Wix API Core - Direct REST API Calls

Overview

This skill provides foundational patterns for making direct Wix REST API calls without using MCP tools. All requests use curl commands with proper authentication and headers.

Authentication & Headers

Required Configuration

• App ID: df7c18eb-009b-4868-9891-15e19dddbe67 (hard-coded)
• API Key: ${API_KEY} (environment variable)
• Site ID: ${SITE_ID} (environment variable)

Header Patterns

Site-level requests (most common):

-H "Authorization: ${API_KEY}"
-H "wix-site-id: ${SITE_ID}"
-H "Content-Type: application/json"

Account-level requests (rare):

-H "Authorization: ${API_KEY}"
-H "wix-account-id: ${ACCOUNT_ID}"
-H "Content-Type: application/json"

Important Rules

• Use wix-site-id OR wix-account-id, NOT both
• Most APIs operate at site level
• Site-level calls only work with keys from the site owner's account
• All POST/PATCH requests require Content-Type: application/json

Base URLs

Wix Stores Catalog V1 (Current)

https://www.wixapis.com/stores/v1/
https://www.wixapis.com/stores-reader/v1/

Wix Stores Catalog V2

https://www.wixapis.com/stores/v2/

Wix Stores Catalog V3 (Preview, Q4 2025)

https://www.wixapis.com/stores/v3/

Note: Each site supports either V1 or V3, not both. Use Catalog Versioning API to determine which version a site uses.

Common Request Patterns

GET Request

curl -X GET "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Accept: application/json"

POST Request with Query

curl -X POST "https://www.wixapis.com/stores/v1/products/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "query": {
    "filter": "{\"visible\": true}",
    "paging": {"limit": 50, "offset": 0}
  }
}'

PATCH Request (Update)

curl -X PATCH "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "product": {
    "name": "Updated Product Name",
    "price": 29.99
  }
}'

POST Request (Bulk Operation)

curl -X POST "https://www.wixapis.com/stores/v1/bulk/products/update" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "set": [
    {
      "id": "product-1",
      "property": "visible",
      "value": true
    }
  ]
}'

Pagination

Standard Pagination Pattern

curl -X POST "https://www.wixapis.com/stores/v1/products/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "query": {
    "paging": {
      "limit": 100,
      "offset": 0
    }
  }
}'

Response includes pagination metadata:

{
  "products": [...],
  "metadata": {
    "count": 100,
    "offset": 0,
    "total": 450
  }
}

Iterate through pages:

• First page: "offset": 0
• Second page: "offset": 100
• Third page: "offset": 200
• Continue until offset + count >= total

Filtering & Sorting

Filter Syntax

Filters use JSON string format inside query:

-d '{
  "query": {
    "filter": "{\"price\": {\"$gte\": 10, \"$lte\": 100}}"
  }
}'

Common filter operators:

• $eq - equals
• $ne - not equals
• $gt - greater than
• $gte - greater than or equal
• $lt - less than
• $lte - less than or equal
• $in - value in array
• $and - logical AND
• $or - logical OR

Sort Syntax

-d '{
  "query": {
    "sort": "{\"price\": \"asc\"}",
    "paging": {"limit": 50}
  }
}'

Sort directions:

• "asc" - ascending
• "desc" - descending

Error Handling

Standard HTTP Status Codes

• 200 - Success
• 400 - Bad Request (invalid parameters)
• 401 - Unauthorized (invalid API key)
• 403 - Forbidden (insufficient permissions)
• 404 - Not Found (resource doesn't exist)
• 429 - Too Many Requests (rate limit)
• 500 - Internal Server Error

Error Response Format

{
  "error": {
    "code": "INVALID_ARGUMENT",
    "message": "Product ID is required",
    "details": {
      "applicationError": {
        "description": "Product ID cannot be empty",
        "code": "MISSING_REQUIRED_FIELD"
      }
    }
  }
}

Error Handling Pattern

response=$(curl -s -w "\n%{http_code}" -X POST "https://www.wixapis.com/stores/v1/products/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"query": {}}')

http_code=$(echo "$response" | tail -n1)
body=$(echo "$response" | sed '$d')

if [ "$http_code" -ge 400 ]; then
  echo "Error: HTTP $http_code"
  echo "$body" | jq '.error'
  exit 1
fi

echo "$body" | jq '.'

Rate Limits

Wix API Rate Limits:

• Standard tier: 50 requests/second
• Burst capacity: 100 requests
• Per-site limits apply to site-level calls
• Per-account limits apply to account-level calls

Best Practices:

• Implement exponential backoff on 429 errors
• Use bulk endpoints when updating multiple resources
• Cache responses when appropriate
• Monitor X-RateLimit-* headers in responses

Common Response Structures

Single Resource Response

{
  "product": {
    "id": "abc123",
    "name": "Product Name",
    "price": 29.99,
    "visible": true
  }
}

Collection Response

{
  "products": [
    {
      "id": "abc123",
      "name": "Product 1"
    }
  ],
  "metadata": {
    "count": 1,
    "offset": 0,
    "total": 1
  }
}

Bulk Operation Response

{
  "bulkActionMetadata": {
    "totalSuccesses": 10,
    "totalFailures": 0,
    "undetailedFailures": 0
  },
  "results": [
    {
      "itemMetadata": {
        "id": "product-1",
        "originalIndex": 0,
        "success": true
      }
    }
  ]
}

Testing API Calls

Test Connection

  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"query": {"paging": {"limit": 1}}}'

Expected response: HTTP 200 with product data

Validate Permissions

# Test read permission
curl -X GET "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}"

# Test write permission
curl -X PATCH "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"product": {"name": "Test Update"}}'
