How long does a typical API integration take?

Most integrations take between 1 - 3 weeks from kickoff to launch. Simple two-tool connections can be done in a few days, while complex multi-platform workflows may take 3 - 4 weeks.

How much does API integration cost?

Simple integrations typically start around €500, while complex multi-platform workflows range from €1,500 - €5,000+. A fixed-price quote is provided after the free discovery call.

What if the tool I use doesn't have a public API?

Many tools offer APIs that aren't prominently documented. Alternatives like webhooks or custom solutions can also be used. Feasibility is evaluated during the discovery call.

Will the integration break if the API changes?

Integrations are built with error handling and monitoring. If an API changes, you're alerted immediately. Maintenance plans are available to keep integrations updated.

Do I need to give you access to my accounts?

Only API keys or OAuth access for the specific tools being integrated are needed. Personal login credentials are never required, and access can be revoked after the project.

What happens after the integration is live?

Documentation is provided explaining how the integration works. Ongoing maintenance plans starting at €80/month include monitoring, updates, and priority support.

I'm not technical - can you still help me?

Yes. Most clients are business owners, not developers. You just need to describe what manual work you want eliminated, and the technical side is handled entirely.

Custom API Integration Services. Connect Your Tools, Automate Your Business

Your business runs on dozens of tools: CRM, payment processors, project management, email marketing, and spreadsheets. But they don’t talk to each other. Every time you manually copy data from one platform to another, you’re burning time and risking errors.

I build custom API integrations that connect your tools and make data flow automatically – so you can stop being the middleman between your own software.

What Is API Integration (And Why Your Business Needs It)

API integration is the process of connecting two or more software applications so they can exchange data automatically. Instead of manually exporting a CSV from one tool and importing it into another, an API integration handles that transfer in real time – instantly, accurately, and without human involvement.

If you’ve ever wished your website form submissions would automatically appear in your CRM, or that a new Stripe payment would trigger an invoice in your accounting software, that’s exactly what API integration solves.

Businesses that invest in custom API integrations typically see:

5–20 hours saved per week on manual data entry and repetitive tasks
Fewer errors from copy-paste mistakes and outdated spreadsheets
Faster response times to leads, orders, and customer requests
A unified view of their data across all platforms

API Integration Services I Offer

Third-Party API Connections

I connect your website or web application to the APIs of the tools you already use – payment gateways, CRMs, marketing platforms, project management tools, and more. Whether it’s a straightforward two-tool sync or a complex multi-platform data flow, I handle the implementation from start to finish.

Custom Workflow Automation

Beyond simple connections, I design workflows where one event triggers a chain of automated actions across multiple platforms. A new form submission can create a CRM contact, notify your team on Slack, send a personalized email, and log everything in a spreadsheet – all without you lifting a finger.

Data Synchronization

I set up real-time or scheduled data syncs between your tools so that your records stay consistent everywhere. No more conflicting information between your CRM and your email marketing platform, or outdated inventory counts on your website.

API Troubleshooting & Optimization

Already have integrations that aren’t working properly? I audit existing API connections, fix broken data flows, optimize performance, and ensure your integrations are reliable and maintainable long-term.

How It Works — My Process

1. Discovery Call (Free, 30 minutes) We discuss your current tools, pain points, and what you want automated. I’ll ask about your data flow, team size, and business goals to understand the full picture.

2. Scoping & Proposal I map out the integration architecture – which tools connect to which, what data flows where, and what triggers what. You receive a clear proposal with scope, timeline, and pricing.

3. Build & Test I develop the integration in a staging environment, testing every data flow and edge case. I handle authentication, error handling, rate limits, and data validation so nothing breaks in production.

4. Launch & Handoff Once tested, the integration goes live. I provide documentation on how the integration works, what to monitor, and how to request changes. I also offer ongoing maintenance if needed.

5. Ongoing Support (Optional) Integrations sometimes need updates when APIs change, or your business evolves. I offer maintenance plans to keep everything running smoothly.

Case Studies — Real Integrations I’ve Built

Buzzsprout → WordPress (Podcast Auto-Publish)

Problem: A podcaster was manually uploading each new episode to their WordPress site after publishing on Buzzsprout.

Solution: I built a custom integration using the Buzzsprout API that automatically pulls new episodes and publishes them on the website – with episode art, descriptions, and player embeds.

Result: Zero manual work per episode. New episodes appear on the website within minutes of publishing. → See it live on Martina’s website

AP News API → WordPress (Real-Time News Feed)

Problem: A client wanted to display real-time news content from AP News on their website without manually curating articles.

Solution: I integrated the AP News API into their WordPress site with category filtering and automatic updates.

Result: Fresh, relevant news content on the site 24/7 without any editorial effort.

Website Forms → Notion (Automated Lead Management)

Problem: A business was receiving form submissions via email and manually copying each one into Notion for tracking.

Solution: I connected the website contact forms directly to Notion’s API, creating a new database entry for every submission with all form fields mapped automatically.

Result: Every lead is captured instantly in Notion, organized, and ready for follow-up – no data entry required.

Why Work With Me Instead of a Large Agency?

	Me (Danit Web Agency)	Typical Large Agency
Communication	You talk directly to the developer who builds your integration	Account managers relay messages; delays are common
Experience	15+ years of web development; deep expertise in WordPress, Laravel, React	Rotating junior developers who may not know your stack
Speed	Most integrations delivered in 1–3 weeks	Weeks of scoping meetings before work even starts
Cost	No overhead from large teams; you pay for development, not management layers	High hourly rates padded with project management fees
Flexibility	I adapt to your needs mid-project without a change order process	Rigid scope; every change costs extra

FAQ

Pricing depends on the complexity of the integration — how many tools are involved, how the data needs to be transformed, and whether custom logic is required. Simple integrations typically start around €500, while complex multi-platform workflows range from €1,500 – €5,000+. I provide a fixed-price quote after the discovery call so there are no surprises.
