Making requests

All HoopAI API requests follow REST conventions. This guide covers the patterns you’ll use in every integration.

Base URL

https://services.leadconnectorhq.com

The base URL uses the LeadConnector domain. This is the API infrastructure that powers HoopAI — all data belongs to your HoopAI account.

Request structure

Every request needs the Authorization and Version headers:

curl -X GET "https://services.leadconnectorhq.com/{endpoint}" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Version: 2021-07-28" \
  -H "Content-Type: application/json"

Common parameters

Parameter	Description	Used in
`locationId`	Account ID (required for most endpoints)	Query string or body
`limit`	Number of results per page (default varies by endpoint)	Query string
`offset` / `page`	Pagination cursor	Query string

Pagination

Most list endpoints return paginated results. The response includes metadata about total results and how to fetch the next page.

{
  "contacts": [...],
  "meta": {
    "total": 342,
    "currentPage": 1,
    "nextPage": 2,
    "startAfter": 20,
    "startAfterId": "abc123"
  }
}

Offset-based pagination

# Page 1
GET /contacts/?locationId=LOC_ID&limit=20

# Page 2
GET /contacts/?locationId=LOC_ID&limit=20&startAfter=20

Cursor-based pagination

Some endpoints use cursor-based pagination with startAfterId:

# First page
GET /contacts/?locationId=LOC_ID&limit=20

# Next page (use the last item's ID)
GET /contacts/?locationId=LOC_ID&limit=20&startAfterId=abc123

Always check the meta object in the response for pagination details. If nextPage is null, you’ve reached the last page.

Filtering and searching

Many list endpoints support filtering via query parameters or a search body:

# Filter contacts by tag
GET /contacts/?locationId=LOC_ID&query=tag:lead

# Search contacts (POST)
POST /contacts/search
{
  "locationId": "LOC_ID",
  "filters": [
    { "field": "tags", "operator": "contains", "value": "lead" }
  ],
  "page": 1,
  "pageLimit": 20
}

Creating and updating resources

Use POST to create and PUT to update. Always send JSON bodies with the Content-Type: application/json header.

# Create a contact
curl -X POST "https://services.leadconnectorhq.com/contacts/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Version: 2021-07-28" \
  -H "Content-Type: application/json" \
  -d '{
    "locationId": "LOC_ID",
    "firstName": "Jane",
    "lastName": "Smith",
    "email": "jane@example.com",
    "phone": "+15551234567",
    "tags": ["lead", "website"]
  }'

Error handling

All errors return a consistent JSON structure:

{
  "statusCode": 422,
  "message": "Validation failed",
  "errors": [
    { "field": "email", "message": "Invalid email format" }
  ]
}

Status	Meaning	What to do
`400`	Bad request	Check request body and parameters
`401`	Unauthorized	Token missing, expired, or invalid — refresh it
`403`	Forbidden	Token lacks required scope
`404`	Not found	Resource doesn’t exist or wrong `locationId`
`422`	Validation error	Check the `errors` array for field-level details
`429`	Rate limited	Wait and retry with exponential backoff
`500`	Server error	Retry after a short delay

Rate limits

Scope	Limit
Per account	100 requests / 10 seconds
Token refresh	5 requests / minute

Rate limit headers are included in every response:

Header	Description
`X-RateLimit-Remaining`	Requests remaining in the current window
`X-RateLimit-Reset`	Unix timestamp when the limit resets

When you receive a 429 response, use exponential backoff:

async function fetchWithRetry(url, options, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    const response = await fetch(url, options);
    if (response.status !== 429) return response;

    const resetAt = response.headers.get('X-RateLimit-Reset');
    const waitMs = resetAt
      ? (parseInt(resetAt) * 1000) - Date.now()
      : Math.pow(2, i) * 1000;

    await new Promise(resolve => setTimeout(resolve, Math.max(waitMs, 1000)));
  }
  throw new Error('Max retries exceeded');
}
