API Development Services for Integrations and Backend Systems

Security scope follows what the API exposes, customer data, payments, partner access or internal-only services, not a checkbox template applied to every project. We define auth model in discovery: API keys with scopes, OAuth flows, JWT with short-lived tokens, mutual TLS for high-trust partners or IP allowlists where appropriate. Input validation, HTTPS everywhere, secure secret storage and least-privilege vendor credentials are baseline. Webhook endpoints verify signatures and reject replayed payloads. We do not claim SOC 2 or penetration-test outcomes unless you commission them separately. Rate limiting and abuse detection enter scope when endpoints are public or partner-facing. Staging uses separate keys and sandboxes so production credentials never appear in dev channels. Managed Hosting & Care covers patching, SSL renewal and infrastructure hardening after launch. Share compliance constraints, PCI proximity, GDPR data residency, healthcare rules, in the roadmap form so security architecture is priced honestly from the start.

Yes. documentation is a deliverable, not an afterthought once endpoints are already in production. We produce OpenAPI specifications or equivalent reference docs with auth instructions, example requests and responses, error codes and versioning notes so internal teams and partners integrate without Slack archaeology. Changelog discipline matters when fields or behaviours change: deprecated paths, sunset dates and migration guides reduce surprise breakages for mobile apps and third-party consumers. Postman collections or similar tooling can accompany larger partner APIs when scoped. Documentation lives in a repo or portal your team controls, not trapped in a contractor account. For microservices or middleware with several consumers, we map which team owns each contract. Custom Web App Development benefits when front-end and API docs stay aligned from discovery. If you inherit undocumented endpoints, refactor-and-document phases are scoped separately from net-new builds during discovery via contact.

Yes. CRM and form sync is core integration work, scoped around direction of sync, field mapping and what happens when records conflict. One-way flows, website form to CRM lead, differ from two-way account updates between product database and Salesforce. We map required fields, deduplication rules, owner assignment and retry behaviour before writing code. HubSpot, Salesforce, Pipedrive and custom CRMs via REST each bring rate limits, OAuth refresh and object quirks that affect timeline. ERP connections, NetSuite, SAP exports, warehouse systems, often need middleware when the vendor API is incomplete or batch-oriented. Staging sandboxes and test records are documented before build starts; production cutover includes a reconciliation checklist. Platform Migration applies when CRM or storefront replatforming must preserve historical sync logic. Complexity follows object count, sync direction and acceptance tests, not a flat per-field estimate. Describe current tools and pain points in the roadmap form so integration depth is visible early.

Rate limits and retries are designed into the architecture, not discovered in production when a nightly sync gets throttled or a payment webhook fires twice. We review vendor documentation for per-second, per-minute and daily caps, then choose queue workers, batching and backoff strategies that stay inside limits while completing work on schedule. Webhook handlers use idempotency keys so duplicate delivery does not double-charge or duplicate orders. Failed jobs land in retry queues with exponential backoff; persistent failures alert operators instead of vanishing silently. Synchronous HTTP endpoints avoid long transforms that block responses, heavy work moves to background workers. Monitoring hooks log latency, error rates and queue depth so ops sees pressure before customers do. Load testing against sandboxes validates assumptions when volume is high. Managed Hosting & Care can include alert routing and runbook updates after launch. Share expected transaction volume and peak patterns in discovery so rate-limit strategy matches reality.

Hosting follows uptime requirements, data residency, team skills and whether the API sits beside an existing app or stands alone as integration middleware. Node and Laravel APIs commonly deploy to cloud VPS, container platforms or PaaS environments with separate staging and production, credentials rotated and environments isolated. We document deployment pipeline, env var ownership and rollback steps before cutover so your team is not guessing during an incident. SSL, DNS, firewall rules and log aggregation enter scope when the API is customer- or partner-facing. Without a defined owner, APIs often miss dependency updates, leak keys in shared docs or break when upstream TLS requirements change. Managed Hosting & Care covers monitoring, backups, patching and incident response when you want brightcode as that owner. If your internal DevOps team hosts, we hand over infrastructure-as-code or runbooks and stay available for integration expansion. Discovery via contact surfaces hosting gaps when no one clearly owns production today.

Maintenance keeps endpoints compatible with evolving vendors, schemas and security requirements, not just keeping the server powered on. Typical care covers dependency updates, SSL and certificate renewal, monitoring alert tuning, webhook secret rotation, vendor API version upgrades and small contract adjustments when business rules change. When HubSpot deprecates a field or Stripe adds a new event type, someone must schedule the change, test in staging and deploy, maintenance scope defines who that is. Bug fixes for sync drift, failed jobs and auth expiry belong here; net-new product features usually scope as build phases. Documentation updates accompany behaviour changes so partners are not surprised. Retainer or ticket-based care is agreed before launch, not negotiated during a finance-discovered sync failure. Software & API Development retainers extend middleware when new systems join the stack. Custom Web App Development continues when the API feeds new app surfaces. Compare care options in the roadmap before committing to a build-only contract.

Timeline follows endpoint count, auth complexity, vendor sandbox access, data mapping depth and how quickly stakeholders approve contracts, not a template week count. A focused webhook processor with one vendor and clear event types can move quickly once the roadmap is approved. Multi-system CRM sync, ERP middleware or public partner APIs need longer for security review, idempotency testing and staging validation against sandboxes. We phase work so critical flows, payment capture, lead creation, order export, can launch first and secondary syncs follow rather than blocking go-live on every edge case. Third-party approval delays for OAuth apps or partner credentials often influence dates as much as development hours. Platform Migration adds cutover planning when APIs must switch without downtime. Share your brief via contact and we outline realistic phases with milestones. Rush timelines are possible when scope is frozen early, vendor docs are complete and decision-makers respond on schedule.

The roadmap reviews your URL, systems diagram or integration brief against data flows, auth requirements, vendor constraints, failure modes and launch risks for your stated goal. You receive prioritised integrations, suggested phasing, stack recommendation, documentation expectations and practical next steps, not a generic backend capabilities PDF. It is designed for teams comparing backend development agencies, operators planning CRM or payment sync and product leads deciding whether to build middleware vs buy another connector. Request it via the form on this page or contact with your URL and goal. There is no obligation to proceed; many teams use the output internally before approving budget. If your situation spans several ERPs, compliance regimes or undocumented legacy APIs, the contact flow is the right place to add context.
