I will integrate a documented rest API into your node js app
Luis G
About this gig
Connect your Node.js app to the external service your business needs.
I'm Luis, a software engineer with 7+ years of experience. I work with Node.js, TypeScript and NestJS to integrate documented REST APIs.
Each package covers ONE external endpoint (one method + route), ONE agreed action and up to 10 JSON fields.
BASIC: Integration with API key or an existing token, HTTP error and timeout handling, manual verification, source code and setup notes.
STANDARD: Basic + input validation, field mapping, detailed code comments and 3 automated tests.
PREMIUM: Standard + one save operation in an existing PostgreSQL or MySQL table and a persistence test. Your database connection and schema must already work.
You'll need a working app, API documentation, test access and sample inputs with expected results.
One revision covers adjustments within the agreed scope.
Excluded: new OAuth flows, payments, webhooks, bulk processing, two-way sync, database migrations, UI changes, deployment and existing bugs. API fees are yours.
Message me before ordering with the API documentation and your exact goal so I can confirm compatibility and scope.

FAQ
What do you need before I place an order?
Please send the API documentation, your app’s framework and the exact action you need. Your Node.js app must already run. You’ll also need test access and sample inputs with expected results. Please don’t send production passwords or API keys in your initial message.
What does “one endpoint” include?
One endpoint means one HTTP method and route from one external API, used for one agreed action, such as creating a contact or retrieving an order. Each package covers up to 10 JSON fields. Additional endpoints, bulk processing and multi-step workflows require a separate quote.
Which package should I choose?
Basic includes the integration, error handling, manual verification, source code and setup notes. Standard adds input validation, field mapping, detailed comments and 3 automated tests. Premium also saves the result to one existing PostgreSQL or MySQL table and includes a persistence test.
Can you integrate any API or authentication method?
These packages cover documented REST APIs using an API key or an existing valid token. New OAuth flows, payments, webhooks and two-way synchronization require a separate assessment and quote. Compatibility is confirmed before ordering. Third-party API subscriptions and usage fees are not included.
What does the revision include, and do you provide ongoing support?
One revision covers adjustments within the agreed endpoint, fields and behavior. Errors in my delivered code against the agreed requirements will be corrected without an extra charge. New features, existing app bugs, deployment, provider API changes and ongoing maintenance are outside the package.
