REST API Integration Specialist

@AwaisChaudhry

Hi there, I’ll plug your existing service flow into the external CRM via its REST API with clean, production-ready requests, handle authentication, and return the sales data you specify in exact JSON to your webhook. I’ll build a small, readable integration layer that respects your endpoint docs and tokens, preserves field names, types, and nesting, and includes concise inline comments plus a short handover note for your team. The work will cover sandbox and live environments, thorough error handling, and reproducible setup steps so a fresh environment can be set up quickly. If you’ve shipped similar CRM integrations, I can share quick references and timelines on request. 1) Confirm the exact auth method (API key vs OAuth 2.0) and how tokens are rotated; what are the sandbox and production credentials and scopes? 2) Can you share sample sales data payload structure and required field mappings to preserve nesting and types exactly as documented? 3) What is the webhook endpoint format, expected HTTP method, headers, and retry policy? Any special headers for retries? 4) What testing strategy do you prefer (unit/integration) and can you provide a sandbox test plan, along with any CI requirements? 5) Do you have a preferred naming convention, error handling standards, and logging requirements for audit trails? Best regards,

Hello, I will integrate your existing service flow with the external CRM using its REST API by building clean, reliable and fully authenticated requests. I will handle authentication, structure the API calls correctly, retrieve the exact sales data you specify, return it in perfectly formatted JSON, preserving all field names, types, nesting as documented. I will ensure the responses are delivered into your existing automation flow through your provided webhook, add clear inline comments for maintainability, and provide a short hand-over note so your team can easily reproduce and manage the setup in any environment. Looking forward to discussing further. Best regards, Kamran

Hi, I have solid experience integrating CRMs via REST APIs and building reliable automation flows with clean JSON handling and authentication logic. I can connect your service flow to the CRM, return the exact sales data structure you need, and provide clear documentation for your team to maintain it. I can start quickly and ensure everything works in sandbox and production. Can you tell me which CRM it is (for example HubSpot, Salesforce, Zoho, GoHighLevel, or a custom CRM)? That will help me tailor the integration approach and authentication method correctly.

@mughiraaa

Hello, I have reviewed the details of your project. i will review the crm api docs and mapping the exact sales fields you need into a clear json structure. the integration will be written in node js using fetch for rest calls so requests stay simple and readable. authentication will use the crm token flow with headers stored in environment variables to keep things safe. each call will validate status codes parse responses and return clean json into your existing webhook flow with no data loss. i will test against sandbox then live to confirm matching output. the final delivery will include clear inline comments and a short setup note so your team can run this in a fresh environment with confidence. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you.

Hello, I hope you are doing well. I’m a backend engineer specializing in robust REST API integrations. I translate business flows into clean, production-grade calls with solid authentication, clear error handling, and dependable JSON responses so the automation sequence stays predictable. I’ve previously stitched CRM REST APIs using OAuth2 or API keys, built data-mapping layers to preserve exact field names and nesting, and delivered precise JSON payloads to webhooks—no flaky mappings or missing fields. I’ve used Postman for testing, Python or Node to implement the connectors, and provided thorough inline comments plus a hand-over note for your team. I can handle this end-to-end, delivering a production-ready integration that respects field names, types, and nesting, with clear code and a reproducible setup. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan
