Validation status

Implemented · fixture tested.

Implementation is checked against provider-shaped fixtures for every action, authentication failures, rate limits, pagination and duplicate safety. Provider sandbox and authorised account validation are recorded separately when credential-backed runs are completed.

Authentication

BILL developer key with an AP & AR sync token (or user sign-in)

Plans and access

BILL Accounts Payable and Accounts Receivable plans with a developer key from the BILL developer program. An AP & AR sync token (recommended) can manage vendors, customers, bills, invoices and classifications but cannot pay, void or send; user logins follow the user's role.

Test environment

BILL sandbox organizations use gateway.stage.bill.com with a sandbox developer key.

Rate limits

20,000 requests per developer key per hour, 200 sign-ins per hour, and 3 concurrent requests per developer key and organization (BDC_1144 and BDC_1322).

Pagination

max (up to 100) with nextPage tokens; filters and sort are fixed by the first request.

Provider events

BILL webhook subscriptions for vendor, bill, invoice and payment events. Nexra event triggers are not yet available; flows run on demand or on a schedule.

Before you build a flow

  • Payments are read only: Nexra never creates, schedules, cancels or voids payments, and never records payments.
  • Bills are created unpaid without approvals; invoices are created without emailing (processingOptions.sendEmail is false).
  • Sessions expire after 35 minutes idle (48 hours for sync tokens); Nexra signs in again after a 401.
  • Archive, restore, bulk endpoints, vendor bank accounts, sending invoices and MFA flows are not automated.
  • Rate-limit errors are returned as BILL error codes; Nexra treats them by HTTP status.
  • Department and location classifications are read only in this adapter.
  • BILL has no idempotency key; uncertain creates are not repeated automatically. Duplicate vendor invoice numbers on bills are rejected by BILL.

Developer reference

  1. Create the BILL Holdings credentials described above with the narrowest permissions your flows need.
  2. In Nexra, open Connect, then Connections, then New connection, choose BILL, enter its settings and credentials, and tick only the write actions you need. Connection guide
  3. Test the connection, then use its actions as flow sources and destinations. Flow guide
