Before you make a decision
An integration can be convenient for users while creating another route to important business data. An API gateway can help manage API traffic, but the useful starting point is an inventory of the interfaces you expose and the clients that rely on them.
Inventory your interfaces first
List public APIs, internal services and partner connections. Record an owner for each interface and identify the data or operations it exposes. Include older versions and endpoints used by scheduled jobs. An accurate inventory helps distinguish a missing control from a feature you do not need, and gives vendors a more realistic basis for a demonstration.
Understand the controls you need
Ask how authentication, authorisation, rate limiting and request logging work across your applications. A gateway can provide shared controls, while the application still needs to enforce its own business rules. Decide which responsibilities belong in each layer. Avoid treating successful authentication as permission to perform every operation available through the API.
Model traffic and cost together
Estimate normal requests, bursts and background jobs. Check how the service bills for requests, data transfer, logging and additional environments. Ask what happens when a limit is reached and how clients should handle temporary failures. Include the cost of supporting development and test environments so the production quote does not hide the implementation effort.
Plan for changes and outages
Discuss configuration testing, versioning, rollback and service availability with the team responsible for operations. Review what happens if the gateway is unavailable and how the team detects that condition. Make sure logs are useful without exposing credentials or unnecessary personal data. A central control point needs clear operational ownership because configuration mistakes can affect several applications at once.
Pilot with one realistic integration
Choose a low-risk interface with enough traffic and complexity to reveal practical issues. Test permitted and denied requests, limits, timeouts and useful diagnostics. Record how clients behave when a request fails. The pilot should show how the product fits the application and support team, rather than simply prove that a sample request can return a successful response.
Your comparison worksheet
Bring these questions to the conversation
| Compare | Ask |
|---|---|
| Controls | Which policies apply before traffic reaches our app? |
| Billing | What counts as a billable request? |
| Reliability | How do clients behave during an outage? |
| Operations | Who tests and approves configuration changes? |
Your quick checklist
- Inventory APIs, versions and owners.
- Separate authentication from application permissions.
- Model requests, logging and transfer costs.
- Test limits, failures and configuration rollback.
