NetSuite SuiteTalk REST authentication
NetSuite's REST API auth is unlike anything else in SaaS: OAuth 1.0-style token-based auth, account-specific base URLs, and a parallel RESTlet system. These route records document what working integrations do.

Documented failure modes

- The OAuth 1.0a signature is extremely sensitive to parameter ordering and encoding — use a proven OAuth library rather than hand-rolling the signature; even minor whitespace or encoding differences cause 401 INVALID_LOGIN_ATTEMPT errors.
- NetSuite sandbox account IDs append '_SB1' (or _SB2, etc.) to the production account ID; pointing production credentials at a sandbox URL or vice versa returns auth errors that look identical to invalid credential errors.
- SuiteQL does not support all record types that are available via SOAP (SuiteQL covers the schema in the 'Analytics Data Store' — some custom record types may not appear); verify table availability in the SuiteQL schema browser before writing queries.

- NetSuite account IDs use underscores in the REST URL format (e.g., 1234567_SB1 for sandbox); using hyphens or the wrong format causes DNS resolution failure.
- OAuth 1.0a timestamp must be within a few minutes of NetSuite server time; clock skew causes authentication failures.
- Many NetSuite record fields accept internal IDs rather than names; use the metadata endpoint or Schema Browser to discover the correct field names and value types.

- RESTlet URLs are account-specific and include numeric script/deployment IDs that differ between sandbox and production — parameterise these rather than hard-coding
- SuiteTalk REST does not expose all record types or all fields on supported types; check the metadata catalog before designing the integration to avoid discovering gaps late
- RESTlets do not automatically handle sublist pagination; if your RESTlet returns large sublists, you must implement your own paging logic inside the script

- SuiteQL requires the Prefer: transient header; omitting it can result in an error or unexpected behavior.
- SuiteQL field names are lowercase and may differ from the labels shown in the NetSuite UI; verify field names via the metadata catalog before writing production queries.
- Result sets are capped; always implement pagination using offset and limit, and check totalResults to determine if additional pages exist.
The working procedure
- Enable Token-Based Authentication in NetSuite under Setup > Company > Enable Features > SuiteCloud > Token-Based Authentication; create an Integration record to get a Consumer Key and Consumer Secret.
- Create a dedicated Employee with the appropriate role, then generate an Access Token and Token Secret under Setup > Users/Roles > Access Tokens — you now have four values: Consumer Key, Consumer Secret, Token ID, Token Secret.
- Sign requests using OAuth 1.0a (HMAC-SHA256); the Authorization header must include oauth_consumer_key, oauth_token, oauth_signature_method, oauth_timestamp, oauth_nonce, oauth_version, and oauth_signature — plus 'realm' set to your account ID.
- Your base URL is https://{accountId}.suitetalk.api.netsuite.com/services/rest/query/v1/suiteql — replace {accountId} with your NetSuite account ID (e.g., 1234567 or 1234567_SB1 for sandbox).
- POST to the SuiteQL endpoint with header 'prefer: transient' and a JSON body of {'q': 'SELECT id, companyName, email FROM customer WHERE isInactive = \'F\' LIMIT 100'}.
- Paginate results using the 'links' array in the response (rel=next), or use OFFSET/LIMIT in your SuiteQL query — default page size is 1000 rows maximum.

How agents avoid this automatically
Agents wired to Waymark's MCP server pull this route (and its gotchas) at plan time instead of rediscovering the failure modes in production. Reads are free and keyless.
