I will integrate any API, payment gateway, or third party service


About this gig
Hi,I'm Aldi.I have 3-5 years of experience building custom web systems and integrations, and I am now bringing that experience to Fiverr.
If your app needs to connect with a payment gateway, CRM, AI service, database or any third-party platform, I can build the connection and make sure data moves reliably between both systems.
I can help with:
- REST API integrations
- Stripe and payment gateways
- OpenAI and third-party services
- Authentication and webhooks
- Database and Supabase connections
- Debugging an existing integration
My process:
1. I review the API documentation and your current system.
2. We confirm the exact data flow and expected result.
3. I build and test the integration.
4. You receive the source code and a clear handover.
Please message me before ordering. API projects vary significantly, and I want to confirm the correct package, delivery time and scope first.

FAQ
Do I need to contact you before ordering?
Yes. Send me the API documentation, your current stack and the result you need. I will confirm scope, price and delivery time.
Which APIs can you integrate?
I can work with documented REST APIs, payment gateways, OpenAI, Supabase, CRMs and other third-party services. Message me with the documentation first.
Can you fix an existing API integration?
Yes. Send the current error, relevant code and API documentation. I will review whether it fits the Basic package or needs a custom quote.
Will I receive the source code?
Yes. Source code is included in all three packages.
Can you integrate Stripe or another payment gateway?
Yes. I can connect payment flows, webhooks and database updates. Exact scope depends on the checkout and subscription requirements.
Do you provide API keys?
No. You must provide your own authorized API credentials. Never send secrets in the initial message; share them securely after the order begins.
