faqs:
  - question: "Is there a public API for affiliate blog publishing?"
    answer: "Yes. UseArticle exposes a public REST API at https://app.usearticle.com/api/v1 with endpoints for sites, products, posts, and automations. Authenticated via Bearer token from the dashboard, the API mirrors every in-product action, so anything you can do in the UseArticle UI you can do programmatically. Plans Base, Unlimited, and BYOK lifetime all include API access; the Free plan does not."
  - question: "What can I build with an affiliate blog API?"
    answer: "Common builds include: programmatic site creation for agencies managing client affiliate sites, bulk product import from external sources (Google Sheets, Airtable, your own CRM), custom AI generation orchestrators that call the post-generation endpoint with niche-specific prompts, scheduled automation creators that respond to inventory changes, and integrations with non-affiliate tools like Slack notifications, analytics warehouses, or email reporting."
  - question: "How does API authentication work for affiliate blog platforms?"
    answer: "UseArticle uses Bearer token authentication. You generate an API key in the dashboard under Automation → API Keys, then send it as `Authorization: Bearer ua_live_xxx` on every request. Keys are tied to your account's subscription status - lapsed accounts return HTTP 402 Payment Required so your tooling can prompt for resubscription. Failed auth returns 401 (invalid key) or 403 (key valid but feature blocked)."
  - question: "What programming language do I need for the affiliate blog API?"
    answer: "Any language that can make HTTP requests. The API is standard REST with JSON payloads, so it works equally well with cURL, Python, Node.js, Go, Ruby, PHP, and any other modern language. Most affiliate marketers use Python or Node.js because of the rich ecosystems of AI and automation libraries. Non-coders typically use no-code tools like n8n, Make, or Zapier to interact with the API without writing code."
  - question: "What rate limits apply to affiliate blog APIs?"
    answer: "UseArticle's API rate limits are governed by your subscription's automation cap (Base 2 active automations, Unlimited 5, BYOK 5) and by sensible per-endpoint limits to prevent abuse. For most legitimate affiliate workflows - including agencies managing 20-50 sites - the limits are not constraining. If you need higher limits for a specific use case, the team is reachable for capacity discussions."
  - question: "Can I use the affiliate blog API to migrate from WordPress?"
    answer: "Yes. A typical migration script reads existing WordPress posts via the WordPress REST API, transforms each one into a UseArticle post format, and POSTs to the UseArticle posts endpoint. For sites with hundreds of articles, this turns a multi-week migration into a few hours of script execution. Reach out for migration assistance if you are considering moving a high-traffic site."

The affiliate marketers building defensible businesses in 2026 are not just publishing content - they are building systems. APIs are what turn a one-person affiliate operation into a programmable engine. With a public affiliate blog API, you can manage sites, products, posts, and automations the same way you would manage any other piece of your stack: with code, version control, and CI/CD if you want.

This guide covers what an affiliate blog API actually unlocks, how UseArticle's API works specifically, and the practical builds that benefit most from API-first affiliate publishing.

## What an affiliate blog API is and why it matters

An affiliate blog API is a programmatic interface to a content platform's core operations: creating sites, managing products, generating posts, and scheduling automations. Without an API, you can only do these things one at a time through a web interface. With an API, you can do them in batches, on schedules, or in response to triggers in your other systems.

The shift from "click in the dashboard" to "call an API" matters when you cross certain thresholds:

- **Multiple sites.** Managing 5+ affiliate sites manually is painful. APIs let you create, configure, and update sites in batches.
- **Programmatic content sourcing.** When products come from external sources (your CRM, scraped feeds, partner lists), an API connects them directly to your publishing platform.
- **Custom orchestration.** When your generation logic is more complex than what the platform's UI supports, an API gives you raw access to the building blocks.
- **Multi-tool integration.** When affiliate publishing is part of a larger pipeline (analytics, email, Slack), the API is how you connect it.

For single-site affiliate marketers running standard workflows, the platform's UI is enough. For everyone scaling beyond that, the API earns its keep.

## UseArticle's affiliate blog API

UseArticle exposes a comprehensive public REST API. The full reference is at [the integrations docs](/integrations/n8n) and the in-product API Docs tab.

### Base URL and authentication

```
https://app.usearticle.com/api/v1
```

Send your API key as a Bearer token on every request:

```http
Authorization: Bearer ua_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```

Generate the key in the UseArticle dashboard under Automation → API Keys.

### Authentication response codes

| Status | Meaning |
| --- | --- |
| 401 | Missing or invalid API key |
| 402 | Key valid but no active subscription |
| 403 | Authenticated but blocked by a feature limit |

Handle 402 specifically - it is your signal to prompt the user to resubscribe.

### Resource model

The API exposes four core resources:

1. **Sites** - your affiliate websites (`GET /sites`, `POST /sites`, `PATCH /sites/{id}`)
2. **Products** - products attached to a site (`GET /sites/{id}/products`, `POST /sites/{id}/products`)
3. **Posts** - generated affiliate articles (`POST /sites/{id}/posts`, `PATCH /posts/{id}`)
4. **Automations** - scheduled post generation (`POST /automations`, `PATCH /automations/{id}`)

The `POST /sites/{id}/posts` endpoint is where the real magic happens - asynchronously generates a structured affiliate post (review, comparison, buying guide, etc.) and returns a postId you can poll.

## Practical builds that benefit from API-first affiliate publishing

### Build 1: Agency multi-site management

If you run an affiliate agency with 10+ client sites, the API turns a multi-day onboarding process into a 5-minute script run. Programmatically create the site, import the client's product catalog from their CRM, configure their automation schedule, and deliver a working affiliate site to the client without touching the UseArticle UI.

```python
import requests

API_BASE = "https://app.usearticle.com/api/v1"
HEADERS = {"Authorization": "Bearer ua_live_xxx", "Content-Type": "application/json"}

def onboard_client(client_name, subdomain, product_urls):
    site = requests.post(f"{API_BASE}/sites", headers=HEADERS, json={
        "name": client_name,
        "subdomain": subdomain,
        "siteType": "affiliate"
    }).json()

    for url in product_urls:
        requests.post(f"{API_BASE}/sites/{site['id']}/products",
                      headers=HEADERS, json={"productUrl": url})

    return site
```

### Build 2: Bulk product import from a Google Sheet

Affiliate marketers who curate product lists in Google Sheets benefit from a one-script bulk import. The flow: read the sheet, POST each row to the products endpoint, log results back to the sheet for tracking.

This is the kind of workflow that runs equally well in Python, Node.js, or no-code tools like n8n with the Google Sheets and HTTP Request nodes.

### Build 3: Custom AI orchestration

Some affiliate operators want more control over generation than the platform UI offers - custom prompts, niche-specific tones, multi-step generation pipelines. The `POST /sites/{id}/posts` endpoint accepts a `customInstructions` field and returns the postId for polling, so you can build orchestration layers on top:

```python
def generate_post(site_id, product_id, template_type, custom_instructions):
    response = requests.post(
        f"{API_BASE}/sites/{site_id}/posts",
        headers=HEADERS,
        json={
            "templateType": template_type,
            "productIds": [product_id],
            "tone": "professional",
            "wordCount": 2000,
            "customInstructions": custom_instructions
        }
    )
    return response.json()["postId"]
```

Layer your own logic on top: A/B testing different tones, generating 3 variants and picking the best, or chaining post generation with social syndication.

### Build 4: Scheduled automation lifecycle management

Running 5 active automations is the cap on Unlimited. With the API, you can rotate which 5 are active based on business logic: pause comparison automation during seasonal peaks for review automation, automatically resume after the peak ends, swap automations based on inventory or commission rate changes.

```bash
curl -X PATCH https://app.usearticle.com/api/v1/automations/{automationId} \
  -H "Authorization: Bearer ua_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{ "isActive": false }'
```

### Build 5: Cross-platform integration

Use the API to connect affiliate publishing to the rest of your stack: send Slack notifications when posts publish, push published posts to a data warehouse for analytics, syndicate to social media after each publish, or trigger email newsletter inclusions for top-performing posts.

This is where n8n shines - the visual workflow builder lets you wire up these integrations without writing code, while still using the same UseArticle API endpoints.

## Best practices for affiliate API integrations

**Use the API key from a single source.** Do not paste the same key in 10 places. Centralize it in a credential store (your dotenv file, n8n credentials, your secrets manager) and reference it.

**Handle the 402 response specifically.** If a customer's subscription lapses, the API returns 402 with a clear error message. Your tooling should surface this so the user can resubscribe rather than just seeing a generic error.

**Respect async generation.** The post generation endpoint is async - it returns a postId quickly, and the actual generation completes in the background. Poll `GET /posts/{postId}` for status rather than expecting an immediate completion.

**Log everything.** Affiliate publishing is high-volume by design. Logs are essential for debugging when something goes wrong at 2 AM.

**Rate limit yourself.** Even within platform limits, implement client-side rate limiting so a runaway script does not flood the API.

## When you should not use the API

The API earns its keep at scale. For single-site affiliate marketers running standard workflows, the UseArticle web interface is faster and simpler. The API path makes sense when:

- You manage 5+ affiliate sites
- You have product data in external systems (Sheets, Airtable, your CRM)
- You want custom orchestration beyond platform defaults
- You are integrating affiliate publishing into a larger pipeline

For everyone else, the in-product UI handles the same operations more conveniently.

## Final word

The affiliate blog API is the building block for the next generation of affiliate publishing operations. The marketers who treat affiliate sites as software systems - versioned, programmable, integrated - will outscale the ones still clicking through dashboards. Whether you build with raw API calls, no-code tools like n8n, or AI agents that orchestrate the full pipeline, the API is what unlocks the leverage. Get the key, write the first script, and start composing.
