Altitude Software

Altitude Software is a contact center and unified customer interaction (uCI) software company founded in 1993 and headquartered in Lisbon, Portugal. Its flagship Altitude uCI suite provides omnichannel contact center capabilities — inbound/outbound campaigns, IVR and self-service, routing, dialer, recording and quality management, and CRM/ERP integration — with the Altitude uAgent SDK exposing Java, C/C++, .NET, SOAP, XML-RPC and web-service APIs for on-premises and cloud deployments. Altitude Software was a portfolio company of Insight Partners and was acquired by Enghouse Systems (TSX: ENGH) on 2020-12-30; the product line is now developed and maintained by Enghouse Interactive, and the brand continues to operate regionally (e.g. Altitude Software APAC). The company does not publish a modern public REST API, developer portal, or OpenAPI specification; integration is delivered through the proprietary uAgent SDK and packaged CRM/ERP connectors.

Altitude Software is profiled on the APIs.io network. Tagged areas include Company, Contact Center, Customer Interaction Management, Call Center Software, and Customer Experience.

Altitude Software’s developer surface includes support, engineering blog, and 2 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/altitude-software: open an issue to ask a question, or submit a pull request to add artifacts.

x-enrichment-note: Enriched 2026-07-17. No public API program found. Canonical domain altitude.com is now a parked domain
  for sale and no longer controlled by the company; the live first-party surface is the APAC regional site (altitudeapac.com,
  Enghouse Interactive). No OpenAPI/AsyncAPI/GraphQL spec, no developer portal, no /.well-known (404), no llms.txt (404),
  no public package registries — integration is via the proprietary on-prem uAgent SDK only. Identity hygiene applied; no
  artifacts fabricated.
