Confirm the interface and its scope
An API is an interface with an expected contract. Before writing a request, confirm that the documentation describes an official interface available for your intended use. Identify the relevant version, environment, account conditions, and access requirements. A product may expose an internal request in its own application without offering that request as a supported public contract. Building on an undocumented observation can create a fragile connection whose behavior changes without the guarantees you expected.
Read the purpose of the operation before its example. Determine whether it retrieves information, creates a resource, updates state, or triggers a consequential action. The operation's meaning matters more than the convenience of a copied command. A request that appears similar to another request may have different side effects. Make sure the action corresponds to the workflow you intend and that the current task authorizes it.
Separate examples from configuration. A sample address, identifier, or credential may be illustrative. Look for the instructions that explain what must be replaced and where the real values come from. Do not invent an endpoint when documentation is absent, and do not assume that a product name implies a package name or SDK installation command. Confirming the interface is part of the integration work, not a preliminary detail that can be skipped.

Inspect inputs, outputs, and limits
For each request, identify required inputs, optional inputs, accepted types, valid ranges, and the meaning of omitted values. Pay attention to identifiers and time fields. A displayed name may not be a stable identifier, and a timestamp may require a specific time zone or format. Validate the shape of the request before sending it. Clear input handling makes failures easier to interpret and reduces the chance that an operation is applied to the wrong resource.
Read the response contract as carefully as the request. Identify where the result appears, whether the operation is complete or still pending, and which fields are optional. A successful transport status does not always mean that every intended action succeeded. Some interfaces report partial results or an asynchronous operation that must be checked later. The receiving code should follow the documented state rather than assume that the first response establishes the final outcome.
Look for pagination, rate limits, quotas, and ordering guarantees. A list response may contain only the first page. Records may change between requests. A limit may apply per account, token, operation, or time window. These details affect both correctness and efficiency. Avoid treating a small successful example as proof that the same approach will work for the full dataset. Test the behavior that the documentation describes and keep the assumptions visible in the integration design.
03 / DEVELOPMENT
Understand errors and repetition
Error information should help distinguish invalid input, missing access, an unavailable dependency, and a resource that does not exist. Use that distinction to decide what happens next. Retrying an invalid request without changing it will not solve the problem. Requesting broader access may be inappropriate when the task itself does not require it. A useful error strategy addresses the reason for failure rather than treating every non-success response as a temporary interruption.
Understand the effect of repeating an operation. Some interfaces provide a mechanism that lets the client recognize a repeated request and avoid creating a duplicate result. Other operations need the client to track what has already been completed. Do not assume that a timed-out response means the action never happened. The server may have completed the work before the connection was interrupted. Recovery needs a way to inspect or reconcile the actual state.
Use a controlled environment or a low-impact representative case where available. Verify both the response and the destination state. Remove secrets from shared examples and avoid logging complete authorization headers. Record the documented version and any assumptions the implementation relies on. When the interface changes, those notes make it easier to identify which behavior needs retesting instead of treating the whole integration as an unexplained failure.
A reference reading order
Read availability and authorization first, then the operation's purpose, request schema, response states, limits, errors, and repetition behavior. Finally inspect the example. This order makes the example easier to interpret and prevents it from becoming a substitute for the contract. If a necessary part is missing, keep the integration question open until reliable information is supplied.
