I will integrate your apis and automate your business workflows
Yehor I
About this gig
Need your systems to exchange data without repetitive copy-paste or fragile manual steps?
I build focused REST API integrations, webhooks and business workflow automation using Node.js and TypeScript.
I can help you:
- Connect two business systems
- Synchronize selected data
- Set up and process webhooks
- Automate CRM, payment or notification workflows
- Troubleshoot an existing integration
- Add validation, error handling and logging
- Create a small internal integration service
Each package limits the number of systems and API endpoints. One endpoint means one defined API operation or webhook event in the agreed workflow.
Third-party subscriptions, usage fees, undocumented private APIs, large data migrations and complete custom applications are not included.
The final price depends on the number of systems, endpoints, authentication methods and workflow branches. Please message me before ordering if the documentation is incomplete, the API is private or your scope does not match a package.

FAQ
Should I contact you before ordering?
Yes. Please contact me first if the API is private, documentation is incomplete, or the number of systems, endpoints and workflow branches is unclear.
What do you need to estimate the integration?
Please share the systems involved, API documentation, required data flow, endpoints, authentication method, expected error handling and target environment.
How do you determine integration complexity?
Complexity depends on the systems, endpoints, authentication methods, data transformations, workflow branches, rate limits, testing needs and deployment environment.
What counts as one API endpoint?
One endpoint is one defined API operation, such as retrieving a record, creating an item or processing one webhook event in the agreed workflow.
Which authentication methods can you work with?
I can work with documented API keys, bearer tokens, OAuth flows and other standard methods. Scope depends on provider requirements and available test access.
Is deployment included?
Deployment is included only when stated in the package or selected as an extra. Hosting accounts, subscriptions, infrastructure fees and production approvals are not included.
Can you work with an existing integration?
Yes. I can troubleshoot or extend existing Node.js and TypeScript integration code after reviewing the repository, logs and current API behavior.
What counts as a revision?
A revision is an adjustment to the agreed integration behavior. A new system, endpoint, authentication flow or workflow branch is additional scope.
How do you handle access and confidential information?
I request minimum permissions and keep communication on Fiverr. Do not paste passwords, tokens, secret keys or personal data into an open requirement field.
What if my workflow does not fit a package?
Send a concise workflow description with systems, endpoints and constraints. I can define a bounded scope and prepare a custom offer after review.
