# API integration.

API integration is connecting systems through their programmatic interfaces: authentication, pagination, rate limits, error handling, retries and keeping up with changes on the other side.

## Where API integration fits on a long engagement.

The happy path is a small fraction of the work. What determines whether an integration is reliable is the handling of rate limits, partial failures, timeouts, inconsistent error formats and the provider's occasional undocumented behaviour change.

Rate limiting is the most commonly mishandled. An integration hitting a limit and retrying immediately makes the problem worse, and the correct behaviour — respecting the retry-after header, backing off exponentially, queueing rather than dropping — has to be built rather than assumed.

## What an assigned team does with API integration.

Third-party APIs change without notice. A field deprecated, an error format altered, a rate limit tightened — none of which arrive as a notification to whoever built the integration.

Monitoring for behavioural change rather than only for outright failure is what catches those early, and it is part of what assigned capacity is responsible for under [software development outsourcing](https://azendo.co/services/software-development/).

## What we use API integration for.

* Rate limits respected properly Backoff and queueing rather than retrying into a limit.
* Partial failure handled Batch operations where some items succeed, reconciled rather than retried wholesale.
* Provider changes detected Monitoring for altered behaviour, not only for outright errors.

## How API integration capacity is assigned.

Integration capacity is assigned inside the discipline that owns the consuming service, with provider change monitoring treated as part of the work.

## Roles we assign API integration for

* [AI Automation Engineer AI automation engineering](https://azendo.co/services/ai-automation-engineering/ai-automation-engineer/)

## Service lines it sits in

* [AI automation engineering](https://azendo.co/services/ai-automation-engineering/)

Capacity is agreed as a committed monthly capacity across a discipline, not per skill.
