Integrations & API

Easily connect Stallingo to everything you already use

Your website, your accounting, your barrier or your own Excel reporting: with the Stallingo API you read and write data securely, with exactly the permissions you decide. You create an API key yourself — no ticket, no waiting.

curl https://stallingo.nl/api/mij -H "Authorization: Bearer sk_live_…"
# → { "data": { "stalling": "Stalling Flevoland", "via": "api-key", "scopes": ["klanten:lezen", …] } }

Create a key yourself

As owner you create a key in Settings → API integrations within a minute. No request, no waiting.

Scoped: only what is needed

Per key you choose exactly which permissions apply: e.g. read customers only, or create appointments only. Revoke at any time with one click.

Plain REST + JSON

The same API our own app uses. Works with any language and with tools like Zapier, Make, n8n or Power Automate.

What can you do with it?

Integrations storage businesses use every day

Registration form on your own website

New customers sign up on your site and appear on the waiting list in Stallingo right away — including object type and length.

Accounting kept up to date

Fetch sent and paid invoices and push them to Exact, Moneybird, Xero or QuickBooks.

Access and barrier

Check at the gate whether a licence plate belongs to a customer with a scheduled pick-up.

Your own dashboards

Occupancy per shed, revenue and outstanding items in Power BI, Google Sheets or your own reporting.

Appointments from your planning

Schedule pick-ups and drop-offs from an external planning board; the customer automatically receives an e-mail confirmation.

Multiple locations

Consolidate data from all your locations into one overview, with a separate key per location.

How it works

Connected in three steps

1
Create an API key
Go to Settings → API integrations, name the key and tick the scopes the integration needs.
2
Send the key as a Bearer token
Every request gets a header Authorization: Bearer sk_live_… . Test it right away with GET /api/mij.
3
Read and write via JSON
Use the endpoints below. Whatever you do via the API shows up in the app immediately — and vice versa.

Documentation

API reference

All endpoints speak JSON and live under the base URL below. Responses look like { data: … }; errors like { error, message, details }. Field names are in Dutch (the product language).

Base URLhttps://stallingo.nl/api

Authentication

Send your API key in the Authorization header as a Bearer token. Keys start with sk_live_ and belong to one storage business. Keep them secret (never in frontend code or a repository). A revoked or expired key returns 401.

Authorization: Bearer sk_live_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Scopes

Each key has a set of scopes. A request to an endpoint the key has no scope for returns 403 with the missing scope in the message. User and settings management is deliberately never available via the API.

Example: create a customer and schedule an appointment

First create the customer, then attach an object and schedule a drop-off. The customer automatically receives an e-mail confirmation on behalf of your business.
