Visma

Visma is a Nordic business-software group headquartered in Oslo, Norway, supplying cloud ERP, accounting, invoicing, payroll, HR and public-sector software to more than a million customers across Europe and Latin America. Its developer surface is federated across product lines rather than centralised: Visma.net ERP publishes a 511-operation OpenAPI 3.0 contract at api.finance.visma.net in service (client-credentials) and interactive (authorization-code) flavours; Bookkeeping & Invoicing/eAccounting and Cloud Payroll (Spiris, formerly Visma Spcs) publish OpenAPI 3.0 contracts at eaccountingapi.vismaonline.com and vlsapi.vismaonline.com; and Business NXT exposes a GraphQL API at business.visma.net. Identity is centralised on Visma Connect (connect.visma.com), an OpenID Connect provider advertising 129 scopes, with a second IdentityServer at identity.vismaonline.com for the Spiris product line. Visma ships two first-party remote MCP servers — Business NXT at mcp.business.visma.net and Spiris at mcp.spiris.se — both OAuth-protected and discoverable via RFC 9728.

Visma publishes 3 APIs on the APIs.io network: Visma.net ERP API, Bookkeeping & Invoicing / eAccounting API, and Cloud Payroll (Spiris Lon) API. Tagged areas include Accounting, Business Software, ERP, Enterprise, and Financial-Services.

The Visma catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Visma’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, engineering blog, authentication, and 35 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/visma: open an issue to ask a question, or submit a pull request to add artifacts.
