Apify Integration Development

Design and build an Apify integration for a company's product, with minimal help from Apify. This skill covers every integration shape Apify supports - workflow-automation apps, AI agent plugins (coding agents and harnesses), AI framework packages, and direct application clients - so a partner team can ship a first-class Apify integration end to end. The cross-cutting rules below apply to all of them, and one category-specific reference file carries the rest.

> Building an official integration? Once you publish it, contact [email protected] so the Apify team can review, test, and validate your integration for official validation. Publication alone does not establish endorsement. Apify can check the capability surface, cost controls, error handling, and attribution headers, and help you close any gaps.

Step 0 - Learn the Apify model first (required)

Before designing anything, fetch and read https://apify.com/agents.md. It is the canonical quickstart for AI agents and the single source of truth for vocabulary, the run flow, and the cost rule. If the fetch fails, the mini-glossary below keeps the skill usable.

Apify vocabulary (always written with a capital A on the platform):

• Actor - a serverless cloud program that takes JSON input, performs a task, and produces structured output. Not an AI agent.
• Actor Run - one execution of an Actor. Each run has its own dataset, key-value store, and request queue, and ends in a terminal status (SUCCEEDED, FAILED, TIMED-OUT, ABORTED).
• Dataset - append-only structured storage for a run's results. An Actor call returns the dataset ID, not its contents.
• Key-Value Store - unstructured/file storage (screenshots, HTML, OUTPUT).
• Actor Task - a saved, parameterized configuration for running an Actor.
• Apify Store - the marketplace of Actors at https://apify.com/store.md.
• Apify Console - the web UI at https://console.apify.com.
• Compute Unit (CU) - billing unit: memory (GB) x duration (hours).

Further terms (build, standby, request queue, proxy, pricing models): https://docs.apify.com/llms.txt.

Use Apify MCP for live context while planning

The Apify MCP server is the fastest way to research Actors, schemas, pricing, and docs during integration design. See https://docs.apify.com/integrations/mcp (append .md for a markdown version).

If Apify MCP tools are already available in this environment, use them:

• search-actors - find Actors by platform/product keyword (search by product name, not end goal).
• fetch-actor-details - read an Actor's input schema, output format, README, and pricing before you encode its shape into the integration.
• search-apify-docs / fetch-apify-docs - pull contextual documentation pages.

The anonymous discovery subset (search-actors, fetch-actor-details, search-apify-docs, fetch-apify-docs) works without an account, so you can research even before the developer has connected their token.

Pick your integration shape

Read exactly one reference file based on the product you are integrating into. Each reference carries the category-specific UX design, a canonical capability matrix, and a definition-of-done checklist.

| Product shape | Examples | Read |

|---|---|---|

| Workflow automation platform | Zapier, n8n, Make, Pipedream, Activepieces | references/workflow-automation.md |

| AI agent plugin (coding agent or harness) | Cursor, Claude Code, Codex, GitHub Copilot (coding agents); OpenClaw-style runtimes, Hermes-style harnesses (harnesses) | references/ai-harness-plugin.md |

| AI framework package (PyPI/npm for LLM frameworks) | LangChain, LlamaIndex, Haystack, Vercel AI SDK | references/ai-framework-package.md |

| Application integration (direct client) | A backend service, scheduled job, product feature calling Actors via apify-client or REST | references/sdk-integration.md |

Paths are relative to this skill folder. If your product spans two shapes (e.g. an AI harness built on top of a framework package), read both - the rules compose. The AI agent plugin reference covers two approaches with different trade-offs: a lightweight skills + MCP bundle for skills/MCP-aware coding agents, and a custom tool-registry plugin for OpenClaw/Hermes-style harnesses.

Cross-cutting design rules (true for every integration type)

These invariants were extracted from every existing Apify integration. Apply them regardless of shape.

Vocabulary mirroring

Model the integration's resources on Apify's domain (Actor / Run / Dataset / KV Store / Task). Users coming from Apify Console should find the same concepts under the same names.

Asynchronous run flow with bounded polling

Actors can run for seconds to hours. Use the asynchronous flow, never the 300-second synchronous endpoint for anything but short jobs:

POST /v2/actors/{actorId}/runs            -> start, return runId
GET  /v2/actor-runs/{runId}               -> poll until terminal status
GET  /v2/datasets/{datasetId}/items       -> fetch results on SUCCEEDED

Polling must be bounded: use the run's own timeoutSecs plus a grace buffer, with an absolute ceiling fallback. Never while (true). On a non-terminal status, surface the run ID so the user/agent can poll again or inspect the failure.

Cost is first-class

Every path that starts a run must expose a cost control. The canonical control is maxTotalChargeUsd (caps the run's total charge on most pricing models) and maxItems (caps billed items on pay-per-result Actors). Send them as options / query parameters, never as Actor input - inside input they are either an Actor-declared field or simply invalid. 0 / empty / null means *no limit*. For LLM-facing integrations, the ceilings are developer-controlled; an LLM cannot widen them.

Attribution headers

Stamp an integration header on every outbound request so Apify can attribute traffic: x-apify-integration-platform: <your-platform>. When a request is driven by an AI tool (not a human in a UI), also send x-apify-integration-ai-tool: true. If the integration was built using this skill, add x-apify-integration-origin: apify-integration-development-skill so Apify can distinguish skill-generated integrations from custom ones. One line, big telemetry payoff.

Authentication

• Browser / consumer-facing (a human completes a sign-in): OAuth2 with PKCE. Do not ask for raw tokens.
• Headless / server / CI (no human present): API token as Authorization: Bearer <APIFY_TOKEN>, stored in an env var or secret manager, never hardcoded or logged.

Both paths are real - pick by who is present at auth time, not by which is easier.

Centralized HTTP layer

One base-URL constant, shared between credentials and the HTTP layer. Retries with exponential backoff on 429 and 5xx. Never retry non-idempotent POST /runs on network errors - a duplicate Actor run is a real, billed, side-effecting operation. This is the single most important correctness invariant in the HTTP layer.

Error taxonomy

Map Apify errors to the host platform's error categories (retryable vs auth vs permanent). Surface actionable API error details after redacting credentials, input secrets, personal data and sensitive logs. For permission-approval failures (a full-permission Actor needs explicit approval), include the approval URL after validating it is an absolute HTTPS URL on an explicitly trusted Apify Console host. For LLM consumers, return errors as data (JSON error objects), never as raised exceptions - the model needs something to read and reason about.

Webhooks over polling for run-finished events

When the host supports inbound webhooks, register an Apify webhook scoped to actorId or actorTaskId with the terminal statuses the user picked. Make registration idempotent (a re-activated workflow should not create duplicate webhooks), persist the webhook ID so deactivation can clean it up, and always provide sample/fallback data so users can test the trigger without waiting for a real run.

Generate from OpenAPI where the host allows it

If the host platform can generate UI fields from an OpenAPI spec, use Apify's spec (https://apify.com/openapi.json) and a tag allowlist. Hand-write only what the spec cannot express: convenience wrappers, bill-cap fields, lean AI-tool output contracts.

High-level convenience operations alongside generic runs

Generic "run Actor" serves power users. Add a few opinionated, high-level actions for the common case (e.g. "Scrape single URL" wrapping a content scraper with maxCrawlDepth: 0, maxResults: 1) so non-power users get a 2-field form instead of a full Actor configuration. Validate the URL *before* starting a paid run.
