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

SAP Business One user name and password (Service Layer session)

Plans and access

SAP Business One 10.0 (SAP HANA or Microsoft SQL Server) with the Service Layer installed; OData v4 (/b1s/v2) is used because OData v3 is deprecated as of FP 2405. Calls run as the signed-in SAP Business One user and follow that user's authorisations and licence.

Test environment

Use a test company database (for example the demo database) on a partner or customer Service Layer.

Rate limits

No published request limit; throughput depends on the Service Layer cluster. Sessions time out after the configured SessionTimeout (30 minutes by default).

Pagination

Prefer: odata.maxpagesize (up to 100 here) with @odata.nextLink $skip paging.

Provider events

Service Layer has no outbound webhooks for document events in the documented API; SAP Business One integration framework or add-ons are used instead. Nexra event triggers are not yet available; flows run on demand or on a schedule.

Before you build a flow

  • The Service Layer must be reachable over HTTPS on port 443; Nexra does not call custom ports such as the default 50000.
  • AR and AP invoices are written only as drafts (Drafts with DocObjectCode oInvoices or oPurchaseInvoices); adding, posting, cancelling and closing documents are not automated.
  • Journal entries, payments, credit notes and deliveries are read only because they post to the ledger immediately.
  • Document updates change header fields only; line changes, deletes and Close or Cancel actions are intentionally excluded.
  • UpdateDate has day granularity, so incremental reads repeat the boundary day; deduplicate on the record ID.
  • Business partner and item writes cover the common fields and user-defined fields are returned but not written.
  • The Service Layer API reference is published as an interactive page; endpoints and fields follow the SAP 'Working with SAP Business One Service Layer' guide (v1.28) and the BusinessPartner, Item and Document metadata types.

Developer reference

  1. Create the SAP credentials described above with the narrowest permissions your flows need.
  2. In Nexra, open Connect, then Connections, then New connection, choose SAP Business One, 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
