Holded API
Holded ships a public REST API with 293 v1 endpoints spanning sales, inventory, accounting, CRM, and treasury; keys are self-serve on any paid plan. Quirks bite: a custom 'key' auth header, only the first key can write, no v1 webhooks, and rate limits surface as undocumented 429s.
Frequently asked questions
Holded scores D+ on the API Report Card. Holded ships a public REST API with 293 v1 endpoints spanning sales, inventory, accounting, CRM, and treasury; keys are self-serve on any paid plan. Quirks bite: a custom 'key' auth header, only the first key can write, no v1 webhooks, and rate limits surface as undocumented 429s.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Holded is a Barcelona-headquartered cloud-based all-in-one ERP and business management platform founded in 2016 and acquired by the Norwegian Visma Group in June 2021 for approximately EUR 120 million.
Vertical: Accounting/Tax/Audit (with strong overlap into Enterprise/HR/ERP) - Holded is the dominant cloud ERP/accounting/invoicing platform for Spanish freelancers (autonomos), small businesses, startups, and accounting firms (asesorias). Spanish freelancers and SMB owners use Holded as the daily operational tool for issuing invoices (factura, ticket, presupuesto), recording expenses by scanning receipts with the mobile app, reconciling bank transactions via PSD2 bank-feed connections to BBVA / Santander / Sabadell / Caixabank and 200+ other banks, generating quarterly VAT returns (Modelo 303), annual income-tax filings (Modelo 130 / 100 / 200), and statutory reports (Modelo 347, Modelo 349, Modelo 390).
Within the Spanish SMB and autonomo accounting/ERP segment Holded is one of the top three names alongside Quipu and Odoo (and ahead of Spanish incumbents like Sage 50, Contasimple, Anfix, A3 Software, and Cuentica for the cloud-native SMB tier).
Yes - for a Spanish SMB or autonomo Holded customer the platform is the central financial and operational dataset the company runs on, and is the regulatory system of record vis-a-vis the Spanish Tax Agency (AEAT) and Social Security (TGSS).
Founded in 2016 in Barcelona by Bernat Rius (CEO) and Javier Fondevila as one of the first cloud-native Spanish ERP startups, raising backing from Nauta Capital, Lanai Partners, and angel investors before being acquired by the Norwegian Visma Group in June 2021 for approximately EUR 120 million ($143M USD).
No native first-party webhook system in v1 - the production API surface still in use today has no event subscription model, forcing integrators to poll for changes; webhooks remain 'coming soon' in v2 with no firm GA date for production-grade event delivery. Only the FIRST API key generated on an account has read+write capability; all subsequent API keys are read-only, an unusual restriction that forces account owners to share the single bidirectional key across integrations or revoke/regenerate it (with cascading breakage) when an integration must be rotated.

Common alternatives include Quipu (by Sage), Sage 50 / Sage 200, A3 Software (Wolters Kluwer), Contasimple (Cegid), Anfix, Odoo. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
