Holded API

What Holded API is

Holded API lets businesses work with invoices, contacts, products, and other business data through software integrations. It is a REST/JSON API with Bearer authentication and cursor pagination, and its documentation lists 356 endpoints. The reference spans accounting, treasury, sales, inventory, contacts, CRM, projects, team and HR, calendar, inbox, and webhooks. API keys can use scoped permissions and must be sent over HTTPS. Webhooks deliver signed HTTP POST notifications for events such as invoice creation and payment receipt, with retries after unsuccessful delivery.

Monthly API quotas range from 500 calls on Plus to 100,000 or more on Premium, where overage is billed automatically. Holded lists integrations including Shopify, WooCommerce, PrestaShop, Stripe, PayPal, Google Drive, Zapier, and Make. The broader cloud business platform combines invoicing, accounting, CRM, projects, HR, inventory, and banking. Plans start at €15.00 per month on Plus, billed monthly, with prices excluding VAT; a 14-day trial is available. Plus includes 250 invoices per year, one connected bank, and one user. Holded is based in Barcelona, Spain, and was founded in 2016. The API is listed for Android, iOS, web, and API platforms.

Who it suits

Holded API suits businesses that need to manage Holded records programmatically across areas such as sales, accounting, inventory, and CRM. Its documented endpoints, scoped API keys, and webhooks also suit teams building integrations that need event notifications and controlled access.
