I will integrate a third party API into your web application
Joao P.
About this gig
Need your web app to exchange data with an external service reliably? I will integrate one documented third-party API into a defined workflow with clear mapping, validation, failure handling, and handoff.
Packages may include authenticated requests, data retrieval or CRUD, webhooks, structured errors and logs, focused tests, and setup notes.
Technology and stack selection: For an existing app, I preserve its architecture when the relevant code uses my supported stack: Django/DRF, React, Next.js, or JavaScript. For a new integration layer, I can recommend a supported option based on authentication, data flow, hosting, maintenance, and security. I do not promise unsupported stacks.
I do not reverse-engineer private APIs, bypass restrictions, obtain approvals, or include provider fees. OAuth, payments, webhooks, file transfers, heavy rate limits, or poor documentation require review.
Send the official docs, desired data flow, current stack, and success criteria so I can confirm fit and package.

FAQ
Which technology will you use?
For an existing application, I normally preserve its architecture when the relevant work is within my supported stack. For a new integration layer, I recommend the simplest supported option that fits authentication, security, maintenance, hosting, and data-flow requirements.
Can I choose the technology?
Yes, when it is technically appropriate and within the technologies I support professionally: Django/DRF for backend work and React, Next.js, or JavaScript for applicable frontend work. I do not offer services in Node, Laravel, FastAPI, Flask, Vue, or Angular delivery.
What if I do not know which technology I need?
Describe the existing system, provider, desired workflow, hosting, and maintenance needs. I will recommend an appropriate supported approach or tell you clearly if the project is not a fit.
Which APIs can you integrate?
Documented REST/JSON APIs with legitimate developer access, clear authentication, and preferably sandbox or test credentials. I must review the official documentation before confirming scope.
Are OAuth2, webhooks, or payments included?
Only when explicitly listed in the package or custom offer. OAuth scopes and refresh flows, webhook verification, idempotency, and payment-state handling add material complexity.
Are provider fees or approvals included?
No. The buyer owns the provider account and pays subscriptions, usage, hosting, and approval costs. I do not bypass restrictions or guarantee provider approval.
What counts as a revision?
A revision corrects the agreed integration against the approved data flow and acceptance criteria. A new endpoint, provider, workflow, or changed API requirement is new scope.
