Integrations and API development
Determinds delivers integrations and API development that connect the platforms you already use, covering payments, Salesforce, AI services, and shipping, with retries, reconciliation, and failure handling designed in from the start.
01 What we connect
Separate platforms, connected as one system
Determinds designs, builds, and maintains integrations for businesses whose CRM, warehouse, payments, and analytics sit on separate platforms, from a single webhook between two SaaS tools to a middleware layer across dozens of systems.
Payment gateways
Payment integrations that run inside PCI DSS environments across Stripe, PayPal, Adyen, Checkout.com, and regional gateways such as Paymob, Fawry, MPGS, and Cybersource, covering multi-currency, subscriptions, refunds, and webhook reconciliation into finance.
Shipping and logistics
Real-time connections to DHL, FedEx, UPS, Aramex, and third-party logistics providers, automating labels, tracking events, stock levels, and returns so your warehouse works on live data.
Salesforce and CRM
Two-way integrations between Salesforce and your ERP, marketing, support, and billing platforms through the Salesforce REST and Bulk APIs, keeping deal status and revenue current everywhere.
Marketing automation
Mailchimp, Klaviyo, HubSpot, and ActiveCampaign triggered by real backend events, with consent, deduplication, and unsubscribe synchronization handled in the integration layer.
Advertising platforms
Server-side conversion events sent to Google Ads, Google Analytics 4, and Meta through the Measurement Protocol and the Conversions API, which stay reliable when ad blockers and cookie consent are in place.
AI and language models
OpenAI, Claude, and open-source models integrated into support queues, knowledge bases, and document pipelines, with context management, rate limits, fallback routing, and cost controls.
AI systemsAnalytics and data pipelines
ETL and reverse-ETL into Snowflake, BigQuery, or Redshift, with dashboards in Metabase, Looker, or Power BI tailored to each team.
02 Architecture
Observable, documented, and maintainable integrations
Determinds designs integrations on OpenAPI standards, event-driven architecture, message queues, and API gateways, so every connection is observable and maintainable from the day it ships and stays dependable as your systems grow.
Where no connector exists, or none meets your performance and security requirements, our team builds the API itself, documented in OpenAPI, secured with OAuth 2.0 and API keys, rate-limited, versioned, and tested end to end before it serves a production request.
03 How we deliver
From system map to a monitored integration
Discovery and system mapping
We audit every system involved for authentication, rate limits, data schemas, webhook support, and existing failure modes.
Integration blueprint
A written blueprint covers data flows, error handling, retry logic, and monitoring hooks, and you approve it before the build begins.
Development and unit testing
Code is tested against sandbox and production environments, including rate-limit exhaustion, partial failures, and malformed payloads.
End-to-end testing
Full scenarios run at production data volumes, and your acceptance testing follows a structured plan.
Deployment and monitoring
Alerting on failure rates, latency, and sync lag is live from deployment, giving our maintenance team full visibility from the first day.
Documentation and handover
Technical documentation, runbooks for common failures, and a handover session with your team.

04 Frequently asked
Questions about integrations
What is the difference between an API integration and a custom API?
An API integration connects two existing systems through their published APIs, such as syncing Salesforce with a billing platform, while a custom API is a new interface Determinds builds so your own system can serve other applications, a mobile app, or outside developers. Many projects need both.
How long does an integration take?
Determinds sets each timeline by the systems and data transformations involved, which range from a single documented SaaS-to-SaaS connection to a phased enterprise rollout across legacy APIs. Every engagement starts with a written specification and timeline, and requirements reach scope sign-off in 5 working days.
Can a system with no public API be integrated?
In most cases, yes. Determinds can build a pipeline around database access, file exports, or webhook support, and for older systems the options include database-level integration, RPA-style automation, or a controlled migration, chosen on what the system can support.
How are credentials kept secure?
Determinds keeps secrets in environment-scoped managers such as AWS Secrets Manager or HashiCorp Vault, never in code or version control. Authentication uses OAuth 2.0 wherever the API supports it, with short-lived tokens and least-privilege scopes, and every credential and its rotation schedule is documented at handover.
What happens when a third-party API changes?
Determinds monitors every integration, so a failure is detected and addressed early, and planned deprecations are tracked through each provider’s changelog and migrated ahead of the deadline. Under a maintenance retainer, minor third-party version changes are handled within the SLA.
Are regional payment and logistics APIs covered?
Yes. Determinds integrates regional payment gateways including Paymob, Fawry, MPGS, and Cybersource alongside Stripe, and works with the global platforms operating in Gulf markets under their compliance requirements.
Can Determinds take over integrations another team built?
Yes. Determinds starts with a technical audit of what was built and what is missing, and stabilizes the high-risk components before ongoing support begins. Any immediate risk is raised in the audit report before an SLA is signed.
