
When a webhook delivery fails, the first question is always "what happened?" If the answer requires the consumer to file a support ticket and wait for someone on your side to dig through logs, you've failed them.
An event log is arguably the most valuable feature a webhook portal can offer. Consumers need to see their historical events — what was sent, when it was sent, and whether it was received successfully. They need to filter by status (delivered, failed, retrying), by destination, and by event type. They need to inspect the actual payload and the response their endpoint returned.
This transparency does two things simultaneously. It gives consumers the information they need to debug their own integration issues (a 500 response from their endpoint is not your problem to solve, but they need to see it). And it dramatically reduces the volume of "did you send the webhook?" support tickets that plague every provider without decent visibility tooling.
The delivery attempt history for a given event matters too. When a delivery fails and triggers retries, consumers should see each attempt — the timestamp, the response code, and the response body. This turns a mysterious "events aren't coming through" complaint into a self-diagnosable "ah, my endpoint was returning 503s for two hours during our deployment."
Manual retries: giving consumers control over recovery
Automatic retries with exponential backoff handle the common cases of transient failures, brief outages, and network blips. But they don't cover every scenario. Sometimes a consumer's endpoint was misconfigured for a week. Sometimes a deployment went wrong and they need to reprocess a day's worth of events after fixing the issue.
Manual retry is the feature that keeps consumers from panicking. The ability to select a failed event and trigger a re-delivery, or to bulk-retry all failures within a time window, turns a potential data-loss incident into a routine recovery operation.
Without this your team then has to figure out which events got missed, replay them manually from your side, and hope nothing goes wrong. With a retry button in the portal, the consumer handles it in minutes and your team never hears about it.
Topic-based subscription controls
Not every consumer needs every event type. A consumer building a billing integration only cares about invoice.paid and payment.failed — they have no use for user.profile_updated or inventory.adjusted. Sending everything to everyone wastes bandwidth, creates noise, and widens the security surface by streaming data to endpoints that don't need it.
A portal that lets consumers choose which event types (or topics) they subscribe to solves this cleanly. They see what's available, opt into what they need, and ignore the rest. When you add new event types later, existing integrations aren't disrupted by unexpected traffic.
This also simplifies the consumer's webhook handler code. Instead of receiving every event and implementing a type-based routing layer to discard the irrelevant ones, they only receive what they asked for. Less code, fewer edge cases, lower compute costs on their side.
Secret management and rotation
Webhook signatures are the trust layer between your system and the consumer's endpoint. If a consumer can't verify that a delivery actually came from you, their integration is vulnerable to spoofing. Per-destination signing secrets are table stakes, but managing those secrets over time is where things get complicated.
Secrets leak. Employees with access leave the company. Compliance policies mandate periodic rotation. When the time comes to rotate a signing secret, the consumer needs to do it without downtime, and that means supporting a grace period where both the old and new secrets are valid simultaneously.
A portal that surfaces the current signing secret (or lets the consumer regenerate it), explains how verification works, and handles the rotation window gracefully removes an entire category of security-related support interactions.
Alerting and notifications
Consumers shouldn't have to poll your portal to find out their integrations are broken. When deliveries to an endpoint start failing, the consumer should know about it before the failures stack up.
Alerting is the proactive counterpart to the event log. A well-designed portal lets consumers configure how they want to be notified (email, Slack, webhook) and under what conditions. Consecutive failures, error rate thresholds, or a destination being automatically disabled after too many failed attempts are all reasonable triggers.
This is the difference between a consumer discovering on Monday morning that their endpoint has been down since Friday night, and getting a notification within minutes of the first failure. That difference can translate directly into lost revenue or data integrity issues for your consumer, which ultimately reflects on your platform.
What Outpost provides
Building all of the above from scratch is a significant investment. Endpoint management, event storage, retry logic, a query interface for historical events, JWT-based authentication for the portal itself, theming, and ongoing maintenance — it adds up fast, especially when the portal isn't your core product.
Outpost, Hookdeck's open-source webhook infrastructure, ships with a tenant user portal that covers these needs out of the box. The portal is a React single-page application distributed via the Outpost API, and it supports the core self-service workflows: creating and configuring destinations, updating or deleting them, enabling and disabling delivery, viewing historical events with their payloads and responses filtered by status and destination, and manually retrying failed events.
Access is handled through a JWT generated from the tenant-specific portal endpoint. When a consumer is redirected to the portal, the token persists in their session and serves as the credential for the duration of their visit. You configure a referrer URL for navigation back to your application, set your organization name, and the portal is ready to serve your consumers.
Theming keeps the portal consistent with your brand. Light and dark modes are supported (configurable via query parameter or forced through a server-side setting), and you can customize the accent color and logo. If you'd rather not show Outpost's branding, a configuration option disables it entirely.
If the prebuilt portal doesn't fit your product's look and feel, or you need tighter control over the experience, Outpost exposes the same API that the portal itself uses. The Building Your Own UI guide walks through the full set of endpoints — listing destinations, fetching destination type schemas (including their configuration fields and setup instructions), creating destinations with topic selection, and querying events with delivery attempts.
This means you can build a fully custom portal that matches your product's design system while still benefiting from Outpost's delivery infrastructure, retry logic, per-destination signing, and secret rotation under the hood.
The portal is the product surface
Webhook infrastructure teams tend to focus on the delivery pipeline — and that's understandable, because unreliable delivery undermines everything else. But from the consumer's perspective, the portal is where they spend their time. It's where they set up their integration, where they go when something breaks, and where they decide whether your webhook system is something they can rely on or something they need to work around.
The providers that treat the portal as an afterthought end up subsidizing that neglect with support headcount. The ones that invest in genuine self-service build the kind of developer trust that compounds over time. And if building that portal from scratch isn't where you want to spend your engineering cycles, Outpost gives you a working starting point that you can deploy as-is or extend through its API.
