Zoho CRM / Deluge Expert Needed for API Integration

We need an experienced Zoho developer to build a REST API integration between Zoho and ZimpleMoney, a third-party payment platform. This includes taking over our existing Deluge setup, building custom invokeurl functions, mapping JSON payloads, and running a historical data import. ⚠️ Screening question (read first): What is the exact Deluge task/function used to execute an HTTP/REST API request? Your proposal must answer this in the first line, or it will be archived unread. Scope of work Connect Zoho to ZimpleMoney via REST API (OAuth 2.0 / API keys), with secure header and auth handling. Import historical contracts, ledger entries, and transaction records into Zoho custom modules/CRM fields via Deluge. Set up ongoing sync — scheduled Deluge functions or incoming webhooks — to pull real-time contract and payment updates. Handle JSON field mapping, API pagination, rate limits, and error logging (200 vs. 400/500). Build and test everything in Zoho Sandbox against ZimpleMoney's sandbox before deploying to production. Requirements -Strong Deluge experience in Zoho -CRM/Creator/Books. -Proven work with REST APIs, invokeurl, JSON parsing, and webhooks. -Experience with data migrations and API rate-limit handling. -Comfortable working independently through a sandbox-to-production workflow. To apply, include: 1) Your answer to the screening question (line 1). 2) Examples of Zoho-to-payment/financial-platform or similar integrations you've built. 3) Estimated turnaround for testing and deployment once sandbox credentials are provided.
