I will integrate any API into your app, CRM or website


About this gig
Two systems that do not talk to each other cost you a person's whole afternoon, every week, forever.
I connect them properly: authentication that does not expire quietly, retries when the other side goes down, and logs that tell you what happened instead of a blank screen.
ALREADY INTEGRATED
Stripe, Authorize.Net, MX Merchant, GoHighLevel, HubSpot, Twilio, ElevenLabs, AWS Cognito, Microsoft and Google SSO, Anthropic, OpenAI, QuickBooks, Airtable, Google Workspace, plus a long list of healthcare and pharmacy APIs.
WHAT YOU GET
A working connection, the source code, and a short walkthrough of how it behaves when something fails. Field mapping you can change yourself.
IF THE DOCS ARE BAD
I have done that before. Undocumented endpoints, odd auth schemes, XML in 2026. Send me what you have.
BEFORE YOU ORDER
Send the API docs and what you want it to do. I will quote you a real number, usually the same day, and tell you if a cheaper package covers it.

FAQ
What if the API I need is not on your list?
The list is just what I have already done. If it has a REST or GraphQL API, I can wire it up. Send me the docs and I will confirm before you order rather than guess.
