API Authentication and Permissions

5 vues Markdown

How a key is issued, how it travels on a request, and how its permissions decide what it may reach.

Overview

Every credentialed call carries an API key and nothing else. There are no sessions and no cookies, so a call behaves the same from a server, a laptop or a browser tab.

A key holds three things: the surface it belongs to, the list of permissions it was granted, and a request budget per minute. Those three are checked in that order on every request, and the first one that says no ends the call.

The key itself is never stored. What the installation keeps is a hash of it plus the first few characters for display, so a lost key cannot be recovered from the panel. It can only be replaced.

Prerequisites

Panel access to issue an admin key, or a customer account to issue a client key.
A place to store the key that is not your source tree.

Walkthrough

Issue a Key

For the admin surface, open Settings → API Credentials in the panel and create a credential.
For the client surface, the customer creates their own under API Credentials in their account, at /api-credentials.
Copy the key from the confirmation. It is shown once and never again.

Grant Permissions

Tick the actions the key needs. Each checkbox is one Group/Action pair, which is the same name the endpoint documents.
Grant the narrowest set that does the job. A key that only reads invoices cannot be turned against your clients.
Optionally raise or lower the per-minute budget for that one key; empty means the installation default.

Send It and Verify

Put the key in an Authorization: Bearer header, or in X-Api-Key if your client cannot set the first one.
Call whoami on the surface you issued for. It answers with the key's identity, its permissions and, on the client surface, the account behind it.
A 403 here means the key is real but belongs to the other surface. Check the address, not the key.

Reference

wak_ + 32 characters Reaches /api/v1/admin. Issued by staff, scoped by permission, not tied to any one customer.

wck_ + 32 characters Reaches /api/v1/client. Bound to the account that created it; every query it makes is filtered by that account.

Clients/GetClients One action. The safe default and the one the documentation names on every endpoint.

Clients/* Every action in that group, including ones added by a later version. Convenient, and wider than it looks.

* The whole surface. Reserve it for a key you fully control and can rotate quickly.

The refusals are distinct on purpose, so a failing integration tells you which of the three checks stopped it.

401 missing_token No key arrived. Usually a header the client dropped, not a permission problem.

403 audience_mismatch A real key on the wrong surface.

403 insufficient_scope The key is valid and the endpoint exists, but that action was not granted. The message names the missing permission.

429 rate_limited The per-minute budget is spent. Retry-After says how long to wait.

Example

authenticated call

KEY=$(cat ~/.config/wisecp.key)

curl -H "Authorization: Bearer $KEY" \
     'https://panel.example.com/api/v1/admin/whoami'
# {"data":{"id":7,"type":"admin","name":"Billing sync","permissions":["Invoices/*","Clients/GetClients"]}}

PHP

$ch = curl_init('https://panel.example.com/api/v1/admin/whoami');
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER     => ['Authorization: Bearer ' . getenv('WISECP_API_KEY')],
]);

$body = json_decode(curl_exec($ch), true);
curl_close($ch);

$permissions = $body['data']['permissions'] ?? [];

Pitfalls

The key is shown once

Only a hash is kept, so there is no screen that reveals it later and no support request that can retrieve it. If it is lost, regenerate the credential and update whatever was using it. Treat a regeneration as a small outage and plan it.

Ignoring a 429 costs more than obeying it

The budget is a fixed one-minute window: 120 requests for an admin key and 60 for a client key unless the installation says otherwise. A caller that keeps hammering far past its budget is locked out for a while rather than merely refused. Read X-RateLimit-Remaining and pause on Retry-After.

Repeated bad credentials park your address

Failed authentication is counted per address, and enough failures in a short window earn a temporary block with a too_many_auth_failures answer. A retry loop around a wrong key will find this before you do, so fail loudly on 401 instead of retrying.
