iOS & Android API, Login and SDK Integration

We implement native API/SDK integrations around authenticated sessions, retry semantics, resource authorization and offline recovery. We test the failure boundary, not just the happy-path response.

Integration architecture

The app works with test data but fails when real accounts, devices and networks are involved.

Connect mobile clients to the right backend, identity and device capabilities without fragile integration logic. We work against agreed platforms, repository access, constraints, milestones and acceptance tests—not a one-size-fits-all app package.

REST/JSON and GraphQL client integration, contract tests, pagination, retries and idempotency.

Integration path

Integration and verification

Engineering capabilities

  • REST/JSON and GraphQL client integration, contract tests, pagination, retries and idempotency.
  • OAuth/OIDC, passkeys, Credential Manager, Sign in with Apple and secure session lifecycle where appropriate.
  • Keychain/Keystore storage design, App Attest/Play Integrity integration and backend verification paths.
  • Push notifications, deep/universal/app links, background sync and account recovery.
  • Maps, location permissions, camera, QR/barcode, media, file exchange and secure sharing.
  • NFC, BLE, device connectivity and related platform permission/transport failure handling.
  • Payments, identity vendors, CRM/support platforms and analytics SDKs against approved data-flow rules.
  • Integration tests for timeouts, denial, duplicate callbacks, stale tokens, network loss and server errors.

Integration and delivery

  • Integration map, trust boundaries, permissions and environment configuration.
  • Client and optionally backend implementation with typed contracts.
  • Staging mocks, negative-path tests and telemetry for failed integrations.
  • Secrets/permissions review, runbook and handoff instructions.

Frequently Asked Questions

Answers to your questions

Can the mobile app enforce account permissions?

The client can guide UI behavior, but every protected backend action still needs server-side identity, object and tenant authorization.

Can we integrate SDKs without exposing private credentials?

That is part of the design. Provider secrets stay in authorized server systems, not embedded in a mobile binary.

Our Approach

How we work with your team

Discovery

We review your goals, existing environment and the systems or workflows involved.

Engagement planning

Code changes, integrations, production access and release support are agreed separately where needed. We define the delivery plan and responsibilities together.

Results and handoff

Your team receives the agreed implementation or findings, testing results and a clear next-step plan.
