Webflow SDK Patterns
Overview
Production-ready patterns for the webflow-api SDK (v3.x). Covers singleton client,
typed error handling, pagination, raw response headers, and multi-tenant factory.
Prerequisites
webflow-api v3.x installed
TypeScript 5+ project
Familiarity with async/await and the Webflow Data API v2
Instructions
Pattern 1: Singleton Client with Configuration
import { WebflowClient } from "webflow-api" ;
interface WebflowConfig {
accessToken : string ;
timeout ?: number ;
maxRetries ?: number ;
}
let instance : WebflowClient | null = null ;
export function getWebflowClient (config ?: Partial <WebflowConfig > ): WebflowClient {
if (!instance) {
const token = config?.accessToken || process.env .WEBFLOW_API_TOKEN ;
if (!token) throw new Error ("WEBFLOW_API_TOKEN required" );
instance = new WebflowClient ({
: token,
...(config?. && { : config. }),
...(config?. !== && { : config. }),
});
}
instance;
}
( ): {
instance = ;
}

Pattern 2: Typed Error Handling The SDK throws WebflowError subclasses. Handle them by type:
import { WebflowClient } from "webflow-api" ;
async function safeWebflowCall<T>(
operation : () => Promise <T>,
context : string
): Promise <{ data : T | null ; error : string | null }> {
try {
const data = await operation ();
return { data, error : null };
} catch (err : any ) {
const statusCode = err.statusCode || err.status ;
const message = err.message || String (err);
console .error (`[Webflow] ${context} failed:` , {
status : statusCode,
message,
body : err.body ,
});
switch (statusCode) {
case 401 :
console .error ("Token invalid or revoked. Rotate token." );
break ;
case 403 :
console .error ("Missing required scope. Check token scopes." );
break ;
case 404 :
console .error ("Resource not found. Verify IDs." );
break ;
case 409 :
console .error ("Conflict — item may already exist with this slug." );
break ;
case 429 :
console .error ("Rate limited. SDK will auto-retry with backoff." );
break ;
default :
if (statusCode >= 500 ) {
console .error ("Webflow server error. Retry later." );
}
}
return { data : null , error : message };
}
}
const { data : sites, error } = await safeWebflowCall (
() => webflow.sites .list (),
"sites.list"
);
Pattern 3: Pagination Helper Webflow v2 uses offset-based pagination. Iterate through all pages:
interface PaginatedResult <T> {
items : T[];
pagination : { limit : number ; offset : number ; total : number };
}
async function fetchAllItems<T>(
fetcher : (offset : number , limit : number ) => Promise <PaginatedResult <T>>,
pageSize = 100
): Promise <T[]> {
const allItems : T[] = [];
let offset = 0 ;
while (true ) {
const result = await fetcher (offset, pageSize);
allItems.push (...result.items );
if (allItems.length >= result.pagination .total ) break ;
offset += pageSize;
}
return allItems;
}
const allItems = await fetchAllItems ((offset, limit ) =>
webflow.collections .items .listItems (collectionId, { offset, limit })
.then (res => ({
items : res.items || [],
pagination : res.pagination || { limit, offset, total : 0 },
}))
);
Pattern 4: Raw Response Access (Headers) Access rate limit headers using .withRawResponse():
async function getWithRateLimitInfo (siteId : string ) {
const response = await webflow.sites .get (siteId)
;
const rawFetch = await fetch (
`https://api.webflow.com/v2/sites/${siteId} ` ,
{
headers : {
Authorization : `Bearer ${process.env.WEBFLOW_API_TOKEN} ` ,
"Content-Type" : "application/json" ,
},
}
);
const rateLimitRemaining = rawFetch.headers .get ("X-RateLimit-Remaining" );
const rateLimitLimit = rawFetch.headers .get ("X-RateLimit-Limit" );
const retryAfter = rawFetch.headers .get ("Retry-After" );
console .log (`Rate limit: ${rateLimitRemaining} /${rateLimitLimit} ` );
return rawFetch.json ();
}
Pattern 5: Multi-Tenant Factory For apps serving multiple Webflow workspaces:
const clients = new Map <string , WebflowClient >();
export function getClientForTenant (tenantId : string ): WebflowClient {
if (!clients.has (tenantId)) {
const token = getTenantToken (tenantId);
clients.set (
tenantId,
new WebflowClient ({ accessToken : token })
);
}
return clients.get (tenantId)!;
}
export function rotateTenantToken (tenantId : string , newToken : string ): void {
clients.set (
tenantId,
new WebflowClient ({ accessToken : newToken })
);
}
Pattern 6: Bulk Operations Helper The CMS bulk endpoints accept up to 100 items per request:
async function bulkCreateItems (
collectionId : string ,
items : Array <{ fieldData: Record<string , any >; isDraft?: boolean }>,
batchSize = 100
): Promise <string []> {
const createdIds : string [] = [];
for (let i = 0 ; i < items.length ; i += batchSize) {
const batch = items.slice (i, i + batchSize);
const result = await webflow.collections .items .createItemsBulk (
collectionId,
{ items : batch }
);
if (result.items ) {
createdIds.push (...result.items .map (item => item.id !));
}
console .log (`Created batch ${Math .floor(i / batchSize) + 1 } : ${batch.length} items` );
}
return createdIds;
}
Pattern 7: Zod Validation for API Responses import { z } from "zod" ;
const WebflowSiteSchema = z.object ({
id : z.string (),
displayName : z.string (),
shortName : z.string (),
lastPublished : z.string ().nullable (),
customDomains : z.array (z.object ({
url : z.string (),
})).optional (),
});
const WebflowCollectionItemSchema = z.object ({
id : z.string (),
isDraft : z.boolean (),
isArchived : z.boolean (),
createdOn : z.string (),
lastUpdated : z.string (),
fieldData : z.record (z.unknown ()),
});
async function getValidatedSite (siteId : string ) {
const site = await webflow.sites .get (siteId);
return WebflowSiteSchema .parse (site);
}
Output
