I will develop a go backend API and integrations


About this gig
We develop production-grade Go backends, REST APIs, webhooks and business integrations for SaaS products and internal systems.
This Gig is for teams that need more than an endpoint that only works in a happy-path demo. We design for validation, permissions, retries, idempotency, observability and maintainable handover.
Depending on the package, we can deliver:
- Go REST API or backend service
- PostgreSQL data model and migrations
- authentication and role-based access
- payment, CRM, messaging or data-provider integrations
- webhooks, queues and background jobs
- OpenAPI/Swagger documentation
- unit and integration tests
- Docker, CI and deployment guidance
Our team uses Go in real subscription and AI products, including SoykaVPM and YouConnect.
Please message us before ordering with the API documentation, required data flow and current stack. We will confirm the boundaries and recommend the correct package.

FAQ
Can you integrate an API that has poor documentation?
Usually yes, after a short investigation. If discovery is significant, we will quote it separately before development.
Will you provide Swagger or OpenAPI documentation?
Yes. Standard and Premium packages include API documentation for the delivered endpoints.
Can you add endpoints to an existing Go service?
Yes, after reviewing the repository structure, conventions, tests and deployment environment.
Do you handle payment webhooks safely?
Yes. We implement signature validation, idempotency, retries and clear status transitions when supported by the provider.
Are deployment and Docker included?
Docker is included in Standard and Premium. Production infrastructure changes are confirmed separately based on your environment.
Which access should I provide?
Only the minimum required access, shared through the Fiverr order workspace. Use test credentials whenever possible and rotate production secrets after handover.
