Build on Qashio

The v1 ERP connector exposes the reference and spend data Qashio holds in sync with your accounting system. It stays available for existing integrations; new work should target API 2.0.

This is the legacy connector. New integrations should build against API 2.0, which adds card issuance, user invitations, refund mapping and OAuth token issuance. The changelog maps every path.

Your first request

Every request carries a Bearer access token, which you get by runningQashio's OAuth login flow: your user signs in with their Qashio account, approves access, and your server exchanges the resulting code for a token. The token is already bound to that company, so you never send acompanyId or an x-api-key header.

Shell

curl -X GET 'https://erp.qashio.com/company/summary' \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer <access_token>'

Base URL https://erp.qashio.com. The API reference lists every environment.
