We are looking for: Backend Developer — Zoho Books Integration via API (Freelancer)
Remote | Integration project with defined scope
Who are we?
redBLak is a digital telecommunications startup. There is no bureaucracy here — there are quick decisions and concrete projects.
We need to integrate Zoho Books with our internal systems via API. We are looking for someone who has already done this before — we do not want someone who learns on our project.
What you will do:
- Design and implement the integration between Zoho Books and our systems via REST API
- Handle OAuth authentication, webhooks, and data synchronization
- Document the integration flow clearly
- Identify and resolve errors in the data connection (invoices, payments, catalogs)
Profile we are looking for:
- Proven experience integrating Zoho Books (or Zoho in general) via API — tell us which project you did it in
- Mastery of at least one backend language (Python, Node.js, PHP, or similar)
- Knowledge of OAuth 2.0 authentication and REST API management
- Delivery of documentation as part of the work, not as an extra
Job Type: Temporary, Contract
Work Location: Remote job
