.NET Email Approval API

@ambar

Most of this API is straightforward. The part worth getting right is correlation. When somebody clicks Approve or Deny from an email hours or days later, the system must know exactly which request they are responding to and preserve all custom fields that came in with the original payload. While reviewing your requirements, I found several ASP.NET approval workflow implementations that already solve tokenized response tracking. Rather than inventing that mechanism from scratch, I'd use the same proven pattern and adapt it to your workflow. That removes a lot of risk from the only part of the project that tends to cause trouble. ✔ Flexible JSON payloads without fixed models ✔ SMTP email delivery ✔ Approve / Deny + comments ✔ Decision returned as clean JSON ✔ Full audit trail of every action ✔ Swagger, Postman and Docker Question: should the approval result be pushed immediately to your system via webhook, or should your application retrieve it when needed?

This looks like a great fit, I will build the .NET Web API — flexible JSON intake endpoint, SMTP email dispatch with Approve/Deny actions and comment capture, and a callback endpoint returning the decision as clean JSON. I will use a dictionary-based payload model so custom fields pass through without code changes. For the email response capture, I will generate a unique token per request to prevent replay or tampering when users click Approve/Deny. Questions: 1) Should the decision landing page be a minimal embedded HTML form or a separate hosted page? 2) Do you need response expiration — e.g., auto-deny after 48 hours? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Send me a message and we can go over the details. Best regards, Kamran

@AqdasIftekhar

Hi, I can build this in .NET 8 (LTS) with a clean, layered architecture and Docker support. The API will accept flexible JSON payloads, send approval emails through standard SMTP authentication, capture Approve/Deny + comments, and expose the final decision via a JSON endpoint (or webhook push if preferred). The solution will include: 1. Clean separation of concerns (Controllers, Services, Repositories, SMTP helper) 2. Structured logging, validation, and graceful error handling 3. Swagger/OpenAPI and Postman collection 4. Sample request/response payloads supporting arbitrary custom fields 5. Dockerfile and README with environment variables for SMTP configuration 6. Well-documented Visual Studio solution with maintainable C# code I have extensive experience with .NET and API development and can deliver a lightweight, production-ready solution. Best regards, Aqdas Iftekhar

@mohjib092

Hi there, I can quickly build this clean .NET C# Web API with flexible JSON intake, SMTP approval emails, approve/deny response capture, logging, validation, Swagger/Postman testing, Docker setup, and clear README so you can test the full flow immediately. I’ll build it as a clean .NET 8 Web API with one POST endpoint for flexible JSON intake, an SMTP service to send approval emails, a secure approve/deny response page with comments, a result endpoint returning JSON, full logging/error handling, Swagger/Postman tests, Docker support, and a short README for setup. Best regards, Muhammad Jibran Ahmed

@talkwaqar

Two details stood out: the flexible JSON schema so you can pass custom fields without code changes, and the approve/deny email with a free-text comment that pushes the decision back as clean JSON. The tricky part isn't the SMTP send, it's making the email action links durable and tying the click back to the original request safely. Week one I'd ship the POST-in to email-out path so you can see a real approval email land. Here's the build: 1. POST endpoint accepts arbitrary JSON (stored as a flexible document), validated for the recipient and a request ID only. 2. SMTP helper service (plain username/password auth, host/port/creds via environment variables) sends the email with signed Approve and Deny links plus a comment field. 3. Decision endpoint captures the click and comment, logs every step, and exposes the result as clean JSON for your system to pull. I build webhook-confirmed flows like this regularly, including idempotent state flips where a click must map back to exactly one request without double-processing. The solution ships as a Visual Studio solution on the latest LTS .NET, with separated controllers/services/SMTP helper, sample request/response JSON, a Docker README, and a Swagger collection so you can test immediately. Timeline: 7 days at $162. Done = you post a JSON file, watch the email go out, click a response, and receive the decision back through the API. Do you want the approval links to be single-use and time-limited (expire after, say, 72 hours), or stay valid until a decision is made? P.S. I'd sign the action links with an HMAC token rather than a raw request ID in the URL, so a guessed or forwarded link can't approve someone else's request. Waqar

@osamak74

I can build this as a clean .NET Core Web API with flexible JSON input, SMTP-based approval emails, and a clear decision callback flow. The focus will be separation of concerns, solid validation, and traceable logs so your process is easy to maintain and extend without code changes. I’d structure the solution with controllers, services, and an SMTP helper, then expose endpoints for submission and decision capture, plus sample JSON, Swagger/Postman, and a brief README for local or Docker setup. I can start immediately. Do you want the approval/deny link to update your system by callback URL or by polling a status endpoint? Should the free-text comment be required for both Approve and Deny, or only on Deny? Happy to discuss the implementation details and get this moving. Osama
