99.99% reads against a different threshold than a
standard customer signed at 99.9%).
Prerequisites
- A Pro plan or higher.
- The audience already authenticates against an Identity Provider capable of signing RS256 JWTs.
- A list of customers in the console. Open Customers, then
New customer, and set each customer’s External ID (the
value your tokens carry in
sub).
Configure the page

Switch the page to customer-scoped mode
Open the page in the console, then Access. Set:
- Mode: Customer-scoped (JWT + grant).
- Public key (PEM) or Or JWKS URI: same as JWT mode.
sub claim and matches it to a
customer’s External ID.2
Grant customers access to the page
Open Customers, select the customer, and add the page under
Page access grants. Repeat for each customer who is allowed to
view the page. Customers without a grant receive a 403 even with a
valid token.

Apply per-customer SLO targets (optional)
Open a customer, then SLO target overrides. Add an override with:
- The SLO whose target should be customer-specific.
- The customer’s contracted target percentage.
Same backend, different verdictsCustomer scopes apply at render time. A single underlying metric
can therefore back a
99% agreement with one customer and a
99.99% agreement with another, without duplicating the metric
definition or the agent’s collection work.Issuing tokens
Issue tokens for each customer with the agreed claim set.claims
sub must equal the customer’s External ID; tokens older than one
hour (by iat) are rejected.
Behaviour
- A customer without a grant for the page gets 403 even with a valid token.
- An expired token returns 401; issue a fresh token.
- SLO overrides are read on every render and require no caching on the consumer side.
