CircleCI

API

Automate CI/CD pipelines for software development workflows

Overview

The CircleCI API enables programmatic management of CI/CD pipelines with endpoints for triggering builds, retrieving job/workflow statuses, accessing artifacts, configuring project settings, and fetching test results. Responses are in JSON format. Use cases include integrating pipeline statuses into dashboards, automating build triggers from external tools, managing environment variables, and orchestrating complex deployment workflows alongside GitHub, GitLab, or Jira.
