Crypto payment API for B2B integrations

A crypto payment API for B2B programs is a server-to-server contract: create payments, observe lifecycle transitions, verify webhooks on raw bytes, and reconcile against finance controls. Kobbopay is designed for that integration style—not browser-embedded secrets or checkout-only widgets without operational depth.

01

Operational overview

Payment APIs in crypto infrastructure expose creation, status reads, and event notifications. The operational burden sits in how your team maps those signals to orders, refunds, and ledger postings—not in the HTTP verb alone.

Kobbopay emphasizes explicit lifecycle semantics so engineering, finance, and support share one vocabulary. Collapsing detection and finality silently creates audit risk when confirmation policy matters.

Public marketing copy on this site is conservative. Environment-specific OpenAPI anchors and signing details are shared after merchant approval and integration alignment.

02

Integration concepts

Place API keys only on your servers. Never embed keys in mobile apps, front-end bundles, or public repositories.

Create payments with stable merchant references your reconciliation jobs can join to invoices or subscription IDs.

Consume webhooks with verification middleware separated from business logic. Parse JSON only after signature validation succeeds.

Design handlers for at-least-once delivery: use idempotency on payment_id (or your documented stable key) before irreversible side effects.

See the merchant integration architecture guide for system boundaries and the developers page for illustrative request sketches.

03

Rails and configuration scope

API requests specify assets and networks your environment supports. Unsupported combinations should fail at creation with clear errors—not after funds arrive on an unconfigured corridor.

Non-production and production are separate configurations: credentials, webhook endpoints, rails, and confirmation policy may differ.

Rail selection is a joint decision between engineering and treasury. Use the rail selection reference matrix when comparing operational cost—not marketing coverage lists.

04

Reconciliation and trust positioning

API events are inputs to reconciliation—they are not a substitute for finance controls. Maintain exception queues for amount mismatches, wrong assets, and delayed confirmations.

Asynchronous settlement means your jobs must tolerate timing skew between commerce state, provider state, and books finality.

Kobbopay publishes playbooks and references so integration architects can cite models during design reviews without inventing ad hoc definitions per project.

05

Webhooks and security

Treat webhook endpoints as authentication boundaries. Rate-limit, monitor signature failures, and alert on replay windows that exceed policy.

Document which events your deployment emits and how each maps to internal states—finance should sign off before production traffic.

For depth, read verify crypto webhooks safely (journal), webhook replay handling (guide), and webhook delivery expectations (reference).

  • Retries are normal. Webhook delivery is at-least-once. Design consumers to tolerate duplicates and out-of-order arrivals where possible.
  • Asynchronous by design. Payers, chains, and your servers operate on different clocks. UI and finance should not assume synchronous finality.
  • Eventual consistency. API reads, webhooks, and portal views may briefly diverge during transitions. Reconciliation jobs exist to converge truth.

Walkthroughs: /operations

  • Reviewed merchant onboarding
  • Server-side API keys only
  • Signed webhook verification on raw bytes
  • Explicit lifecycle states
  • Operational reconciliation model
  • No client-side secrets

If this model matches your B2B program, align engineering and treasury on lifecycle semantics, complete reviewed merchant onboarding preparation, run webhook verification tests in the first environment you receive, then submit a structured access request with required rails and use case context.

Frequently asked questions

Is there a public sandbox API key on this site?
No. Non-production access is discussed after approval and scope alignment. Plan for server-to-server patterns and verification tests in the first environment you receive.
Does the API replace reconciliation tooling?
No. It feeds operational data. Your finance stack still owns matching, exception resolution, and treasury recognition policy.
What should we document before production?
Lifecycle mapping, webhook verification steps, idempotency strategy, monitoring baselines, and escalation paths for settlement drift—see playbooks for procedural templates.
Can we integrate from a browser-only app?
B2B integrations should be server-mediated. Browser-held secrets increase exposure and complicate security review.
