Three levels of reading
Integrate in a few hours with the Quickstart, customise via Advanced, inspect the full OID4VP surface via Raw. Pick the depth that matches your need — each level links to the next.
Quickstart
« I want a flow that works in a few hours. »
Two business parameters (useCase + jurisdiction),
one snippet, one signed receipt. Tessaliq picks the variant, format
and wallet for you. Targets 95 % of integrations.
Advanced
« I want to customise the behaviour. »
Override credential formats, response modes, wallet whitelists.
Legacy policy parameter. Feature flags runtime.
Webhook vs frontend callback pattern. For teams with compliance
or audit constraints.
Raw / Spec-level
« I need the full OID4VP surface. »
Swagger, OIDF conformance plans, DCQL specifics, HAIP profile, ISO 18013-5 & 18013-7 semantics, trust stores, receipt JWT schema. For auditors, conformance test plans, interop partners.

Tessaliq does not offer a self-serve signup form today. Sandbox API keys are issued manually after a short conversation on your use case — this keeps onboarding clean while the product is in Alpha and ensures we understand the jurisdiction and compliance context before provisioning a key.
See our architectural decision ADR 0014 for the rationale and the conditions under which self-serve will be re-enabled (mid-2027 at the earliest).
