Map the contract
Document credentials, environments, request shapes, callbacks, error semantics, rate limits and business ownership.
Integration lifecycle
Integrate providers
without leaking complexity.
A provider connection is more than an API call. Treat contract discovery, adapter design, verification, retries, reconciliation and provider upgrades as one lifecycle.
Isolate provider logic
Translate provider-specific payloads into stable application concepts at a dedicated boundary.
Authenticate events
Validate signatures or configured secrets, reject malformed events and make callback processing idempotent.
Design for transient failure
Use bounded retries and dead-letter/reconciliation paths instead of retry storms.
Compare business state
Payments, shipments and provider-side actions may succeed even when local acknowledgements fail. Reconciliation closes that gap.
Version the adapter
Test provider API changes at the adapter boundary and preserve the internal contract wherever practical.
Provider-specific instructions remain authoritative.
The public Thonem site describes a safe integration pattern. Exact endpoints, signatures, credentials and API versions must come from the provider and the deployed project.
