Quick Start

Basic Request

GET /_api/web HTTP/1.1
Host: localhost:5000
Accept: application/json;odata=verbose
Authorization: Basic YWRtaW46cGFzc3dvcmQ=

JavaScript Example

fetch('http://localhost:5000/_api/web/lists', {
  headers: {
    'Accept': 'application/json;odata=verbose',
    'Authorization': 'Basic ' + btoa('admin:password')
  }
})
.then(response => response.json())
.then(data => console.log(data.d.results));

PowerShell Example

$headers = @{
    "Authorization" = "Basic " + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("admin:password"))
    "Accept" = "application/json;odata=verbose"
}

Invoke-RestMethod -Uri "http://localhost:5000/_api/web/lists" -Headers $headers

Limitations & Workarounds

❌ Not Supported

OData v4 Features: - $count=true (use OData v3 __count instead) - $search (use $filter with substringof) - $apply (use multiple queries)

Advanced Features: - Workflow REST APIs (deprecated in SharePoint) - Social feed APIs (use Microsoft Graph instead) - SharePoint Online-specific endpoints (Hub Sites, Compliance)

⚠️ Partial Support

Batch Requests: - $batch endpoint exists but has limited testing - Prefer individual requests for reliability

Navigation Properties: - Some complex $expand paths may not work - Use multiple requests if expansion fails

✅ Workarounds

Missing OData Features → Use SOAP:

# If REST query fails, use SOAP Lists service:
$svc = New-WebServiceProxy -Uri "http://localhost:5000/_vti_bin/lists.asmx?WSDL"
$items = $svc.GetListItems("Documents", $query, $viewFields, ...)

Complex Queries → Break into Multiple Requests:

// Instead of complex $expand:
const lists = await fetch('/_api/web/lists').then(r => r.json());
const items = await Promise.all(
  lists.d.results.map(list =>
    fetch(`/_api/web/lists(guid'${list.Id}')/items`).then(r => r.json())
  )
);

Error Handling

Error Response Format

{
  "error": {
    "code": "-1, System.ArgumentException",
    "message": {
      "lang": "en-US",
      "value": "List 'InvalidList' does not exist at site with URL 'http://localhost:5000'."
    }
  }
}

Common HTTP Status Codes

Code	Meaning	Common Cause
200	OK	Request succeeded
201	Created	Resource created successfully
400	Bad Request	Invalid request body or query
401	Unauthorized	Missing or invalid authentication
404	Not Found	List, item, or file not found
409	Conflict	Resource already exists (create)
412	Precondition Failed	IF-MATCH etag mismatch
500	Internal Server Error	Server error (check logs)

---

Best Practices

1. Use $select for Better Performance

Only request fields you need:

// ❌ Bad - returns all fields
fetch('/_api/web/lists/getbytitle("Documents")/items')

// ✅ Good - only returns needed fields
fetch('/_api/web/lists/getbytitle("Documents")/items?$select=Title,Created')

2. Use Batch Requests for Multiple Operations

Reduce round-trips with batch requests:

POST /_api/$batch
Content-Type: multipart/mixed; boundary=batch_abc123

--batch_abc123
Content-Type: application/http
Content-Transfer-Encoding: binary

GET /_api/web/lists HTTP/1.1
Accept: application/json

--batch_abc123--

3. Handle Pagination for Large Results

Use $top and $skip for pagination:

async function getAllItems(listTitle) {
  const pageSize = 100;
  let skip = 0;
  let allItems = [];

  while (true) {
    const url = `/_api/web/lists/getbytitle('${listTitle}')/items?$top=${pageSize}&$skip=${skip}`;
    const response = await fetch(url).then(r => r.json());
    const items = response.d.results;

    if (items.length === 0) break;

    allItems.push(...items);
    skip += pageSize;
  }

  return allItems;
}

4. Cache Form Digest

Cache form digest to avoid unnecessary requests:

let formDigestValue = null;
let formDigestExpiry = null;

async function getFormDigest() {
  if (formDigestValue && formDigestExpiry > Date.now()) {
    return formDigestValue;
  }

  const response = await fetch('/_api/contextinfo', { method: 'POST' })
    .then(r => r.json());

  formDigestValue = response.d.GetContextWebInformation.FormDigestValue;
  formDigestExpiry = Date.now() + 1800000; // 30 minutes

  return formDigestValue;
}
