Define your parameters. Write your prompt in plain English. Get a fully functional REST endpoint that returns structured JSON - in under 60 seconds.
Building AI-powered features into your product usually means weeks of backend development, prompt engineering, infrastructure setup, and deployment headaches. What if you could skip all of that and go from an idea to a live REST API endpoint in under 60 seconds?
That is exactly what Custom Workflows delivers. A visual builder in the SharpAPI Dashboard lets you define typed input parameters, write your processing logic as a plain-English prompt, and generate a production-ready API endpoint on the spot. The result is a fully authenticated REST API that accepts your inputs, runs them through the AI model of your choice, and returns structured JSON matching the output schema you defined. No backend code. No deployment pipeline. No infrastructure to manage. Just your idea, instantly available as an endpoint.
Every development team has a backlog of AI features they want to build. Extract data from invoices. Classify support tickets. Generate product descriptions. Score leads. Moderate content.
Each of these features follows the same pattern: take some input, send it to an AI model, parse the response, and return structured data. And yet, building each one from scratch means writing boilerplate code, handling API communication with model providers, parsing unpredictable outputs into reliable schemas, setting up async processing for long-running tasks, and deploying the whole thing somewhere.
Custom Workflows eliminates every one of those steps.
The Custom Workflows builder lives right in the SharpAPI Dashboard. It walks you through five straightforward steps:
Step 1: Basic Info. Give your workflow a name and description, then choose your input mode (JSON for structured data or Form-Data for file uploads).
Step 2: Parameters. Define your input parameters with types, labels, default values, and required/optional flags. The system supports the full range of types you would expect: strings, numbers, booleans, arrays, and objects for JSON mode, plus text and file inputs for Form-Data mode.
Step 3: AI Prompt. Write what you want the AI to do, in plain English. No prompt engineering expertise needed. If you are not sure where to start, pick one of the pre-made templates (more on those below) and customize it.
Step 4: Output Schema. Define the JSON structure you want back. Or just click one button and let the AI analyze your workflow context to suggest an optimal schema automatically.
Step 5: Review & Save. Preview everything, activate, and grab your endpoint URL. You are live.
That is the whole process. Five steps, and you have a production API.
Every saved workflow immediately becomes a live REST endpoint:
POST /api/v1/custom/{your-workflow-slug}
It uses the same API key authentication (X-API-KEY header) as every other SharpAPI endpoint. No additional setup or configuration.
Processing follows the standard SharpAPI async pattern for reliability at scale. You send a POST request and get back a 202 Accepted with a status_url and job_id. Poll the status URL until the job completes, then retrieve your structured JSON result matching the exact output schema you defined.
Every workflow also exposes a self-describing GET endpoint that returns its complete specification: parameter definitions, types, labels, required flags, defaults, output schema, and endpoint URL. This is perfect for auto-generating client code or feeding into other AI systems that need to understand what your API does.
The parameter system is strict by design. Every input parameter is validated against its declared type before any processing begins. Required parameters must be present. Default values fill in for optional ones. And in JSON mode, unknown parameters are automatically rejected, preventing typos and unexpected inputs from sneaking through.
This gives you the kind of type safety you would normally need backend code to enforce, except you get it for free.
Here is where it gets practical. Custom Workflows can power a wide range of features across industries:
Document Processing. Upload invoices, contracts, receipts, or forms and extract structured data at scale. Pair Form-Data input mode with a file parameter and you have a document processing API in minutes. Think insurance claim forms, medical records intake, shipping manifests, purchase orders, or tax documents.
Content Analysis. Sentiment analysis, content moderation, tone detection, urgency classification. Feed text in, get structured scores and labels out. Great for analyzing customer reviews, social media mentions, support tickets, survey responses, app store feedback, and forum posts.
Content Generation. Automated email drafts, product descriptions, social media posts, marketing copy. Consistent, on-brand content delivered via API. Use it for personalized outreach emails, SEO meta descriptions, product listing copy for e-commerce catalogs, newsletter sections, ad variations, or localized marketing content.
Data Enrichment. Add AI-powered insights, classifications, and predictions to your existing data pipelines. Plug a Custom Workflow into your ETL process and enrich records as they flow through. Classify CRM leads by intent, tag support conversations by topic, extract skills from resumes, or categorize transactions by spend type.
Risk Assessment. Compliance checking, fraud detection signals, policy violation screening. Get structured risk scores through a simple API call. Screen user-generated content for policy violations, flag suspicious transaction patterns, evaluate vendor contracts for non-standard clauses, or check marketing copy against regulatory guidelines.
Customer Support Automation. Route incoming tickets to the right team, suggest reply templates, extract key details (order numbers, product names, issue categories) from customer messages, or generate first-draft responses for agents to review.
E-commerce & Product. Automate product categorization and tagging, generate comparison tables, extract specs from manufacturer datasheets, translate listings for international storefronts, or normalize product attributes across multiple suppliers.
HR & Recruitment. Parse resumes and extract structured candidate profiles, screen cover letters, generate interview question sets tailored to job descriptions, summarize employee feedback surveys, or classify internal knowledge base articles.
Legal & Finance. Summarize contract clauses, extract key terms and obligations, flag non-standard language in agreements, categorize expense reports, or generate structured abstracts from regulatory filings.
Education & Research. Summarize academic papers, extract citations and key findings, generate quiz questions from study materials, classify research topics, or transform lecture notes into structured outlines.
Official SDKs are available for PHP, Laravel, Python, and JavaScript/TypeScript. Browse all Custom Workflow SDK packages on GitHub.
Custom Workflows use the same credit-based billing system as every other SharpAPI endpoint. There is no extra charge, no separate pricing tier, no hidden fees. If you have credits, you can run workflows.
The feature is available on all plans, from the free tier up to enterprise. Scale and Enterprise plans include additional support for custom endpoint configuration, dedicated account management, and custom SLAs.
Custom Workflows is live in the SharpAPI Dashboard right now. Log in, click "Create Workflow," and have your first custom AI endpoint running in under a minute.
Whether you are building a document processing pipeline, adding AI-powered content analysis to your SaaS product, or just prototyping a new feature idea, Custom Workflows gives you the fastest path from concept to production API.
