API Development

Seamlessly connect systems, automate workflows, and unlock the power of your data with custom API development and strategic third-party integrations.

Hi, I'm Robin. I build scalable, secure APIs to connect systems like Salesforce, streamline processes, and unlock data potential. Effective API development is crucial for modern business innovation and efficiency.

If you'd like to hire me, Let's connect and figure out the details!

In today's interconnected digital landscape, APIs (Application Programming Interfaces) are the backbone of modern software. They enable different systems and applications to communicate, share data, and automate processes. Effective API development and integration are crucial for businesses looking to innovate, improve efficiency, and create seamless user experiences.

I have extensive experience in designing, building, and integrating APIs, from simple RESTful services to more complex microservice architectures. My focus is always on creating APIs that are secure, well-documented, scalable, and easy for other developers to consume.

Connecting Your Digital Ecosystem

Modern businesses rely on a multitude of software solutions – CRMs, marketing automation platforms, payment gateways, internal tools, and more. APIs act as the glue that binds these disparate systems together, allowing for automated data exchange and streamlined workflows.

Whether it's syncing customer data from Salesforce to WordPress, processing payments via Stripe, or connecting your application to a third-party data source, robust API integrations can eliminate manual data entry, reduce errors, and unlock new capabilities.

Building Custom APIs for Your Needs

Sometimes, off-the-shelf integrations aren't enough. Your business might require a custom API to expose specific data or functionality to internal tools, mobile apps, or trusted partners. I can help design and build RESTful APIs that are secure, well-documented (e.g., using OpenAPI/Swagger), and adhere to best practices for versioning and maintainability.

Security and Scalability

Security is paramount in API development. I implement industry-standard authentication and authorization mechanisms (like OAuth 2.0, API keys) and ensure data is protected in transit and at rest. Scalability is also a key consideration, designing APIs that can handle growing traffic and data volumes efficiently.

API Development & Integration FAQs

My bread‑and‑butter is JSON REST integrations. This includes connecting with CRMs, social feeds, and bespoke client APIs, even those with inconsistent HTTP codes. I've integrated systems like Iterable for newsletter signups and user preferences, Piano for paywalls, Classy for donations, Salesforce for event data, and Greenhouse for job listings.

Yes, I have deep experience with JSON REST integrations. I also have experience with GraphQL and SOAP APIs – yeah, SOAP was a nightmare! but I can handle it.

A challenging project was for the Kurt Weill Foundation, integrating their WordPress site with Salesforce. This required real-time synchronisation of a large number of records (events, dates, performers) across multiple custom fields and data types, with the ability to manually override any field within WordPress. Another was for Forward.com, integrating Piano for subscriptions and Iterable for email and event tracking, managing custom logic for user status changes and donations via Classy.

I focus on meticulous one‑for‑one data‑mapping. For instance, I successfully swapped out Insightly for Drip CRM for a client without losing a single field, ensuring all data was accurately transferred and functional in the new system.

I build robust error handling, logging, and retry mechanisms. For example, when working with Iterable, I managed graceful error-handling for issues like invalid email rejections. For the Greenhouse API, I handled rate limits and pagination. This is especially important with bespoke client APIs that might have inconsistent HTTP codes.

Whether you need to integrate existing tools, build a new API to power your next product, or modernize legacy systems, I can provide the expertise to create reliable and efficient solutions. Reach out to discuss your API development needs.
